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. + +See the XPM Manual for more details. + +HOW TO GET XPM? +=============== + +New xpm updates are announced on the comp.windows.x newsgroup, and on the +"xpm-talk" list. All new "official" xpm releases can be found by ftp on: + + export.lcs.mit.edu (18.30.0.238) contrib (Boston, USA) + avahi.inria.fr (192.5.60.47) pub (Sophia Antipolis, France) + + +DOCUMENTATION: +============= + +Old users might read the CHANGES file for a history of changes interesting +the user. + +Read the docs (xpm.tex is the manual in LaTeX form). The documentation is in +LaTeX format (IMPORTANT: see the Makefile to know how to print it. The LaTeX +source should work with most dvi2ps or dvips programs. I use myself Tomas +Rokicki's dvips v5.0 that you can get by anonymous ftp on +labrea.stanford.edu). We can mail you a PostScript version of the +documentation if you are not able to print it, or you can grab one on the ftp +servers. + +INSTALLATION: +============ + +To obtain the XPM library, first uncompress and untar the compressed tar file +in an approriate directory. + +Then you can either compile xpm via "imake" or in a stand-alone way. + +WITH IMAKE: + + The Imakefile is provided. You should know how to use imake to build + the XPM Makefile, by executing "xmkmf" then do: + + make depend + make + + which will build the XPM library and sxpm application. + Then do: + + make install + make install.man + + which will install the library and the sxpm man page. + + If it fails, you may edit the Imakefile to add compilation flags to + suit your machine. + +WITHOUT IMAKE: + + To compile xpm, in the xpm directory you just created, do: + + make -f Makefile.noXtree + + Then to install it, do: + + make -f Makefile.noXtree install + +NOTE: if you compile with gcc, use "gcc -traditional", otherwise you will + have compilation warnings (but the code will work Ok) + +SXPM: +==== + +In addition to the library the sxpm tool is provided to show XPM file and +convert them from XPM2 to XPM version 3. If you have previously done 'make' or +'make all' you should have it yet, otherwise just do: + + make sxpm + +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 + +By executing 'sxpm' without any option you will get the usage. + +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. + +Executing 'sxpm -plaid -s lines_in_mix blue' will show the feature of +overriding color symbols giving a colorname, and executing 'sxpm -p +lines_in_mix 1' will show overriding giving pixel value. + +Then you should try 'sxpm -plaid -o output' to get an output file using the +XpmWriteFileFromPixmap function. + +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. + +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. + +The XpmCreatePixmapFromData function is on purpose called without any Xpminfo +pointer 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'. + +To end look at plaid_ext.xpm and try "sxpm -nod plaid_ext.xpm -v" to see how +extensions are handled. + +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 XPM2 to a +XPM version 3 using sxpm. + +See the manual page for more detail. + +CONVERTERS: +========== + +In the converters directory you can find different converters about XPM. +There is a perl script xpm1to3.pl to convert XPM1 format file to XPM version +3. And there are files to build the converters ppmtoxpm and xpmtoppm; to get +instructions about how to build them you should read the corresponding +ppm.README file. + +KNOWN BUG: +========= + +If two symbols get the same color pixel when reading a pixmap, one will be +lost when writting it out. + +DISCUSSION: +========== + +There is a mailing list to discuss about XPM which is xpm-talk@sophia.inria.fr. +Any request to subscribe should be sent to xpm-talk-request@sophia.inria.fr. + +COPYRIGHT: +========== + + Copyright 1990-92 GROUPE BULL -- + See license conditions in the COPYRIGHT file of the XPM distribution + +Please mail any bug reports or modifications done, comments, suggestions, +requests for updates or patches to port on another machine to: + +lehors@sophia.inria.fr (INTERNET) + +33 (FRANCE) 93.65.77.71 (VOICE PHONE) + +Arnaud Le Hors (SURFACE MAIL) +Bull c/o Inria BP. 109 +2004, Route des lucioles +Sophia Antipolis +06561 Valbonne Cedex +FRANCE |
