• Converting Bézier paths into vector paths. • Sorting vector paths into svp's. • Antialiased rendering of svp's. • Computation of stroke paths (with line cap and join options). • Intersection, union, and difference of svp's. • Finding covering uta's for rectangles, vector paths, and svp's. • Union of uta's. • Decomposition of uta's into minimal set of rectangles. • Alpha-compositing. • Affine transformation of paths and images.

* GD can create images Consists of lines, arcs, text (using program-selected fonts), and various of colors. support for truecolor images, alpha channels, resampling, etc. * GD supports Variety of programming languages. * GD Widely used PHP.
