Parameters
- row
- The zero-based row number of the pixel.
- column
- The zero-based column number of the pixel.
Return Value
This method returns a RasterColor value which may represent an index into a image palette, a grayscale value (Medical Imaging only), or red, green, and blue color values.The standard Windows values for RasterColor represent either red, green, and blue color values, or an index into the image palette. A RasterColor value with the RGB value of 0x00BBGGRR represents the blue, green, and red color values for the specified pixel, where 0xBB is the blue value, 0xGG is the green value and 0xRR is the red value. If 0x01000000 is set in the RGB value of RasterColor (0x010000ZZ), the lower 8 bits (0xZZ) represent an index into the image palette which holds the color value.
You can use the SetPixelColor method to assign the returned value to another pixel.
This method uses image coordinates to specify the pixel. Therefore, you must account for the view perspective of the image.
If you specify a pixel that is outside the image or outside the region (if the image has one), this method throws an exception.
This method does not support signed images.
