Values range from 0 to 255.
Explanation
You can easily retrieve color information from the base image
displayed in the ImageKit Control. All you need to do is to click
on the color in the base image that you want to retrieve and the
respective RGB values for that pixel are set in the PalRed, PalGreen and PalBlue properties.
The PalBlue property refers to the blue value of the pixel
at the clicked location in the base image in the ImageKit
Control.
This property is used most often to make transparent GIF or
PNG files. In order to set a color to be transparent in a GIF
or PNG image you must use the File.PalRed, File.PalGreen, and File.PalBlue
properties. Although you can set these properties directly, it
is sometimes difficult to know the exact color to set. One easy way
is to click on the color in the image that you want to be
transparent, then pass the retrieved RGB values from the
PalRed, PalGreen and PalBlue properties
to the File.PalRed, File.PalGreen, and File.PalBlue properties.
Another way to retrieve the RGB values is by using the
ImageKit.PrintDraw's GetPixel method.
