Display, GUI Windows
This window is designed to display an image histogram. The Histogram GUI window also contains menus. From the View menu you can choose "R" to show the red channel population of the pixels; or "I", which shows the arithmetic mean of all channel values for the pixels. For 1, 4, or 8-bit images, you may only select "I".
The GUI Histogram window menus also allow you to save your histogram to a file or to the Clipboard.
By default, the GUI Histogram window will be created with the style WS_OVERLAPPEDWINDOW.
