GetPixel

CATResult CATImage::GetPixel ( CATInt32  x, CATInt32  y, CATColor &  color   ) const GetPixel() retrieves the red, green, blue, and alpha values for a specified pixel. This is for convenience and prototyping - for high-speed image processing you'll need to work more directly with the image buffer. Parameters: x  - x position within the image of the pixel y  - y position within the image of the pixel color  - receives the color of the pixel Returns: CATResult result code. CAT_SUCCESS on success. See also: SetPixel() Definition at line 806 of file CATImage.cpp. References CATCOLOR::a, CATCOLOR::b, CATCOLOR::g, GetPixel(), and CATCOLOR::r.
