I added mask generation for assembly images into LPub. It now can generate a
specific mask for each assembly image. I plan on using this for the layout
process, where you provide a backdrop image for a page, and LPub uses a mask to
superimpose the assembly on some nice background image. You get a separate
bitmap file that contains the mask. Is there some way of merging the masks in
with the original assembly image? I'm sure there is for file formats like PNG,
but LPub does not know how to deal with PNG yet.
The layout process would start with the background image you provide, overlay it
with the assembly image, then overlay the part list image and step number (maybe
page number too.)
Willy has been the most vocal one about having masks. Willy, how did you see
the masks getting implemented?

| (...) LPub is written in Delphi, if I'm not misremembering? Have you looked at (URL) can't say I understand all of the code at a quick glance, but it looks like all you have to do is setting the Alpha channel to a suitable value for every pixel, and (...)
