(...) 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)

(...) LPub is written in Borland C++ Builder, which is the C++ version of Delphi. The programing language is different, but the libraries are the same. I'd like Alpha channel, instead of binary bitmap, because it might provide some help with (...) (20 years ago, 16-Sep-04, to lugnet.cad.dev)

(...) 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 (...)

(...) Careful! A *Windows* color value uses the high bit to indicate that the rest is an index into the 'System Color Palette' and not a RGB value at all (In Delphi you have ColorToRGB() to get the RGB value from such a 'color').

(...) 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)

Thanks guys, I believed there had to be some kind of easy fix to the problem (too stupid). Now I feel a lot more comfortable certifying parts! -NB (20 years ago, 12-Sep-04, to lugnet.cad.dev, FTX)
