Accusoft ImagXpress 13
DocumentBlankPageDetect Method
| AccusoftImagXpress13 ActiveX DLL > ImagXpress Object : DocumentBlankPageDetect Method |
The number of rows of pixels to ignore on the edges (top, left, right and bottom) of the image. If IgnoreBorder is False, this margin applies to the sides of the original image. If IgnoreBorder is True, this margin is applied to the sides of the page, inside the detected border.
Range: 0 - 2,147,483,647
Default: 0
Minimum width or height of a black object considered non-blank. Set it higher to ignore larger objects (causing more pages to be considered blank) or lower to notice smaller objects (causing more pages to be considered non-blank.)
Range: 1 - 2,147,483,647
Default: 10
Maximum spacing between black objects considered connected. Set it higher to cause broken objects to be considered as two parts of a larger object (causing more pages to be considered non-blank) or lower to cause neighboring black objects to be treated separately (causing more pages to be considered blank.)
Range: 0 - 2,147,483,647
Default: 5
Flag to do a quick search for over scan in the border, and moves detection area inside the detected over scanned border. If this property is set to True and the image does not have an actual border, there is a possibility that the method will return a false positive.
Valid Values: True or False
Default: False
