This appendix provides information about graphics classes used by Windows Forms applications.
This section describes the most important graphics namespaces and their most useful classes, structures, and enumerated values.
This namespace defines the most important graphics objects such as Graphics, Pen, Brush, Font, FontFamily, Bitmap, Icon, and Image. The following table describes the namespace’s most useful classes and structures.
|CLASSES AND STRUCTURES||PURPOSE|
|Bitmap||Represents a bitmap image defined by pixel data.|
|Brush||Represents area fill characteristics.|
