Malcolm,

FWIW everytime I needed to create a MSK, the MSK just ended up being an all black square. MSK is the same file as BMP with a different extension.

>The complication is that (as I understand things) the BMP contains the image and transparency (white) data and the MSK file contains the data that overrides the white=transparency data with white=white data.

>So its really a two part conversion, first convert the PNG to BMP, then update the BMP converting PNG transparency to white, followed by creating a MSK file containing data for the pixels that need to remain white vs transparent.
