- GLSL shader wasn't aware of alpha predivide option, always assuming alpha is straight. Gave wrong results when displaying transparent float buffers. - GLSL display wasn't aware of float buffers with number of channels different from 4, crashing when trying to display image with different number of channels. This required a bit larger changes, namely now it's possible to pass format (GL_RGB, GL_RGBAm GL_LUMINANCE) to glaDrawPixelsTex, This also implied adding format to glaDrawPixelsAuto and modifying all places where this functions are called. Now GLSL will handle both 3 and 4 channels buffers, single channel images are handled by CPU. - Replaced hack for render result displaying with a bit different hack. Namely CPU conversion will happen only during render, once render is done GLSL would be used for displaying render result on a screen. This is so because of the way renderer updates parts of the image -- it happens without respect to active render layer in image user. This is harmless because only display buffer is modifying, but this is tricky because we don't have original buffer opened during rendering. One more related fix here was about when rendering multiple layers, wrong image would be displaying when rendering is done. Added a signal to invalidate display buffer once rendering is done (only happens when using multiple layers). This solves issue with wrong buffer stuck on the display when using regular CPU display space transform and if GLSL is available it'll make image displayed with a GLSL shader. - As an additional change, byte buffers now also uses GLSL display transform. So now only dutehr and RGB curves are stoppers for using GLSL for all kind of display transforms. |
