Back when I used SDL_BlitScaled, it could handle alpha blending just fine.
So does SDL_RenderCopyEx when I’m using a hardware renderer.
However, SDL_RenderCopyEx on a software renderer only works if the source
texture doesn’t have an alpha channel. Otherwise NOTHING gets drawn at all.
SDL version: 2.0.3
BTW…where’s the best place to report bugs? On the mailing list or on
bugzilla?
The Bugzilla is generally the best place to report bugs, but the mailing list is also good for getting help resolving issues and such.
Can you try with the latest SDL 2.0.4 release candidate? https://www.libsdl.org/tmp/download-2.0.php https://www.libsdl.org/tmp/download-2.0.php
Various bugs related to alpha in the software renderer have been fixed in 2.0.4, e.g.:
