(...) I just upgraded to Borland C++ Builder 6, and there is a good PNG library for it. I'll use that and convert LPub over to use PNG (instead of BMP and JPG?). Alpha channel will be nice, allowing for semi-transparency. Kevin (20 years ago, 16-Sep-04, to lugnet.cad.dev)

(...) Careful!

(...) I'm not entirely sure, but I'm pretty sure you can create a 32bpp BMP file. Normally, 8 bits in each pixel would then be ignored. However, I don't see any reason the data wouldn't be there for you to interpret yourself. --Travis Cobbs (20 years ago, 15-Sep-04, to lugnet.cad.dev)

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 (...) (20 years ago, 15-Sep-04, to lugnet.cad.dev)

Just a quick question: Is there any programs that can give you a full l3p-check other than l3p?
