issue with the image sizes

I used this package to create multiple datasets for this issue. All the created datasets can be found here /data/users/cabdelwahab/pylaia_data_French_XIX-XXe_century/datasets on straton and the configs used to create them here /data/users/cabdelwahab/pylaia_data_French_XIX-XXe_century/data-generator/examples. There are a lot of images that don't have the right size ie:

even though the config I used is correct (double checked by @starride) so maybe there's a bug with the code
