Instead of rewriting -a XPM-parser I managed to port the XPM-library-code to MS-windows. -Thanks to Anaud Le Hors this became a part of the official XPM-library. - -Until now it's only used together with wxWindows. And even there it's more -a kind of beta. But it should be possible to run it as a simple libxpm.a -without wxWindows. - -The key is a transformation of some X types plus some basic X functions. -There is not yet a special MSW-API, so you should know the X types used. - -The following is done in simx.h: - -typedef HDC Display; -typedef COLORREF Pixel; - -typedef struct { - Pixel pixel; - BYTE red, green, blue; -} XColor; - -typedef struct { - HBITMAP bitmap; - unsigned int width; - unsigned int height; - unsigned int depth; -} XImage; - -With these defines and the according functions from simx.c you can call -XPM-functions the way it's done under X windows. It can look like this: - - ErrorStatus=XpmCreateImageFromData(&dc, data, - &ximage,(XImage **)NULL, &xpmAttr); - ms_bitmap = ximage->bitmap; - // releases the malloc,but do not destroy the bitmap - XImageFree(ximage); - -Supported functions are the Xpm*Image* but not the Xpm*Pixmap*. - -DRAWBACKS: -The main drawback is the missing support for Colormaps! There was nothing for -it in wxWindows, so I did not know how to deal with Colormaps. - -The size of the pixmaps is bounded by malloc() (width*height*2 < 64K). - -Close colors do not look that close. But that seems to be the window system. - -Neither a special API for MSW nor a special MSW documentation other than this. -(I can only point you to wxxpm as an example , see below.) - -INSTALLATION: -There is not yet a makefile with it. Simply take all the *.c files -into your project except the files related to Pixmap operations: *P*.c. -!!!You MUST set FOR_MSW on the preprocessor options!!! -(You might uncomment NEED_STRCASECMP in xpm.h if it's in your lib) -This should compile into libxpm.a. Good luck... - -FTP: -wxWindows is currently available from the Artificial Intelligence -Applications Institute (University of Edinburgh) by anonymous FTP. - skye.aiai.ed.ac.uk pub/wxwin/ -or read http://burray.aiai.ed.ac.uk/aiai/aiai.html - -wxxpm, XPM support for wxWindows, the latest version is available at - yoda.cul-ipn.uni-kiel.de pub/wxxpm/ - and maybe in the contrib or tools of wxWindows - -Please contact me if you have suggestions, comments or problems! - -================================================================ -Some fixes and comments by Jan Wielemaker (jan@swi.psy.uva.nl), -Oct 24, 1996: - - * Please try not to disturb me on this, XPM is not my - piece of cake. - - * Hermann Dunkel has appearently moved in virtual space. - -Changes: - - * I've used the xpm package under NT 4.0 and MSVC++ 4.2. - - * I've made a big performance improvement in - ParseAndPutPixels(), fixed creation of the mask in - SetColor() in create.c. I looked into XCreateImage() - in simx.c, but commented out my improvement for reasons - you'll find there. If you know what is going on, statement - (1) does not apply to you. - -Comments on installation: - - * Donot include the to/from pixmap files into the project. - These are the ones containing a capital P somewhere in their - name. You can also first include all, and then remove all - the files you get errors on :-) - - * The DC that is requested should be a valid memory DC, thus - CreateCompatibleDC(NULL) provides a good generic one, but - GetDC(NULL) doesn't! This costed me some time. - - * The real difficulty is using the mask, mostly due to the - bad documentation. If 95 or NT is your target, use: - - MaskBlt(context.hdc, // Destination DC - x, y, w, h, // Destination area - mhdc, // Memory DC with the image selected - sx, sy, // Source X,Y - msk, // HBITMAP of the mask - sx, sy, // Mask X,Y - MAKEROP4(SRCPAINT, SRCCOPY)); // The magic op code. -================================================================ - - --- - ////|\\\\ \\\\\\ Hermann Dunkel - O O ////// IPN Uni Kiel, Germany - | \\\\\\ Tel: +49 431 / 880 3144 - \___/ ////// E-mail: hedu@cul-ipn.uni-kiel.de - \_/ \\\\\\ X.400 : c=de;a=d400;p=uni-kiel;ou=nw-didaktik;s=dunkel - |
