From: Michal Krol Date: Fri, 5 Nov 2010 17:54:02 +0000 (+0100) Subject: graw: Export graw_save_surface_to_file(). X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=136ff67ce8a626e628dd76aeb7feba8cf9436cd7;p=mesa.git graw: Export graw_save_surface_to_file(). Allows applications to dump surfaces to file without referencing gallium/auxiliary entry points statically. Existing test apps have been modified such that they save the contents of the fronbuffer only when the `-o' option's specified. --- diff --git a/src/gallium/include/state_tracker/graw.h b/src/gallium/include/state_tracker/graw.h index 6a99b234aa5..8da197f68bf 100644 --- a/src/gallium/include/state_tracker/graw.h +++ b/src/gallium/include/state_tracker/graw.h @@ -71,4 +71,25 @@ PUBLIC void *graw_parse_vertex_shader( struct pipe_context *pipe, PUBLIC void *graw_parse_fragment_shader( struct pipe_context *pipe, const char *text ); +/* Parse a single command-line option, if any.
