(...) 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)

(...) Careful!
