I want to create an image by code within a console mode program (actually a
CGI program) written with Kylix. How can I do that ? It looks like the
bitmap object works only within GUI application, making use of QT.

btw: I have a Delphi/Win32 version that works perfectly. I want to port this
code as much as possible.

You can build a .bmp writing header and data.
Also you can take a look to libpng, but it's for C language only, you need
to translate...

Thank you for the link.
Unfortunately, it is not a good solution for a CGI. I doubt that a hosting
company will appreciate to install QT and xvfb on their webservers.

You might try GD:

If you're interested, I think I have some delphi code to show how to use it.

This is for reading a PNG file.
I'm looking a library to create images, that is draw pixels, lines, text.
Same capabilities as TBitMap.Canvas.

Theo provided a link to GD which seems to be what I'm looking for

Yes, of course. I can also write a new compiler and why not a new OS !

Ask François, I'm sure he has an updated/improved version.
