Alpha premul pipeline cleanup This assumptions are now made: - Internally float buffers are always linear alpha-premul colors - Readers should worry about delivering float buffers with that assumptions. - There's an input image setting to say whether it's stored with straight/premul alpha on the disk. - Byte buffers are now assumed have straight alpha, readers should deliver straight alpha. Some implementation details: - Removed scene's color unpremultiply setting, which was very much confusing and was wrong for default settings. Now all renderers assumes to deliver premultiplied alpha. - IMB_buffer_byte_from_float will now linearize alpha when converting from buffer. - Sequencer's effects were changed to assume bytes have got straight alpha. Most of effects will work with bytes still, however for glow it was more tricky to avoid data loss, so there's a commented out glow implementation which converts byte buffer to floats first, operates on floats and returns bytes back. It's slower and not sure if it should actually be used -- who're using glow on alpha anyway? - Sequencer modifiers should also be working nice with straight bytes now. - GLSL preview will predivide float textures to make nice shading, shading with byte textures worked nice (GLSL was assuming straight alpha). - Blender Internal will set alpha=1 to the whole sky. The same happens in Cycles and there's no way to avoid this -- sky is neither straight nor premul and doesn't fit color pipeline well. - Straight alpha mode for render result was also eliminated. - Conversion to correct alpha need to be done before linearizing float buffer. - TIFF will now load and save files with proper alpha mode setting in file meta data header. - Remove Use Alpha from texture mapping and replaced with image datablock setting. Behaves much more predictable and clear from code point of view and solves possible regressions when non-premultiplied images were used as textures with ignoring alpha channel. |
