[Koha-devel] Printing patron cards results in 100% cpu

[Fridolin SOMERS]

Hi,

I have seen something on the doc of this lib :
https://metacpan.org/pod/PDF::FromHTML#<img>-tags

Add the height and width attributes if you are creating the source HTML, 
it keeps PDF::FromHTML from having to open and read the source image 
file to get the real size. Less file I/O means faster processing.

Maybe it is this problem.

Regards,
