- (For those who don't know what XPM is yet, I've appended to this message the
- xpm README file.)
-
- Nothing really important just some fixes.
-
- It is on export.lcs.mit.edu in contrib dir and on avahi.inria.fr in pub/xpm
- dir.
- Here is the changes :
-
-
- 3.2a (92/08/17)
-
- ENHANCEMENTS:
- - use the mock lisp hashing function instead of the gnu emacs one,
- it is faster in some cases and never slower (I've not found any case).
-
- BUGS CORRECTED:
- - function prototypes for ansi compilers.
- - some memory initialization bugs (purify is just great for this).
- - empty strings in extensions are now correctly handled.

- XPM Version 3
-
- WHAT IS XPM?
- ============
-
- XPM (X PixMap) is a format for storing/retrieving X pixmaps to/from files.
-
- Here is provided a library containing a set of four functions, similar to the
- X bitmap functions as defined in the Xlib: XpmCreatePixmapFromData,
- XpmCreateDataFromPixmap, XpmReadFileToPixmap and XpmWriteFileFromPixmap for
- respectively including, storing, reading and writing this format, plus four
- other: XpmCreateImageFromData, XpmCreateDataFromImage, XpmReadFileToImage and
- XpmWriteFileFromImage for working with images instead of pixmaps.
-
- 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.
-
- 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.
