| // The important language is that when isOpaque is set, opacity is not sampled from the |
| // alpha channel, but blending may still be supported on a transaction via setAlpha. So, |
| // here's the conundrum: |
| // 1. We can't force the SkImage alpha type to kOpaque_SkAlphaType, because it's treated |
| // as an internal hint - composition is undefined when there are alpha bits present. |
| // 2. We can try to lie about the pixel layout, but that only works for RGBA8888 |
| // buffers, i.e., treating them as RGBx8888 instead. But we can't do the same for |
| // RGBA1010102 because RGBx1010102 is not supported as a pixel layout for SkImages. It's |
| // also not clear what to use for F16 either, and lying about the pixel layout is a bit |
| // of a hack anyways. |
| // 3. We can't change the blendmode to src, because while this satisfies the requirement |
| // for ignoring the alpha channel, it doesn't quite satisfy the blending requirement |
| // because src always clobbers the destination content. |
| // |
| // So, what we do here instead is an additive blend mode where we compose the input |
| // image with a solid black. This might need to be reassess if this does not support |
| // FP16 incredibly well, but FP16 end-to-end isn't well supported anyway at the moment. |
