Is it possible to set alpha transparency of some area of the image in 32-bit color mode?

Hi, I am trying to convert from EPS to PNG with transparent background. The transparent color should be white 255. In Options > Write > PNG I set 255 and in Read I check the Compose image with transparency. Unfortunately I still cant receive the PNGs with transparent background. Any ideas? Thank you

Welcome to the forum, Gitchev (-:

Did you reduce the color depth of the converted file prior to saving it?
