So the equation for Over is: - * - * dst.A = src.A * mask.A + (1 - (src.A * mask.A)) * dst.A - * dst.R = src.R * mask.R + (1 - (src.A * mask.R)) * dst.R - * dst.G = src.G * mask.G + (1 - (src.A * mask.G)) * dst.G - * dst.B = src.B * mask.B + (1 - (src.A * mask.B)) * dst.B - * - * But we can do some simpler operations, right? How about PictOpOutReverse, - * which has a source factor of 0 and dest factor of (1 - source alpha). We - * can get the source alpha value (srca.X = src.A * mask.X) out of the texture - * blenders pretty easily. So we can do a component-alpha OutReverse, which - * gets us: - * - * dst.A = 0 + (1 - (src.A * mask.A)) * dst.A - * dst.R = 0 + (1 - (src.A * mask.R)) * dst.R - * dst.G = 0 + (1 - (src.A * mask.G)) * dst.G - * dst.B = 0 + (1 - (src.A * mask.B)) * dst.B - * - * OK. And if an op doesn't use the source alpha value for the destination - * factor, then we can do the channel multiplication in the texture blenders - * to get the source value, and ignore the source alpha that we wouldn't use. - * We've supported this in the Radeon driver for a long time. An example would - * be PictOpAdd, which does: - * - * dst.A = src.A * mask.A + dst.A - * dst.R = src.R * mask.R + dst.R - * dst.G = src.G * mask.G + dst.G - * dst.B = src.B * mask.B + dst.B - * - * Hey, this looks good! If we do a PictOpOutReverse and then a PictOpAdd right - * after it, we get: - * - * dst.A = src.A * mask.A + ((1 - (src.A * mask.A)) * dst.A) - * dst.R = src.R * mask.R + ((1 - (src.A * mask.R)) * dst.R) - * dst.G = src.G * mask.G + ((1 - (src.A * mask.G)) * dst.G) - * dst.B = src.B * mask.B + ((1 - (src.A * mask.B)) * dst.B) - */ - -static int -exaTryMagicTwoPassCompositeHelper(CARD8 op, - PicturePtr pSrc, - PicturePtr pMask, - PicturePtr pDst, - INT16 xSrc, - INT16 ySrc, - INT16 xMask, - INT16 yMask, - INT16 xDst, - INT16 yDst, - CARD16 width, - CARD16 height) -{ - ExaScreenPriv (pDst->pDrawable->pScreen); - - assert(op == PictOpOver); - - if (pExaScr->info->CheckComposite && - (!(*pExaScr->info->CheckComposite)(PictOpOutReverse, pSrc, pMask, - pDst) || - !(*pExaScr->info->CheckComposite)(PictOpAdd, pSrc, pMask, pDst))) - { - return -1; - } - - /* Now, we think we should be able to accelerate this operation.

Mainly used for component + * alpha and limited 1-tmu cards. + * + * From http://anholt.livejournal.com/32058.html: + * + * The trouble is that component-alpha rendering requires two different sources + * for blending: one for the source value to the blender, which is the + * per-channel multiplication of source and mask, and one for the source alpha + * for multiplying with the destination channels, which is the multiplication + * of the source channels by the mask alpha. So the equation for Over is: + * + * dst.A = src.A * mask.A + (1 - (src.A * mask.A)) * dst.A + * dst.R = src.R * mask.R + (1 - (src.A * mask.R)) * dst.R + * dst.G = src.G * mask.G + (1 - (src.A * mask.G)) * dst.G + * dst.B = src.B * mask.B + (1 - (src.A * mask.B)) * dst.B + * + * But we can do some simpler operations, right? How about PictOpOutReverse, + * which has a source factor of 0 and dest factor of (1 - source alpha). We + * can get the source alpha value (srca.X = src.A * mask.X) out of the texture + * blenders pretty easily. So we can do a component-alpha OutReverse, which + * gets us: + * + * dst.A = 0 + (1 - (src.A * mask.A)) * dst.A + * dst.R = 0 + (1 - (src.A * mask.R)) * dst.R + * dst.G = 0 + (1 - (src.A * mask.G)) * dst.G + * dst.B = 0 + (1 - (src.A * mask.B)) * dst.B + * + * OK.

- - - - Scaled Window Support in DMX - - Kevin E.Martin - Rickard E.Faith - - 15 October 2003 (created 19 September 2003) - - - This document investigates the possibility of adding scaled window - support to the DMX X server, thereby allowing a window or some - selected part of the logical DMX area to be displayed using a - scaling factor. For example, this might allow the contents of a - window to be magnified for easier viewing. In particular, scaling - for the VNC client is explored. Copyright 2003 - by Red Hat, Inc., Raleigh, North Carolina - - - - - - Introduction - DMX - - The DMX X server (Xdmx) is a proxy server that is designed - to allow X servers on multiple machines to be combined into - a single multi-headed X server. Combined with Xinerama, - these heads can appear as a single very high-resolution - screen. Typical applications include the creation of a - video wall with 16 1280x1024 displays arranged in a - rectangle, for a total resolution of of 5120x4096. - - - Problem Statement - - Applications displayed on a physically large video wall that - provides high pixel-resolution may be difficult to see, - especially if the application is designed for use on a - typical desktop computer with a relatively small display - located close to the human operator. The goal of this paper - is to describe and discuss solutions to this problem. - - - The original driving problem for this work is to provide - scaling for the vncviewer application when - displayed using DMX (VNC scaling is currently available only - with the Windows client, and there is no plan to extend that - capability to other clients). While this specific problem - will be addressed in this paper, the general solution space - will also be explored, since this may lead to a good - solution not only for vncviewer but also for - other applications. - - - Task - - For reference, here is the original description of the task - this paper addresses: - - Scaled window support (for VNC) - - - Investigate possibility of implementing a "scaled - window" extension: - - - Add XCreateScaledWindow call that could be used - in place of XCreateWindow - - - All primitives drawn to scaled window would be - scaled by appropriate (integral?) scaling factor - - - - - Alternate approach: special case VNC support - - - - - - - - - Previous Work - - This section reviews relevant previous work. - - VNC - Scaling under VNC - - When using the vncviewer program for Windows, it - is possible to specify a scaling factor (as numerator and - denominator). When scaling is in effect, the viewer - software uses StretchBlt (instead of BitBlt) to display - the pixels for the user. When this call is made, the - viewer already has received all of the pixel information - (at full unscaled resolution). - - - The scaling in VNC is primitive. It does not conserve - bandwidth, it does not treat textual information - differently (i.e., by using a suitably scaled font), and - it does not provide any anti-aliasing other than that - provided by the underlying (Windows-only) system library. - - - - The X Video Extension - - The X Video Extension is a widely-available extension to the - X11 protocol that provides support for streaming video. - Integral to this support is the ability to arbitrarily scale - the output. In version 2.2 of the X Video specification, - support for scaled still images was provided, using both - shared memory and traditional transport. The API for this - support uses calls that are quite similar to XCreateWindow, - XPutImage, and XShmPutImage. Currently, most of the drivers - implemented in XFree86 only support data in various YUV - formats. However, several modern video adaptors support RGB - as well. - - - Note, though, that the target output for this scaling is an - overlay plane -- so X Video provides functionality that is - fundamentally different from that provided by the Windows - StrechBlt call. - - - - - Possible Solutions - - This section briefly discusses possible solutions, including - major advantages and disadvantages from both the - implementation and the end-user programmer standpoint. - - VNC-like Scaling - Software Scaling - - The vncviewer application could be modified to - provide software scaling. This is not a general solution, - but it does solve one of the goals of this work. - - - A prototype of this solution was implemented and a patch - against vnc-3.3.7-unixsrc is available in the - dmx/external directory. Because of limited time - available for this work, all of the edge cases were not - considered and the solution works well mainly for integer - scaling. - - - Currently, vncviewer writes to the X display - with XPutImage, XCopyArea, and XFillRectangle. All - instances of these calls have to be aware of scaling - and must round correctly. In the prototype solution, - rounding is incorrect and can cause artifacts. - - - A better solution would be to cache all updates to the - desktop image in vncviewer and only send the - damaged area to the X display with XPutImage. This would - allow the damaged area to be computed so that rounding - errors do not create artifacts. This method is probably - similar to what is used in the Window client. (The whole - VNC suite is being re-written in C++ and the forthcoming - version 4 has not been evaluated.) - - - Scaling with the X Video Extension - - The scaling in the Windows vncviewer application - makes use of a scaled blit that is supplied by the - underlying system library. Several video cards currently - provide support for a scaled blit, and some X servers - (including XFree86) expose this capability to applications - via the XvPutImage interface of the X Video Extension. - The capability exposed by XvPutImage results in the scaled - image being drawn to an overlay plane. Most video cards - also provide support for a scaled blit into the normal - output planes, but this is not exposed via XvPutImage. - - - The vncviewer program could be modified to use - the X Video Extension to provide scaling under X11 that is - similar to the scaling currently provided under Windows. - Unfortunately, Xdmx does not currently export the X Video - Extension, so this would not provide an immediate solution - usable with DMX. - - - A very early-stage proof-of-concept prototype was - implemented and a preliminary patch against - vnc-3.3.7-unixsrc is available in the - dmx/external directory.

Unlike the X Video - Extension, which writes into an overlay plane, - XCopyAreaScaled would write into the non-overlay areas of - the screen. Key points to consider are as follows: - - - Because different planes are involved, the two scaling - operations are usually implemented in hardware - differently, so an XCopyAreaScaled extension could be - added in a manner that would neither conflict with nor - interact with the X Video extension in any way. - - - The XCopyAreaScaled extension provides new - functionality that the X Video Extension does not - provide. Based on anecdotal feedback, we believe that - many people outside the DMX and VNC communities would - be excited about this extension. - - - The main drawback to this extension is that it is new - and needs to be implemented at the driver level in - XFree86 for each video card to be supported. At the - present time, it is more likely that the X Video - Extension will be implemented for a particular piece - hardware because the X Video extension has multimedia - uses. However, over time, we would expect the - XCopyAreaScaled extension to be implemented along with - the X Video extension, especially if it becomes - popular. - - - Another drawback is that not all modern cards provide - support for a simple scaled blit operation. However, - these cards usually do provide a 3D pipeline which - could be used to provide this functionality in a - manner that is transparent to the client application - that is using the XCopyAreaScaled extension. However, - this implementation pathway would make this extension - somewhat more difficult to implement on certain cards. - - - - - Scaling with OpenGL - - Another general solution to the scaling problem is to use - the texture scaling found in all 3D hardware. This - ability is already exposed through OpenGL and can be - exploited by clients without X server modification (i.e., - other than the ability to support OpenGL). An application - using OpenGL would transmit the non-scaled image to the X - server as a texture, and would then display a single - non-transformed rect using that texture. This also works - around the single overlay problem with the X Video - Extension as well as the need to implement additional - scaled primitive extensions. - - - The downside is that most OpenGL implementations require - power of 2 texture sizes and this can be very wasteful of - memory if, for example, the application needs to scale a - 1025x1025 image, which would require a 2048x2048 texture - area (even a 640x480 image would require a 1024x512 - texture). Another downside is that some OpenGL - implementations have a limited about of texture memory and - cannot handle textures that are very large. For example, - they might limit the texture size to 1024x1024. - - - - Application-transparent Scaling for DMX - Back-end Scaling Without Disconnect/Reconnect - - VNC does scaling on the client side (in the - vncviewer application). Implementing a similar - solution for DMX would require support in the back-end X - servers and, therefore, is not a general solution. - - - XFree86 already implements some support for "scaling" that - could be used with DMX: if, in the XF86Config file, - multiple Modes are listed in the Display Subsection of the - Screen Section, then pressing Ctrl-Alt-Plus and - Ctrl-Alt-Minus can be used to iterate through the listed - modes. The display dimensions will change to the - dimensions in the Modes line, but the logical dimensions - of the X server (i.e., the dimensions that Xdmx knows - about) will not change. - - - Further, the dimensions of the XFree86 display are under - software control (via the XFree86-VidModeExtension), so - the Xdmx server could change the screen dimensions on a - per-display basis, thereby scaling the information on part - of that display. - - - However, this scaling appears to have limited use. For - example, assume a 4 by 4 display wall consisting of 16 - 1280x1024 displays. If all of the back-end servers were - simultaneously configured to display 640x480, the left - hand corner of each display would be magnified, but the - composite result would be unreadable. Magnifying one - display at a time could be usable, but could have limited - utility, since the result would still be no larger than a - single display. - - - Back-end Scaling With Disconnect/Reconnect - - Disconnect and reconnect features are not currently - supported in DMX, but are scheduled to be implemented in - the future. These features, combined with the - XFree86-VidModeExtension Extension, would allow an - application to do the following: - - - Disconnect a specific back-end server (via the DMX - Extension), - - - reconfigure the XFree86 back-end server resolution, - and - - - reconnect the back-end server to DMX -- at a new - origin with the new screen resolution. - - - - - For example, consider a display wall consisting of 16 - 1280x1024 displays with a total resolution of 5120x4096. - All of the screens could be disconnected, repositioned, - and reconnected each at a resolution of 640x480. The - total resolution of the display wall would be 2560x1920, - allowing a view of a selected area approximately - one-fourth of the size of the DMX display. This change - would be completely application independent (except, - perhaps, for a DMX-aware window manager). When work at - the increased resolution was completed, the back-end - servers could be disconnected, reconfigured, and - reconnected for the original 5120x4096 view. - - - Support for this type of scaling can be implemented in a - DMX-aware X11 client assuming the DMX server support - arbitrary disconnect and reconnect semantics. Because - this application cannot be written before - disconnect/reconnect is implemented, this solution will - not be discussed further in this paper. - - - Server-side Scaling - - In earlier versions of DMX, a frame buffer was maintained - on the server side, and XPutImage was used to move the - information from the server to the client (similar to some - early VNC implementations). The use of a server-side - frame buffer would allow the server to do scaling, but is - not a recommended solution because of overall performance - issues and server-side memory issues (i.e., the frame - buffer would be very large for large display walls). - - - Exploration of this path is not recommended. - - - - XCreateScaledWindow API - - The implementation of X Video Extension in DMX, and the use - of XvPutImage by applications requiring scaling requires - significant changes in DMX Further, XvPutImage is, - essentially a scaled blit, and it is only useful for - applications which are already using (or can be modified to - use) XPutImage. Therefore, a more general API will be - discussed as another possibility. - - - X applications typically create windows with the - XCreateWindow call. A new extension could provide an - XCreateScaledWindow call that could be used in place of the - XCreateWindow call and be otherwise transparent to the - application. This would allow applications, even those that - do not depend on XPutImage, to take advantage of window - scaling. In this section we describe how the call would - work, what transparency it provides, and how to solve the - potential problems that transparency creates. - - XCreateWindow - - The XCreateWindow call takes width and height as - parameters. An XCreateScaledWindow call could take all - the same parameters, with the addition of a scaling factor. - - - XSetWindowAttributes - - An X11 window has several attributes that would have to be - scaled: - - Background and border pixmaps - Border width - Cursor - - - - XGetWindowAttributes, XGetGeometry - - For transparency, calls that query the window attributes - should return unscaled information. This suggests that - all unscaled pixmaps and window attributes should be - cached. - - - Unfortunately, a window manager requires the scaled - geometry to properly decorate the window. The X server - can probably determine which client is acting as the - window manager (e.g., because that client will select - events that are used exclusively by the window manager). - However, other Scaled Window Extension aware clients may - also need to determine the scaled geometry. Therefore, at - least two additional extension calls should be - implemented: XGetScaledWindowAttributes and - XGetScaledGeometry. - - - Popup and Child window positions - - Some applications may position popup and child windows - based on an unscaled notion of the main window geometry. - In this case, additional modifications to the client would - be required. - - - Events - - Most events (e.g., for mouse motion) return information - about the coordinates at which the even occurred. These - coordinates would have to be modified so that unscaled - values were presented to the client. - - - Implementation - - There are many implementation issues, some of which are - similar to the issues involved in implementing the X Video - Extension for DMX. The window contents must be scaled, - either by performing all operations to a frame buffer and - then writing the image to the display (perhaps using - hardware scaling support), or by modifying all of the - various drawing operations to perform scaling. Because of - the complexity involved, the frame buffer option is - recommended. - - - - - - Conclusion and Recommendations - - We recommend a three phase implementation strategy, based on - how an application could be written to take advantage of - scaling: - - - - The XCopyAreaScaled extension should be implemented, since - this is the ideal solution for applications like VNC, and - since making use of this extension will require minimal - changes to applications that already use XPutImage or - XCopyArea. - - - The initial implementation work would include the design - of the X protocol extension, writing this up in the - usual format for extension documentation, implementation - of the protocol transport pieces in XFree86, - implementation of a software fall-back in XFree86 and - DMX, one example hardware implementation for XFree86, - and implementation of support for this extension in DMX. - - - We suggest implementing the extension first on the ATI - Radeon cards. However, since these cards do not provide - a 2D scaled blit primitive, the implementation would - have to make use of the 3D texture engine to emulate a - scaled blit. This is recommended, since other modern - graphics cards also do not provide a simple 2D scaled - blit operation and an example of the more difficult - implementation pathway would be helpful to others. - - - - - Until XCopyAreaScaled is widely supported, applications - that require scaling will have to fall back to another - scaling method. We suggest OpenGL as the first fall-back - method because it is widely available and supported by - DMX. - - - A project centered around OpenGL-based scaling would - implement this scaling in VNC as an example. This work - would include re-writing the vncviewer - rendering engine to cache a master copy of the desktop - image for all operations. - - - - - Since OpenGL is not implemented everywhere, and may not - provide hardware-assisted performance in every - implementation, an application that requires scaling - should also fall back to using the X Video Extension. - - - This project would add support for the X Video Extension - to DMX and would add support to VNC to take advantage of - this extension without introducing artifacts. This - would require modifying the vncviewer rendering - engine to cache a master copy of the desktop image for - all operations. This project should also add support - for the RGB format to at least one XFree86 driver (e.g., - ATI Radeon). - - - The X Video Extension is one of the few popular - extensions that DMX does not support. We recommend - implementing the X Video Extension even if scaling is - the specific goal of that work. - - - - - - We do not recommend implementation of the - XCreateScaledWindow extension because of the complexity - involved. We do not recommend implementation of the - XPutImageScaled extension because it requires the same amount - of work as the XCopyAreaScaled extension, but provides less - functionality. Further, server-side scaling with a large - frame buffer is not recommended because of the - performance implications. - - - The back-end scaling, especially with disconnect/reconnect - support should be explored in the future after - disconnect/reconnect is implemented, but not at the present - time. - - - -

+ + + + Scaled Window Support in DMX + + Kevin E.Martin + Rickard E.Faith + + 15 October 2003 (created 19 September 2003) + X Server Version &xserver.version; + + + This document investigates the possibility of adding scaled window + support to the DMX X server, thereby allowing a window or some + selected part of the logical DMX area to be displayed using a + scaling factor. For example, this might allow the contents of a + window to be magnified for easier viewing. In particular, scaling + for the VNC client is explored. Copyright 2003 + by Red Hat, Inc., Raleigh, North Carolina + + + + + + Introduction + DMX + + The DMX X server (Xdmx) is a proxy server that is designed + to allow X servers on multiple machines to be combined into + a single multi-headed X server. Combined with Xinerama, + these heads can appear as a single very high-resolution + screen. Typical applications include the creation of a + video wall with 16 1280x1024 displays arranged in a + rectangle, for a total resolution of of 5120x4096. + + + Problem Statement + + Applications displayed on a physically large video wall that + provides high pixel-resolution may be difficult to see, + especially if the application is designed for use on a + typical desktop computer with a relatively small display + located close to the human operator. The goal of this paper + is to describe and discuss solutions to this problem. + + + The original driving problem for this work is to provide + scaling for the vncviewer application when + displayed using DMX (VNC scaling is currently available only + with the Windows client, and there is no plan to extend that + capability to other clients). While this specific problem + will be addressed in this paper, the general solution space + will also be explored, since this may lead to a good + solution not only for vncviewer but also for + other applications. + + + Task + + For reference, here is the original description of the task + this paper addresses: + + Scaled window support (for VNC) + + + Investigate possibility of implementing a "scaled + window" extension: + + + Add XCreateScaledWindow call that could be used + in place of XCreateWindow + + + All primitives drawn to scaled window would be + scaled by appropriate (integral?) scaling factor + + + + + Alternate approach: special case VNC support + + + + + + + + + Previous Work + + This section reviews relevant previous work. + + VNC + Scaling under VNC + + When using the vncviewer program for Windows, it + is possible to specify a scaling factor (as numerator and + denominator). When scaling is in effect, the viewer + software uses StretchBlt (instead of BitBlt) to display + the pixels for the user. When this call is made, the + viewer already has received all of the pixel information + (at full unscaled resolution). + + + The scaling in VNC is primitive. It does not conserve + bandwidth, it does not treat textual information + differently (i.e., by using a suitably scaled font), and + it does not provide any anti-aliasing other than that + provided by the underlying (Windows-only) system library. + + + + The X Video Extension + + The X Video Extension is a widely-available extension to the + X11 protocol that provides support for streaming video. + Integral to this support is the ability to arbitrarily scale + the output. In version 2.2 of the X Video specification, + support for scaled still images was provided, using both + shared memory and traditional transport. The API for this + support uses calls that are quite similar to XCreateWindow, + XPutImage, and XShmPutImage. Currently, most of the drivers + implemented in XFree86 only support data in various YUV + formats. However, several modern video adaptors support RGB + as well. + + + Note, though, that the target output for this scaling is an + overlay plane -- so X Video provides functionality that is + fundamentally different from that provided by the Windows + StrechBlt call. + + + + + Possible Solutions + + This section briefly discusses possible solutions, including + major advantages and disadvantages from both the + implementation and the end-user programmer standpoint. + + VNC-like Scaling + Software Scaling + + The vncviewer application could be modified to + provide software scaling. This is not a general solution, + but it does solve one of the goals of this work. + + + A prototype of this solution was implemented and a patch + against vnc-3.3.7-unixsrc is available in the + dmx/external directory. Because of limited time + available for this work, all of the edge cases were not + considered and the solution works well mainly for integer + scaling. + + + Currently, vncviewer writes to the X display + with XPutImage, XCopyArea, and XFillRectangle. All + instances of these calls have to be aware of scaling + and must round correctly. In the prototype solution, + rounding is incorrect and can cause artifacts. + + + A better solution would be to cache all updates to the + desktop image in vncviewer and only send the + damaged area to the X display with XPutImage. This would + allow the damaged area to be computed so that rounding + errors do not create artifacts. This method is probably + similar to what is used in the Window client. (The whole + VNC suite is being re-written in C++ and the forthcoming + version 4 has not been evaluated.) + + + Scaling with the X Video Extension + + The scaling in the Windows vncviewer application + makes use of a scaled blit that is supplied by the + underlying system library. Several video cards currently + provide support for a scaled blit, and some X servers + (including XFree86) expose this capability to applications + via the XvPutImage interface of the X Video Extension. + The capability exposed by XvPutImage results in the scaled + image being drawn to an overlay plane.

Because + this application cannot be written before + disconnect/reconnect is implemented, this solution will + not be discussed further in this paper. + + + Server-side Scaling + + In earlier versions of DMX, a frame buffer was maintained + on the server side, and XPutImage was used to move the + information from the server to the client (similar to some + early VNC implementations). The use of a server-side + frame buffer would allow the server to do scaling, but is + not a recommended solution because of overall performance + issues and server-side memory issues (i.e., the frame + buffer would be very large for large display walls). + + + Exploration of this path is not recommended. + + + + XCreateScaledWindow API + + The implementation of X Video Extension in DMX, and the use + of XvPutImage by applications requiring scaling requires + significant changes in DMX Further, XvPutImage is, + essentially a scaled blit, and it is only useful for + applications which are already using (or can be modified to + use) XPutImage. Therefore, a more general API will be + discussed as another possibility. + + + X applications typically create windows with the + XCreateWindow call. A new extension could provide an + XCreateScaledWindow call that could be used in place of the + XCreateWindow call and be otherwise transparent to the + application. This would allow applications, even those that + do not depend on XPutImage, to take advantage of window + scaling. In this section we describe how the call would + work, what transparency it provides, and how to solve the + potential problems that transparency creates. + + XCreateWindow + + The XCreateWindow call takes width and height as + parameters. An XCreateScaledWindow call could take all + the same parameters, with the addition of a scaling factor. + + + XSetWindowAttributes + + An X11 window has several attributes that would have to be + scaled: + + Background and border pixmaps + Border width + Cursor + + + + XGetWindowAttributes, XGetGeometry + + For transparency, calls that query the window attributes + should return unscaled information. This suggests that + all unscaled pixmaps and window attributes should be + cached. + + + Unfortunately, a window manager requires the scaled + geometry to properly decorate the window. The X server + can probably determine which client is acting as the + window manager (e.g., because that client will select + events that are used exclusively by the window manager). + However, other Scaled Window Extension aware clients may + also need to determine the scaled geometry. Therefore, at + least two additional extension calls should be + implemented: XGetScaledWindowAttributes and + XGetScaledGeometry. + + + Popup and Child window positions + + Some applications may position popup and child windows + based on an unscaled notion of the main window geometry. + In this case, additional modifications to the client would + be required. + + + Events + + Most events (e.g., for mouse motion) return information + about the coordinates at which the even occurred. These + coordinates would have to be modified so that unscaled + values were presented to the client. + + + Implementation + + There are many implementation issues, some of which are + similar to the issues involved in implementing the X Video + Extension for DMX. The window contents must be scaled, + either by performing all operations to a frame buffer and + then writing the image to the display (perhaps using + hardware scaling support), or by modifying all of the + various drawing operations to perform scaling. Because of + the complexity involved, the frame buffer option is + recommended. + + + + + + Conclusion and Recommendations + + We recommend a three phase implementation strategy, based on + how an application could be written to take advantage of + scaling: + + + + The XCopyAreaScaled extension should be implemented, since + this is the ideal solution for applications like VNC, and + since making use of this extension will require minimal + changes to applications that already use XPutImage or + XCopyArea. + + + The initial implementation work would include the design + of the X protocol extension, writing this up in the + usual format for extension documentation, implementation + of the protocol transport pieces in XFree86, + implementation of a software fall-back in XFree86 and + DMX, one example hardware implementation for XFree86, + and implementation of support for this extension in DMX. + + + We suggest implementing the extension first on the ATI + Radeon cards. However, since these cards do not provide + a 2D scaled blit primitive, the implementation would + have to make use of the 3D texture engine to emulate a + scaled blit. This is recommended, since other modern + graphics cards also do not provide a simple 2D scaled + blit operation and an example of the more difficult + implementation pathway would be helpful to others. + + + + + Until XCopyAreaScaled is widely supported, applications + that require scaling will have to fall back to another + scaling method. We suggest OpenGL as the first fall-back + method because it is widely available and supported by + DMX. + + + A project centered around OpenGL-based scaling would + implement this scaling in VNC as an example. This work + would include re-writing the vncviewer + rendering engine to cache a master copy of the desktop + image for all operations. + + + + + Since OpenGL is not implemented everywhere, and may not + provide hardware-assisted performance in every + implementation, an application that requires scaling + should also fall back to using the X Video Extension. + + + This project would add support for the X Video Extension + to DMX and would add support to VNC to take advantage of + this extension without introducing artifacts. This + would require modifying the vncviewer rendering + engine to cache a master copy of the desktop image for + all operations. This project should also add support + for the RGB format to at least one XFree86 driver (e.g., + ATI Radeon). + + + The X Video Extension is one of the few popular + extensions that DMX does not support. We recommend + implementing the X Video Extension even if scaling is + the specific goal of that work. + + + + + + We do not recommend implementation of the + XCreateScaledWindow extension because of the complexity + involved. We do not recommend implementation of the + XPutImageScaled extension because it requires the same amount + of work as the XCopyAreaScaled extension, but provides less + functionality. Further, server-side scaling with a large + frame buffer is not recommended because of the + performance implications. + + + The back-end scaling, especially with disconnect/reconnect + support should be explored in the future after + disconnect/reconnect is implemented, but not at the present + time. + + + +
