To: sdl@libsdl.org From: Christian Walther <cwalther@gmx.ch> Date: Wed, 21 Dec 2005 13:39:39 +0100 Subject: [SDL] Another mouse bug patch for Mac OS X Oh my, yet another change in the quartz mouse handling code! :) The attached patch fixes the following bug: Calling SDL_WarpMouse() while the cursor is invisible and grabbed should only update SDL's internal mouse location, not try to warp the system cursor (which is not at that location, but fixed in the middle of the window). Otherwise, the next mouse motion event is wrong. Please apply. Thanks Christian

><P
>Get RGB component values from a pixel stored in the specified pixel format.</P
><P
>This function uses the entire 8-bit [0..255] range when converting color
components from pixel formats with less than 8-bits per RGB component
(e.g., a completely white pixel in 16-bit RGB565 format would return
[0xff, 0xff, 0xff] not [0xf8, 0xfc, 0xf8]).</P
