The --alpha option currently covers two related but different concepts: whether or not to ignore the alpha component and possibly blending it with a background. Because of the way the option currently works, it is impossible to have a transparent window (which requires setting --alpha=yes) while blending it with the background at the same time. To solve this, let's rework it so it it superseded by the background option. --background controls what kind of background to set for the image if possible. It can be blended with the set background color, with tiles, or not blended at all (the last one is still broken on X11/mesa except for GLX, *sigh*). In this new paradigm, --alpha=no has no real purpose because you can simply set the background to color and whatever color you want for exactly the same effect. So the option is removed. Instead, the hint set by windowing backends (i.e. setting ra_ctx->opts.want_alpha) can by done with the --background option. As an aside, the colors in vo_gpu are currently bugged due to not pre-multiplying the alpha and it seems no one ever noticed. The next commit fixes that. vo_gpu_next support happens latter since it requires new things from libplacebo. Fixes #9615. |
