GDI+ Reference

Classes

GDI+ provides a rich set of classes for graphics programming. These classes encapsulate various aspects of drawing, image manipulation, text rendering, and more.

Core Graphics Objects

Class Name	Description
Graphics	Represents a drawing surface and provides methods for drawing shapes, images, and text.
Pen	Defines how lines and curves are drawn, including color, width, and style.
Brush	Abstract base class for objects that can fill shapes. Specific brush types include SolidBrush, HatchBrush, TextureBrush, and LinearGradientBrush.
Font	Represents a typeface, style, and size of text.
StringFormat	Specifies layout and formatting information for drawing text, such as alignment and word wrapping.

Image Handling

Class Name	Description
Image	Abstract base class for GDI+ image objects. Derived classes include Bitmap and Metafile.
Bitmap	Represents a raster image. Allows direct pixel access and manipulation.
Metafile	Represents a Windows metafile image.
ImageDecoder	Provides methods to query capabilities of image codecs.
ImageEncoder	Provides methods to query capabilities of image codecs for encoding.

Geometric Shapes and Paths

Class Name	Description
Path	Represents a complex geometric shape consisting of lines, curves, and figures.
PathGradientBrush	Defines a gradient that is defined by a path.
Matrix	Represents a 3x3 matrix used for 2D transformations (translation, rotation, scaling, skewing).

Color and Palettes

Class Name	Description
Color	Represents an ARGB (Alpha, Red, Green, Blue) color.
ColorPalette	Represents a palette of colors for an image.
