We process a lot of scanned images with our application. As such, we have a feature that allows for the removal of blank pages during this process.

However, it seems we almost always get a False value from IEBitmap.IsBlank even when the page looks all white. I believe this is because there still are some pixels on the image that aren't white.

Is there a way for me to get that value of white pixels or what percentage is white, so that I can still remove some of these "blank" pages using my own threshold numbers and not relying entirely on IsBlank, which isn't working for us now.

Thanks.
