This is an automated email from the git hooks/post-receive script. It was generated because a ref change was pushed to the repository containing the project gfxprim.git. The branch, generate has been updated via 711ed658bc24822ac5d4d08a8eb435352f08036f (commit) via d5456b7fba99b477b44a663264c2fc9fb590e18b (commit) from 944dcb4637c7daa52ce37d6fde1b84b44b412e5a (commit) Those revisions listed above that are new to this repository have not appeared on any other notification email; so we list those revisions in full, below. - Log ----------------------------------------------------------------- http://repo.or.cz/w/gfxprim.git/commit/711ed658bc24822ac5d4d08a8eb435352f08… commit 711ed658bc24822ac5d4d08a8eb435352f08036f Author: Cyril Hrubis <metan(a)ucw.cz> Date: Thu Oct 13 21:10:38 2011 +0200 Generate the *FN_PER_BPP* macros from config too. The GP_DEF_FN_PER_BPP, GP_FN_PER_BPP and GP_FN_RET_PER_BPP are autogenerated accordingly to the gfxprim_config.py. The code is not really nice, but it seems to work for now. Next step is to create WritePixels for 18BPP and test on real HW. diff --git a/include/core/GP_DefFnPerBpp.h b/include/core/GP_DefFnPerBpp.h deleted file mode 100644 index 277c956..0000000 --- a/include/core/GP_DefFnPerBpp.h +++ /dev/null @@ -1,75 +0,0 @@ -/***************************************************************************** - * This file is part of gfxprim library. * - * * - * Gfxprim is free software; you can redistribute it and/or * - * modify it under the terms of the GNU Lesser General Public * - * License as published by the Free Software Foundation; either * - * version 2.1 of the License, or (at your option) any later version. * - * * - * Gfxprim is distributed in the hope that it will be useful, * - * but WITHOUT ANY WARRANTY; without even the implied warranty of * - * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
