• bug 915001 - [B2G][Helix][gallery][yangshiqi]can not save the edited picture(>1M) /Jerry
  • I only disable the z and stencil test for the 3D canvas. Thus, we can use the original code path to handle 5M pixel image. The feedback of this wip is not good. We might have OOM problem when we handle 8M or more pixel image. Vlad suggest that we should divide the image into several parts and process them independently. It might have some problem when we have another image effect in the future especially some larger kernel post effect(ex. blur, bloom).
