The perforation result seems to be incorrect for images downloaded from the web?

The result given by the Stamp Analyser is probably correct based on the DPI of the image download from the web.The reason you are seeing a result different from the expect value is that the DPI of most web images is normally set to an arbitrary value of 72. This number does not correspond to the DPI at which the original image was scanned.  For accurate results the DPI at which the stamp was scanned must be known.  If the DPI is not known then  the perforation & stamp frame  measurements will be incorrect. The determination of the centering information is not effected, as this is a relative value and does not depend on the DPI.  Click here for for more details on scanning your stamps.

What is the Rakium QR code used for?

The Rakium QR code is used when photographing stamps. Its purpose is to allow the Stamp Analyser to calculate the DPI of the photographed stamps..

When a stamp is photographed by itself, the Stamp Analyser will accurately calculate the  margins widths and the stamp grade. To get an accurate value of the perforations and frame dimensions, the stamp has to be photographed with the QR code.
