Sets the color-adjustment matrix and the grayscale-adjustment matrix for a specified category.

Type: System.Drawing.Imaging.ColorMatrix

The color-adjustment matrix.

Type: System.Drawing.Imaging.ColorMatrix

The grayscale-adjustment matrix.

Type: System.Drawing.Imaging.ColorMatrixFlag

An element of ColorMatrixFlag that specifies the type of image and color that will be affected by the color-adjustment and grayscale-adjustment matrices.

Type: System.Drawing.Imaging.ColorAdjustType

An element of ColorAdjustType that specifies the category for which the color-adjustment and grayscale-adjustment matrices are set.

An ImageAttributes object maintains color and grayscale settings for five adjustment categories: default, bitmap, brush, pen, and text. For example, you can specify adjustment matrices for the default category, different adjustment matrices for the bitmap category, and still different adjustment matrices for the pen category.

The default color-adjustment and grayscale-adjustment settings apply to all categories that do not have adjustment settings of their own. For example, if you never specify any adjustment settings for the pen category, the default settings apply to the pen category.

As soon as you specify a color-adjustment or grayscale-adjustment setting for a certain category, the default adjustment settings no longer apply to that category. For example, suppose you specify a collection of adjustment settings for the default category. If you set the color-adjustment and grayscale-adjustment matrices for the pen category by passing Pen to the SetColorMatrices method, none of the default adjustment settings will apply to pens.
