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 PalGreen
property refers to the green 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, PalGreen, and
File.PalBlue properties.
Another way to retrieve the RGB values is by using the
ImageKit.PrintDraw's GetPixel method.
