same issue for weeks

@KeitelDOG Thanks for your answer:) I'v struggled weeks for this library. There are too many complex issues and fewer documents. I've just gave up it and try to make a...

@KeitelDOG , I've already done the python bridge by `child_process`. My task is to scan fillmarks and clip answer areas from an exam sheet, the image size is just the...

There's no designed api for this too. One possible way: Create a `SnapshotTarget` by yourself, and call the `renderSelf(on:)` method of the elements witch you want, then you can take...

@ViaJables Yes, It's a bug. The logic about opacity is a bit messy, I'm trying to resolve this.

@ViaJables try the new 2.8.0 release, different brush sizes will have similar opacity now

Current solution is simple and not perfect, your situation is one of the side effect. It seems that the low opacity effects the rbg value passing to Metal, I'm not...

Yes, because the difference of brush size will cause the overlapping of textures change, so the actual opacity set to the texture should be calculated from the user specified alpha,...

大概看了下 Demo，要通过 Metal 实现类似功能的话，原理和思路上应该是相近的，不过实现细节应该会不太一样。可能能做 MaLiang 3.0 的时候会考虑增加类似功能吧。不过 3.0 目前还在设想阶段，还没有具体的计划。

确实有问题，应该是之前改透明度问题造成的...
