XPM (X PixMap) is a format for storing/retrieving X pixmaps to/from files.
libxpm-3.4k: description + notes
Here is provided a library containing a set of four functions, similar to the X bitmap functions as defined in the Xlib:
XpmCreatePixmapFromData,XpmCreateDataFromPixmap,XpmReadFileToPixmapandXpmCreateImageFromData,XpmCreateDataFromImage,XpmWriteFileFromImagefor 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 details.
NOTE: Developers intending to use this distribution of libxpm for application development should be sure to read the information below. Users installing libxpm for the runtime environment only need not read any further.
Developers intending to use this library for development of other freeware packages or their own software applications will need to be familiar with a few peculiarities due to the way that this library is packaged and installed. The reasons for this installation strategy are described further in the fw_common product release notes.
The header files and libraries in this package are installed into /usr/freeware. This means that when building software using this distribution of libxpm you should be sure to do the following:
This flag will cause your compilations to correctly find the library's header files at compile time.
- Include the following flag on your compile lines:
- -I/usr/freeware/include
Include the following flag on your link lines:
-L/usr/freeware/lib (if using o32 ABI) -L/usr/freeware/lib32 (if using n32 ABI) -L/usr/freeware/lib64 (if using 64 ABI) This flag will cause the linker to correctly find the library's archive or shared object files at link time.
Additionally, include the following flag on your link lines:
-rpath /usr/freeware/lib (if using o32 ABI) -rpath /usr/freeware/lib32 (if using n32 ABI) -rpath /usr/freeware/lib64 (if using 64 ABI) This flag will allow the binary to locate the shared object library files when the application is run. This is required since the shared objects are stored in these /usr/freeware subdirectories which are not searched by the run-time linker by default.
Finally, if you are building an installable package for inst (contributing to freeware, for example) be sure to make your package depend upon this package. Add the following line to your spec file: prereq ( fw_libxpm.sw.lib 1230000000 1239999900 ) Following these guidelines will allow your application to safely and easily use the software in this package.
