Raster jpg quality

daneren2005
What compression level is used for the jpg rasters from Prince? And is there a way to control that anywhere? I am using `raster-format=jpg` from the command line. I have it set to 300 DPI, but I have a customer complaining that the image is too soft so I am wondering if it is a compression issue or not.

You could use PNG output, if lossy compression is not appropriate.

I don't think I need to go to the extreme of using PNG. I was just wondering what jpg compression it is using and if there is a way to control that. If you are already using decently high compression this customer might just be not liking something that has nothing to with the compression anyways.

The quality parameter given to libjpeg is 92. There is no option to control it at the moment.
