Because the library does not have an initialisation function, we need to rely on an automatic called-on-load mechanism, which is provided through a compiler attribute 'constructor'. However, as the project aims to still compile on old hard/software, we include a check in 'configure' to ensure it works, and if not use the legacy solution. Note: Because we introduce a new DEFINE, the 'config.h.in' needs to be regenerated, otherwise you may get a compilation error in wrlib. This is done by re-running './autogen.sh' 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.
