I previously asked "How to Batch Export All Directory Contents to PNG-8, Overwriting Existing Files?". The answer I received appears to be technically correct. But I forgot to mention one serious criteria -- my image has partial transparency.
Hence if my test image is:
Quick Export to png-8 or
png-8) produces a beautifully visually equivalent file:
Layers to Files and
Save For Web (Legacy) produce the image seen on the right (image on left is original):
My issue is that most of my images I'm trying to export via
Actions rely on partial transparency. But the only two export to
png-8 options I can find that seem to support partial transparency aren't currently supported by actions.
I get the
Save for Web one, as per the hard edges motivation Adobe elaborates upon here. I don't understand as well why the layer export is also doing matteing on partial transparency, with no hint of this in the dialog (maybe a bug?) and w/ no way to even pick the matte color, for that matter (the automatically selected matteing is
#ffffff in the color space of some of the content).
Are there any other ways to export to
png-8, w/ partial transparency OTHER than
Export as and
Quick Export to png-8?
