Graphics32 is a rich, high-performance 32bits graphics library for Delphi, with extensive capability. This showcase was submitted by Christian-W Budde, who is an active contributor to the Graphics32 project.
This is an interactive demo/testing tool where you can write GR32 code and immediately see its output.
This can help develop complex graphics from code. While writing the manual this comes very handsome, because previously we coded everything in Delphi with a lot of trial and error, which involves compilation and execution.
Now, both steps are performed in background and all you need to do is to inspect, whether the output is sufficient.
This tool is currently a work in progress, you can download a (not so recent) GR32_DWS executable version here (7zip, 1048 kB).
