libXpm - X Pixmap (XPM) image file format library ------------------------------------------------- All questions regarding this software should be directed at the Xorg mailing list: https://lists.x.org/mailman/listinfo/xorg The primary development code repository can be found at: https://gitlab.freedesktop.org/xorg/lib/libXpm Please submit bug reports and requests to merge patches there. For patch submission instructions, see: https://www.x.org/wiki/Development/Documentation/SubmittingPatches ------------------------------------------------------------------------------ libXpm supports two optional features to handle compressed pixmap files. --enable-open-zfile makes libXpm recognize file names ending in .Z and .gz and open a pipe to the appropriate command to compress the file when writing and uncompress the file when reading. This is enabled by default on platforms other than MinGW and can be disabled by passing the --disable-open-zfile flag to the configure script. --enable-stat-zfile make libXpm search for a file name with .Z or .gz added if it can't find the file it was asked to open. It relies on the --enable-open-zfile feature to open the file, and is enabled by default when --enable-open-zfile is enabled, and can be disabled by passing the --disable-stat-zfile flag to the configure script. All of these commands will be executed with whatever userid & privileges the function is called with, relying on the caller to ensure the correct euid, egid, etc. are set before calling. To reduce risk, the paths to these commands are now set at configure time to the first version found in the PATH used to run configure, and do not depend on the PATH environment variable set at runtime. To specify paths to be used for these commands instead of searching $PATH, pass the XPM_PATH_COMPRESS, XPM_PATH_UNCOMPRESS, and XPM_PATH_GZIP variables to the configure command.
