What Is XPM?</a></h2> +<p> +XPM (X PixMap) is a format for storing/retrieving X pixmaps to/from files. +<p> +Here is provided a library containing a set of four functions, similar to the +X bitmap functions as defined in the Xlib: <code>XpmCreatePixmapFromData</code>, +<code>XpmCreateDataFromPixmap</code>, <code>XpmReadFileToPixmap</code> and <code>XpmWriteFileFromPixmap</code> for +respectively including, storing, reading and writing this format, plus four +other: <code>XpmCreateImageFromData</code>, <code>XpmCreateDataFromImage</code>, <code>XpmReadFileToImage</code> and +<code>XpmWriteFileFromImage</code> for working with images instead of pixmaps. +<p> +This new version provides a C includable format, defaults for different types +of display: monochrome/color/grayscale, hotspot coordinates and symbol names +for colors for overriding default colors when creating the pixmap. It provides +a mechanism for storing information while reading a file which is re-used +while writing. This way comments, default colors and symbol names aren't lost. +It also handles "transparent pixels" by returning a shape mask in addition to +the created pixmap. +<p> +See the XPM Manual for details. + + +<h2><a name="sec2">2. Where to get XPM?</a></h2> +<p> +New XPM updates are announced on the comp.windows.x newsgroup, and on the +"xpm-talk" list and you can always consult the XPM Home page at <a +href="http://www.inria.fr/koala/lehors/xpm.html">http://www.inria.fr/koala/lehors/xpm.html</a> +<p>The latest "official" XPM release can always be found at: +<br>Boston, USA: <a +href="ftp://ftp.x.org/contrib">ftp://ftp.x.org/contrib</a> +<br>Sophia Antipolis, France: <a +href="ftp://koala.inria.fr/pub/xpm">ftp://koala.inria.fr/pub/xpm</a> + + +<h2><a name="sec3">3. Documentation</a></h2> +<p> +Old users might read the <a href="CHANGES">CHANGES</a> file for a history +of changes interesting the user. +<p> +Read the doc. The documentation is in PostScript format (<a +href="doc/xpm.PS">doc/xpm.PS</a>) and has been produced with +FrameMaker. The source files are available on request. +<p> +A <a href="FAQ.html">FAQ</a> (Frequently Asked Questions) is also provided, +so if you experience any problem you should have a look at this file. + + +<h2><a name="sec4">4. Installation</a></h2> +<p> +To obtain the XPM library, first uncompress and untar the compressed tar file +in an appropriate directory. +<p> +Then you can either compile XPM via "imake" or in a stand-alone way. + +<h3><a name="sec4.1">4.1. With imake</a></h3> +<p> + Imakefiles are provided to build both shared and unshared libraries. + However, building a shared lib is very OS dependent and often requires + specific files which are not available. Also config files are often not + set correctly for this task. So if it fails you can avoid trying to + build one and simply build the static library instead. In order to do + so you should edit the top Imakefile to add -DSharedLibXpm=NO to the + definition of IMAKE_DEFINES as described. +<p> + The compilation and installation of the library and the sxpm program + should only require you to edit the top Imakefile. But you should do so + in order to specify the locations where the various files should be + installed and to set the DEFINES variable accordingly to your system. +<p> + On Solaris 2.* the compilation works only in the native svr4 + environment, avoid the bsd one or it won't compile. Especially you + should be using /opt/SUNWspro/bin/cc and not /usr/ucb/cc. + Also since the compiler is no longer part of the OS distribution a lot + of people use gcc instead. This is fine, but be aware that the imake + tool you get as part of the X Window System on a solaris box is + configured for cc. Therefore the compilation using the generated + Makefiles will not succeed unless you have changed the default + configuration. An easy work around is to directly edit the generated + lib/Makefile to change '-K pic' to '-fpic'. Fixing your imake + configuration would be better though. +<p> + On Linux, if you do not use ELF yet you'd better get the binary + distribution available from sunsite. Because it's really a pain to + build a shared lib and the current XPM distribution doesn't contain + the jump files you would need to do so. On the other hand people have + had no problems building it using ELF. +<p> + Then execute the following command: +<pre> + xmkmf -a +</pre> +<p> + or if this option is not supported by your version of xmkmf: +<pre> + xmkmf + make Makefiles + make includes + make depend (optional) +</pre> +<p> + Then simply execute: +<pre> + make +</pre> +<p> + which will build the XPM library and the sxpm application. + Then do: +<pre> + make install + make install.man +</pre> +<p> + which will install the library and the sxpm program and man page. +<p> + If it fails, be sure you have set the DEFINES correctly in the top + Imakefile to suit your machine. + +<h4>NOTE ON USING IMAKE:</h4> +<p> + Building the XPM distribution with imake requires to have imake + <strong>correctly installed and configured</strong> on your + system. I do my best at tweaking the Imakefiles so they work with + as many imake flavors people might have as possible but there is + nothing I can do against wrong imake configurations. So if your + build fails using imake, don't send me email for advice. Get your + imake configuration fixed or forget about it! + + +<h3><a name="sec4.2">4.2. Without imake</a></h3> +<p> + A set of makefiles is provided for those who do not have imake + available on their system. However, this is only provided as a + convenience and you should be considered as a starting point and not as + something ready to use. These makefiles, called Makefile.noX, will most + likely require some editing in order be set accordingly to your system. +<p> + Once this setting is done, you should be able to compile XPM, by + executing the following command: +<pre> + make -f Makefile.noX +</pre> +<p> + Then to install it, do: +<pre> + make -f Makefile.noX install +</pre> + + +<h2><a name="sec5">5. SXPM</a></h2> +<p> +In addition to the library the sxpm tool is provided to show XPM file and +convert them from XPM1 or XPM2 to XPM version 3. If you have previously done +'make' or 'make all' you should already have it, otherwise just do: +<pre> + cd sxpm; make +</pre> +<p> +This application shows you most of the features of XPM and its source can be +used to quickly see how to use the provided functions. +<p> +By executing 'sxpm -help' you will get the usage. +<p> +Executing 'sxpm -plaid' will show a demo of the XpmCreatePixmapFromData +function. The pixmap is created from the static variable plaid defined in the +sxpm.c file. sxpm will end when you press the key 'q' in the created window. +<p> +Executing 'sxpm -plaid -sc lines_in_mix blue' will show the feature of +overriding color symbols giving a colorname, executing 'sxpm -plaid -sp +lines_in_mix 1' will show overriding giving a pixel value, and executing 'sxpm +-plaid -cp red 0' will show overriding giving a color value. +<p> +Then you should try 'sxpm -plaid -o output' to get an output file using the +XpmWriteFileFromPixmap function. +<p> +You can now try 'sxpm -plaid -o - -nod -rgb /usr/lib/X11/rgb.txt' to directly +get the pixmap printed out on the standard output with colornames instead of +rgb values. +<p> +Then you should try 'sxpm plaid.xpm' to use the XpmReadFileToPixmap function, +and 'cat plaid_mask.xpm|sxpm' to see how "transparent pixels" are handled. +<p> +The XpmCreatePixmapFromData function is on purpose called without any XpmInfos +flag to show the utility of this one. Indeed, compare the color section of the +two files foo and bar obtained from 'sxpm -nod -plaid -o foo' and 'sxpm -nod +plaid.xpm -o bar'. All the default colors and also the comments have been +restored. +<p> +To end look at plaid_ext.xpm and try "sxpm -nod plaid_ext.xpm -v" to see how +extensions are handled. +<p> +Of course, other combinations are allowed and should be tried. Thus, 'sxpm +plaid.xpm -o output -nod' will show you how to convert a file from XPM1 or XPM2 +to a XPM version 3 using sxpm. +<p> +See the manual page for more detail. + + +<h2><a name="sec6">6. CXPM</a></h2> +<p> +The cxpm tool is provided to help you figure out whether an XPM file is correct +or not with regard to its format. If you have previously done 'make' or +'make all' you should already have it, otherwise just do: +<pre> + cd cxpm; make +</pre> +<p> +The related man page will tell you everything about it but here is a simple +example of what it does: +<pre> +$ ./cxpm bogus_pixmap +Xpm Error: Invalid XPM file. +Error found line 3 near character 5 +</pre> +<p> +It is pretty limited but at least, unlike sxpm, it gives you some hint on where +the error occured within the file. + + +<h2><a name="sec7">7. Other Tools</a></h2> +<p> +Several converters dealing with XPM and a pixmap editor can be found in the +xpm-contrib distribution. Also I recommend the use of netpbm to do any kind of +general image operations such as scaling, resizing, dithering, and to convert +from and to any other image format. + +<h2><a name="sec8">8.
