Summary
Interface to a TGPImageAttributes object.
Description
Defines interface to a TGPImageAttributes object.
An TGPImageAttributes object contains information about how bitmap and metafile colors are manipulated during rendering. An TGPImageAttributes object maintains several color-adjustment settings, including color-adjustment matrices, grayscale-adjustment matrices, gamma-correction values, color-map tables, and color-threshold values. Remarks The colors in an image can be manipulated during rendering. They can be corrected, darkened, lightened, removed, and so on. To apply such manipulations, initialize a TGPImageAttributes object and pass the address of that TGPImageAttributes object (along with the address of an Image object) to the TGPGraphics.DrawImage method.
