Has anybody been able to get alpha data for a grayscale image? hasAlpha is always false and there is only one component. With RGB, if there is alpha I get 4 components and hasAlpha is true. PhotoshopImageData says it supports “GrayscaleAlpha” but maybe it is just not implemented?
Maybe @jsbache could know if/how grayscale with alpha is supported?
Same issue here, was anyone able to figure it out?
