strukturart/passport

At times it is practically fast to access digital train / airplane qrcode tickets to showcase at a check-in. I wrote an app for that. All image files in a defined order (/passport/) are listed and displayed via enter.

passport's Issues

bottom and right border to big

Hello. Thanks a lot for this
I think there is a math error in the qrcode picture generators.
Specifically the part that generate the white border around it.

I've noticed that while the top and left border look to always be the same size, the bottom and right border grow based on the size of the qrcode.

This issue have become apparent when scanning European covid certificates, which are really big.
Almost 1/5 of the screen is white.

I obviously can't send you this one, but here is an example of a small increase.

It doesn't look to be linear to the total size.

even when '/passport' dir is created on the SD card, application does not work as expected

thanks for the app like that - I was looking for something that could help me reduce printing out pages with qr codes!

I am sure I am doing something ; when I start the app, it says: the folder '/passport' does not exist, please create the dir or the dir is empty.

I made '/passport' dir on the SD Card; I even put sth there - created 'images' directory...
