I am trying to georeference a rather large PDF. I was successful in doing so without compression.
However, when trying to make the map lighter, I added some compression. The options are: LWZ, PACKBITS, and DEFLATE. No matter which one I use, the output resolution is very low. The partial solution is checking
Set target resolution, but still it only goes so far (1, -1), the output is pixeled and the labels on the old map I'm trying to georeference cannot be read.
I know this problem could be solved if I transform the pdfs into images and pre-resize them. But I'm looking for a more integrated solution. Is there a way to define the target resolution differently?
