After an unsuccessful video capture the image returned is all black. Is there a way to tell if an image is all black (with valid width and height)? Can't find where the width and height are assigned. Call to ImageEnMView1.AppendImage(640, 480) creates a black image of H:176 x W:144. Any help would be appreciated

Hi

Please see:

http://www.imageen.com/help/TImageEnProc.GetDominantColor.html

Percentage := ImageEnView.Proc.GetDominantColor(cl);
If Percentage = 100 then
   ShowMessage('the image is blank!');
