Hey Sam, I have alpha working with RGBA images, but I have not been able to get it to work with getPixels on Grayscale or Lab images ( there are always 1 or 3 channels, never 2 or 4, and pixelFormat is never “GrayscaleAlpha” or “LABAlpha” ) The documentation indicates that it should work. Am I missing something?
On the putPixels side I have managed to create 2 channel Grayscale ImageData with imaging.createImageDataFromBuffer that reports having “GrayscaleAlpha” pixelFormat. It won’t let me putPixels to a background layer and it will to a floating layer, but the alpha data doesn’t seem to be getting applied.
