Sam Lantinga d763a9f64d Fixed bug 2538 - SDL_SetTextureAlphaMod does not work with SDL_FlipMode or rotation in the software renderer 
Adam M.

When setting a texture alpha mod other than 255 and also specifying a flip mode in the software renderer, the rendering fails. When the texture has an alpha channel, it becomes invisible when flipped. When the texture does not have an alpha channel, it is flipped but the colors are wrong: the alpha mod makes the texture darker rather than more translucent.

0) Initialize a software renderer.
1) Load 16-bit 565 or 32-bit texture.
2) Set texture blend mode to BLEND.
3) Set texture alpha mod to 150.
4) Draw the texture flipped horizontally and/or vertically.

VisualC Only use explicit inlining - otherwise Visual Studio 2010 will inline SDL_zero(info) in SDL_vsnprintf() into a memset() call when compiling the Release x64 configuration. 2015-06-14 18:57:05 -07:00

Simple DirectMedia Layer is a cross-platform development library designed
to provide low level access to audio, keyboard, mouse, joystick, and graphics
hardware via OpenGL and Direct3D. It is used by video playback software,
emulators, and popular games including Valve's award winning catalog
and many Humble Bundle games.

More extensive documentation is available in the docs directory, starting
