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).
