Below is the lists of GDI+ namespaces:

• System.Drawing. It namespace provides access to GDI+ basic graphics functionality.

• System.Drawing.Drawing2D. It namespace provide advanced two-dimensional and vector graphics functionality.

• System.Drawing.Imaging. It namespace provides advanced GDI+ imaging functionality.

• System.Drawing.Text. It namespace provides advanced GDI+ typography functionality.

• System.Drawing.Printing. It namespace provides print-related services.

Graphics Categories

Using GDI+ you can work with three categories of graphics:

1. Two-dimensional (2D) vector graphics, such as lines, curves, and figures that are specified by sets of points on a coordinate system.
