Legacy ImageMagick Discussions Archive

Using the Linux command line tool "convert" , I'm able to convert a PDF to TIFF, but the quality is quite poor. Even a cheap converter on my windows platform does a much better job.

Any ideas on how I can increase the quality? Help will be appreciated.

Also, when I use Group4 Compression, it comes out black, what is going on?

At this point im using

convert file.pdf file.tiff and also tried convert file.pdf -compress Group4 file.tiff

use supersamping to get better quality

convert -density 288 image.pdf -resize 25% image.tiff

This supersampling seems to slow down the process quite a bit. I used a package at my last company(adultpdf) and it seemed to convert almost instantly, with higher quality and smaller filesize. I understand ImageMagick is free so I can't really complain but why does this functionality seem so much poorer? Could I be doing something wrong or is this just a case of you get what you pay for?
