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.

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!)
