Clipper

Developers who work with the Delphi or C++ programming environments and handle lines and polygons in a spatial environment could benefit from a tool that cold help them perform operations with these objects.

Clipper is a library that was created to offer people an accessible way of performing line and polygon clipping and other spatial operations such as intersections, unions, differences and line/polygon offsetting.

Written in Delphi, C++ and C#, the application is deployed as an archive that contains several demonstration files for each of the above-mentioned programming languages.

This could help novice uses become accustomed with the application’s handling and understand its features and capabilities better.

Some of the application’s features include the capability to accept all types of polygons, including self-extracting ones, support for multiple polygon filling rules (EvenOdd, NonZero, Positive, Negative), numerically robustness, etc.

In addition to its polygon filling features, the application also offers line and polygon offsetting, enabling one to achieve the preferred results in no time.

Those who wish to go even further and enhance the application’s functioning might be happy to know that the deployment package also contains the source code, a Windows CHM help file and the above-mentioned demo applications, which also contain the full source code themselves.
