The library maintains a cache to not reload a file that was previously loaded. In order to still reload an image in case its file would have changed in the meantime, the cache saves the file's modification time. As reported by Coverity (CID #331576) the 'stat' function was not on the execution path the first time an image is loaded, which means the cache information is populated with junk data. This could lead to an image not being reloaded for example. Signed-off-by: Christophe CURIS <christophe.curis@free.fr>
WindowMaker raster graphics library This library is used to manipulate images and convert them to a format that can be displayed through the X window system. Read the wraster.h header for an idea of what is available This Library is LGPL and Copyright (c) Alfredo K. Kojima <kojima@inf.ufrgs.br> The following environment variables control some parameters: RIMAGE_CACHE <integer> Is the maximum number of images to store in the internal cache. Default is 8 RIMAGE_CACHE_SIZE <integer> Is the size of the biggest image to store in the cache. Default is 4k (64x64) Porting ======= It should be fairly easy to port it to other environments (svgalib, libggi etc), probably only requiring wraster.h, context.c and convert.c to be changed. Note that the X specific code should be disabled in that case, including support for libXpm.
