(...) If you're interested, LDView has two C++ classes that together allow you to write a PNG via libpng. They have the advantage of being much easier to use that libpng itself. Take a look in the LDView source at TCImage.{h,cpp} and (...) (20 years ago, 16-Sep-04, to lugnet.cad.dev)

(...) 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 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').
