Is it possible to use this with standard US Letter sized paper? #14

I want to anonymise a document for printing. However, I noticed the testpage.pdf is using the A4/ISO 216 paper size. If I try to print it, it will be printed at a reduced size because it is a different aspect ratio. Is it possible to use this program with standard US Letter sized paper?

Hi Peter,

good news. Not only the calibration page but also the anonymised pages shall also be put into A4 format automatically by the program. Therefore, the anonymisation mask will always fit. No matter what transformation your printer adds. Also you can change the format in privacy.py. Make sure that you create a fresh calibration page (deda_anonmask_create -w) and always use the same format for anonymising as for the calibration page. Although in our lab the anonymisation has worked, please verify the correct position of the mask on the paper using a microscope or do not rely on the anonymisation 100% otherwise.

Best wishes,

Timo
