The following table lists some of the important classes and enumerations in theSystem.Drawing.Drawing2D namespace, grouped into categories.

Class category

Details

  • Graphics and Graphics paths

The GraphicsState and GraphicsContainer classes report information about the current Graphics object. GraphicsPath classes represent a series of lines and curves. The GraphicsPathIterator and PathData classes provide detailed information about the contents of a GraphicsPath object.

  • Matrix and transformation related types

The Matrix class represents a matrix for geometric transforms. The MatrixOrder enumeration specifies the order for matrix transformations.

  • Brush classes

The PathGradientBrush and HatchBrush classes enable you to fill shapes with either a gradient, or hatch pattern, respectively.

  • Enumeration related to lines

The LineCap and CustomLineCap enumerations enable you to specify cap styles for a line. The, LineJoin enumeration enables you to specify how two lines are joined in a path. The PenAlignment enumeration enables you specify the alignment of the drawing tip, when you draw a line. The PenType enumeration specifies the pattern a line should be filled with.

  • Enumerations related to filling shapes and paths

The HatchStyle enumeration specifies fill styles for a HatchBrush. The Blend class specifies a blend pattern for a LinearGradientBrush. The FillMode enumeration specifies the fill style for a GraphicsPath.

System_CAPS_cautionCaution

Classes in the System.Drawing.Drawing2D namespace are not supported for use in a Windows or ASP.NET service. Attempting to use these classes in one of these application types may produce unexpected problems, such as diminished service performance and run-time exceptions.
