How do I convert my images to or from XPM ?</a></h2> -<p> - Netpbm is surely the best image conversion package that I know of. It defines - formats for color, gray and monochrome images and provides a set of filters. - Thus a GIF image can be converted to XPM with something like: -<p> - $ giftoppm youricon.gif | ppmtoxpm > youricon.xpm -<p> - The latest release can be found at least from wuarchive.wustl.edu - (128.252.135.4), directory /graphics/graphics/packages/NetPBM - - -<h2><a name="Q2">2. Why are my XPM files said to be invalid ?</a></h2> -<p> - There are three official versions of the XPM format. The XPM library since - version 3.3 can read all them but writes out only XPM 3. Also the small - program called sxpm which is part of the XPM library package can be used to - automatically translate XPM 1 and 2 files to XPM 3 with a command such as: -<p> - $ sxpm -nod yourxpm1or2file -o yourxpm3file -<p> - Also, the XPM format defines "None" to be the color name meaning - "transparent", but IXI used to hack the XPM library in its early days to - handle transparency as "#Transparent". This makes IXI format not compatible - with the official XPM format, and so not readable neither by the official XPM - library nor any of the programs built on top of it. -<p> - The only solutions are either to stick on IXI programs which can deal with - their format or convert your files to the standard XPM format. This can be - done simply by changing "#Transparent" to "None". - - -<h2><a name="Q3">3. Why does my program core dumps using XPM ?</a></h2> -<p> - Be sure the XpmAttributes structure you pass by reference has a valid - valuemask. You can give NULL instead if you don't want to use an - XpmAttributes but if you do, you MUST initialize its valuemask component to - some valid value, at least 0, otherwise unpredictable errors can occur. -<p> - So instead of doing something like: -<pre> - XpmAttributes attrib; - - XpmReadFileToPixmap(dpy, d, filename, &pixmap, &mask, &attrib); -</pre> -<p> - you should do: -<pre> - XpmAttributes attrib; - - attrib.valuemask = 0; - XpmReadFileToPixmap(dpy, d, filename, &pixmap, &mask, &attrib); -</pre> - - -<h2><a name="Q4">4. Why does my program core dumps using XPM with a widget ?</a></h2> -<ul> -<li>First the XPM library is Xlib level, so don't pass your widget as a - Drawable parameter. A Drawable is either a Window or a Pixmap. The widget's - window can do the job but: - -<li>Then a widget only gets a Window when realized, so passing XtWindow(widget) - with a not yet realized widget is wrong. Either realize you widget first or - use another window. Since the Drawable parameter is only used to specify - the screen to which the pixmap must be created on, most of the time the - default root window is just fine. -</ul> - - -<h2><a name="Q5">5. How can I get a non rectangular icon using XPM ?</a></h2> -<p> - The X Window System does not support transparent color. However there are - several ways you can use to get the same visual effect using XPM: -<ul> -<li>First you can use the None color to get a shape mask and use it as - explained below (question 7). - -<li>Second you can define a symbolic color name such as "mask" in the XPM - format file, then use the color overriding mechanism to set this symbolic - color to the color of the underlying object. Note that in this case the XPM - library won't create a shape mask, and that if the color of the underlying - object is changed then you'll have to create a new pixmap. -</ul> - - -<h2><a name="Q6">6. What exactly triggers the creation of a mask when using XPM ?</a></h2> -<p> - Basically a mask is created if "None" is used as one of the color of the - pixmap. Be aware that this is not only true if it is used in the XPM of the - pixmap since the colors can be overridden at load time. So a mask is created - if the "None" color is used at load time, coming either from the XPM - definition or the color overriding. - - -<h2><a name="Q7">7. How should I use the mask ?</a></h2> -<p> - There are basically two ways of using the mask: -<ul> -<li>Use the mask as a shapemask with the X11 Nonrectangular Saphe Window - Extension. Typically this is what should be done when the icon is used in a - desktop. - -<li>Use the mask as a clipmask in the GC you pass to XCopyArea when drawing the - pixmap. So the "transparent" pixels being not actually drawn will get the - underlying pixels colors. -</ul> - - -<h2><a name="Q8">8. Is there a string to pixmap converter for Motif ?</a></h2> -<p> - Yes, Motif 2.0 or later does support XPM pixmaps as well as XBM bitmaps. - - -<h2><a name="Q9">9. How can I edit XPM icons ?</a></h2> -<p> - As listed below several editors either commercial or not are supporting the - XPM format. However, pixmap is the one I would recommend since it is freely - available and, being fully dedicated to XPM, it allows to edit all the - special things, such as the symbolic color names, which makes XPM different - from all the other image formats. Pixmap can always be found by ftp from - ftp.x.org (contrib) and avahi.inria.fr (pub/pixmap). -<p> -Last Update: 3 August 1994 -<table border=1> -<caption>XPM Icon Editors</caption> -<tr><th>Program<th>Infos<th>Source/Author<th>Platforms<th>SA<th>XPM<th>cost -<tr><td>pixmap<td><ul> - <li><a href="ftp://ftp.x.org/contrib/application/pixmap/pixmap2.6.tar.gz">ftp://ftp.x.org/contrib/application/pixmap/pixmap2.6.tar.gz</a> - <li>requires 3.4 or higher revision of Xpm lib. - <li>supports all XPM format features - <li>current version doesn't work on 24-plane displays -</ul> -<td>Lionel Mallet<td>source<td>yes<td>3<td>NC - -<tr><td>pixt<td><ul> - <li><a href="ftp://ftp.x.org/contrib/pixt.tar.Z">ftp://ftp.x.org/contrib/pixt.tar.Z</a> - <li>doesn't work on 24-plane displays - <li>last updated November 1991 -</ul> -<td>J.

Is there a collection of icons somewhere ?</a></h2> -<p> - At least there is one freely available: Anthony's X Icon Library. You can - found it on several ftp servers, such as <a href="ftp://server.berkeley.edu/pub/AIcons">server.berkeley.edu/pub/AIcons</a>. It - contains only small icons (less than about 100x100 pixels in size) which are - stored in groups in a logical way. Color icons are stored in XPM format and - Black & White icons in XBM. - - -<h2><a name="Q11">11. The documentation fails to print out. Why ?</a></h2> -<p> - The PostScript documentation file is formatted for US letter paper. Frame - Maker tries very hard to ensure that you have the right paper and punts if - you don't. However, you can easily work around this problem by applying the - following patch. If for some reason applying the patch fails, you can still - do it by hand. Just locate the corresponding block in the PS file and remove - the lines with a leading '-' character. - By the way, this applies to any doc generated by Frame Maker. The - corresponding block might be slightly different depending on which version of - Frame Maker was used, but it is still easy to locate. - -<pre> -*** xpm.PS Wed Sep 11 15:47:43 1996 ---- xpm-A4.PS Thu Nov 21 09:27:28 1996 -*************** -*** 647,668 **** - 0 ne /edown exch def - /yscale exch def - /xscale exch def -- FMLevel1 { -- manualfeed {setmanualfeed} if -- /FMdicttop countdictstack 1 add def -- /FMoptop count def -- setpapername -- manualfeed {true} {papersize} ifelse -- {manualpapersize} {false} ifelse -- {desperatepapersize} {false} ifelse -- { (Can't select requested paper size for Frame print job!)
