An element of ColorAdjustType that specifies the category for which the color-adjustment matrix is cleared.

Return Value

This method does not return a value.

An ImageAttributes object maintains color and grayscale settings for five adjustment categories: default, bitmap, brush, pen, and text. For example, you can specify a color-adjustment matrix for the default category, a different color-adjustment matrix for the bitmap category, and still a different color-adjustment matrix 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, then 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 color-adjustment matrix and a gamma value for the default category. If you set a color-adjustment matrix for the pen category by calling the SetColorMatrix method, the default color-adjustment matrix will not apply to pens. If you later clear the pen color-adjustment matrix by calling the ClearColorMatrix method, the pen category will not revert to the default adjustment matrix; rather, the pen category will have no adjustment matrix. Similarly, the pen category will not revert to the default gamma value; rather, the pen category will have no gamma value.
