Graphics Class Properties

The Graphics class provides a long list of properties (see Table 3.1) and methods. We will discuss and use these properties and methods in this and following chapters.

Table 3.1. Graphics properties

Property

Description

Clip

Gets and sets a Region type that limits the drawing region of the Graphics object.

ClipBounds

Returns a RectangleF structure that bounds the clipping region of this Graphics object. Supports read-only access.

CompositingMode

Returns a value of type CompositingMode enumeration representing how composite images are drawn to the Graphics object.

CompositingQuality

Gets and sets the rendering quality (directly proportional to the visual quality of the output and inversely proportional to the rendering time) of composite images, represented by the CompositingQuality enumeration.

DpiX

Returns the horizontal resolution (dots per inch) of a Graphics object.

DpiY

Returns the vertical resolution (dots per inch) of a Graphics object.

InterpolationMode

Gets and sets the interpolation mode (which determines intermediate values between two endpoints), represented by the InterpolationMode enumerator.

IsClipEmpty

Returns a value indicating whether the clipping region of a Graphics object is empty. When there is no clipping, this property returns false.

IsVisibleClipEmpty

Returns a value indicating whether the visible clipping region of a Graphics object is empty.

PageScale

Gets and sets a value for scaling between world units and page units for this Graphics object.

PageUnit

Gets and sets a value that represents the unit of measure for page coordinates.

PixelOffsetMode

Gets and sets a value for the pixel offset mode (PixelOffsetMode enumeration).

RenderingOrigin

Represents the rendering origin of a Graphics object for dithering and hatch brushes.

SmoothingMode

Gets and sets the smoothing mode of a Graphics object (SmoothingMode enumeration). Does not affect text. Smoothing modes include high quality, high speed, and anti-aliasing.

TextContrast

Gets and sets the gamma correction value for rendering anti-aliased and ClearType text values, ranging from 0 to 12. The default is 4.

TextRenderingHint

Gets and sets the text rendering quality (TextRenderingHint enumeration). Affects only text drawn on the Graphics object.

Transform

Gets and sets the world transformation matrix (transformation is the process of converting graphics objects from one state to another). The transformation state is represented by a transformation matrix.

VisibleClipBounds

Gets and sets the visible clipping region of the Graphics object (the intersection of the clipping region of the Graphics object and the clipping region of the window).
