Class: IGPImageAttributes




function SetColorMatrix( colorMatrix : TGPColorMatrix, mode : TGPColorMatrixFlags, var type_ : TGPColorAdjustType ) : TGPImageAttributes;

C++ Builder:

TGPImageAttributes __fastcall SetColorMatrix( TGPColorMatrix colorMatrix, TGPColorMatrixFlags mode, TGPColorAdjustType &type_ );

Visual C++ (MFC):

SetColorMatrix(  colorMatrix,  mode,  &type_ );


Sets the color-adjustment matrix for a specified category.


Call this method to set the color-adjustment matrix for a specified category. Remarks An TGPImageAttributes 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- and grayscale-adjustment settings apply to all categories that don't 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- 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 matrix for the pen category by passing ColorAdjustTypePen to the SetColorMatrix method, then none of the default adjustment settings will apply to pens.
