SlavaSoft Paint Express is an image editor that I try to use for re-shaping one of my Android app's assets. It takes in a .png file, auto-convertit to .bmp (it can't work with PNG format), I do the reshaping, then save the .bmp file. Re-opening the file in SlavaSoft reveals the image file exactly how I have saved it, however, opening the same file in Photoshop, ABitmapEditor or attempting to convert it to .png via zamzar.com all produce the same erroneous output - they do not show the alpha channel.
Tried using the reshaped asset inside my Android app and the same - no alpha channel. What is going on here ? how come SlavaSoft sees the alpha channel while other tools do not ?
