Tips & How to Information

ABBYY offers licenses that count pages - DIN A4 pages (210 x 297 mm).

  • If a page is processed that is smaller than A4 then at least one A4 page is counted
  • When a page that is bigger than A4 , for example A3, is processed then the page counter is reduced with more pages:
    • A3 = 2 x A4
    • A2 = 2 x A3 = 4 x A4 - so minimum 4 pages will be counted
  • In reality the situation is more complicated, because the physical paper size is one thing, but the size of the digital image depends on the scan/image resolution.
    So at the end the number of pixels of an image is important.

Page Count and Paper Size

  • For pages larger than A4 the counter of recognized pages increases by the number
    (area of the page)/(area of A4) )
  • To calculate the width and height of a page we use the following formula:
    int imageWidth = image→GetWidth() / max( 1, image→GetResolution() )
    int imageHeight = image→GetHeight() / max( 1, image→GetResolution() ); [image is an Image Object].
    • This object represents a single “image plane” (black-and-white, color or preview) of an image in internal format.
    • imageWidth and imageHeight are values in inches.
    • If you need the size in centimeters you just need to know 1 inch = 2,54 cm.
