From e2024f47777179382c5d4640cf2e750258906340 Mon Sep 17 00:00:00 2001 From: H.G. Muller Date: Wed, 27 Oct 2010 19:18:41 +0200 Subject: [PATCH] Implement board textures in XBoard The -darkBackTextureFile and -liteBackTextureFile options now wrk in XBoard too, for loading a pixmap that will be used to cut out the dark and light square backgrounds. The cutting algorithm is such that the pixmap image is completely restored if the size was that of the total board (e.g. a drawing of a Xiangqi board). --- xboard.c | 69 +++++++++++++++++++++++++++++++++++++++++++++++++++---------- 1 files changed, 57 insertions(+), 12 deletions(-) diff --git a/xboard.c b/xboard.c index 80e622e..f975e95 100644 --- a/xboard.c +++ b/xboard.c @@ -248,6 +248,7 @@ RETSIGTYPE TermSizeSigHandler P((int sig));
