Xtractor Page Coordinates and PDF Units
During search procedures, the SetMarginToIgnore, ExtractImageToFile, GetImage, and GetTextByLocation methods use x, y origin coordinates for location reference.
The location coordinates use PDF units, where 72 PDF units equal 1 inch. This means that the default 8.5 in. x 11 in. PDF page is equal to 612 by 792 PDF units.
You can use the Origin Property to choose the starting reference point for the x,y origin (0,0 point) for PDF pages.
- If you set the Origin Property to 1, the x,y origin is at the top left of the page.
- If you set the Origin Property to 0 (the default setting), the x,y origin is at the bottom left of the page.
