Ok, that did the internal padding. I meant the blank white areas that are outside that. There are to blank white columns on all the pages, the far right and the far left. I was wondering if that area could be made to go full screen from left to right etc.
Guess no one knows how to increase the cropping resolution? You can see a quality loss for sure. In the past on other scripts I have been able to edit a variable that allowed you to set the quality of the image crop.
