function RemoveBlankPages(Tolerance: Double = 0.0; Complete: boolean = true; LeftToRight: boolean = true): Integer;
Locate images in the TImageEnMView of a single color (i.e. blank images) and remove them.
|Parameter ||Description |
|Tolerance ||Determines how tolerant to be in checking color variance (in the range 0.0 to 1.0). For example, if tolerance is 0.1 then 10% of pixels can be of different color and the image would still be considered "blank" |
|Complete ||If true all images are checked. Otherwise the check stops once the first non blank image has been found and removed. |
|LeftToRight ||If true the scan starts at the first image and proceeds to the last (otherwise it proceeds in reverse order) |
Returns the number of removed pages.
