Subject: [SDL] SetAlpha silently fails without error for SDL_DisplayFormatAlpha

Hi,

SetAlpha silently fails without error if the surface was created with
SDL_DisplayFormatAlpha() instead of SDL_DisplayFormat(). This should be
documented or at least return an error code.

Setting Sam as "QA Contact" on all bugs (even resolved ones) so he'll definitely be in the loop to any further discussion here about SDL.

--ryan.
Comment 2 Sam Lantinga 2006-03-20 01:37:47 UTC 
This is fixed in CVS:
The palette -> RGBA blit wasn't following the rule:
 * RGB->RGBA:
 *     SDL_SRCALPHA not set:
 *      copy RGB, set destination alpha to source per-surface alpha value.

Please reopen this bug if there are any other cases that aren't working correctly.
