TIEMultiBitmap.RemoveBlankPages
Declaration
function RemoveBlankPages(Tolerance: Double = 0.0; Complete: boolean = true; LeftToRight: boolean = true): Integer;
Description
Locate images in the TIEMultiBitmap 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.
Example
// Remove last blank pages
MBitmap.RemoveBlankPages( 0.0, False, False );
// Remove any pages that are 95% blank
MBitmap.RemoveBlankPages( 0.05 );
