In trying to convert text images (black text on white background) into alpha cutouts as fast as possible, I want to know if there’s any way to tweak the alpha from grayscale feature so that it makes the white parts alpha-transparent and the black parts opaque? It’s so simple that I would think there should be some way (scripted or otherwise) but I have no clue how.
Afaik, you can’t do this with the importer, but you can manually build an alpha channel in your graphics program.
