I have several scanned b/w png images with all the same resolution (1200 dpi) but of different size.
Now I would like to extend them all with a white border to a certain number of pixels but the border size would be different for each png. Using "-S" also does not work as this scales each png differently.
How can this be done by img2pdf? Or do you know another alternative?
Thanks!

Okay, so if I understand correctly, you would like to have all your images scaled by the same factor and then place them on equally sized pages? Did you try setting --imgsize 1200dpi --pagesize XxY where you replace X and Y by a value that allows all your images to fit into that page?

oops, sorry, I didn't realize that dpi is also a valid unit. Thanks a lot! It works, great!
