Legacy ImageMagick Discussions Archive

I am using Version: ImageMagick 6.8.9-9 Q16 x86_64 2018-09-28 under Xubuntu 16.04.

I have been using ImageMagick for a few years and never had a problem.

However, recently the -density parameter does not seem to have any effect whatsoever.

I typically use convert like this:
Now, I always get very small PNGs, and regardless what values I enter for density, I always get the same (small) size PNGs. This seems to be the case regardless which PDF I use for input. I tried many, generated from different sources. By "small" I mean the x/y extenstion of the PNG in pixels, not the file size.

This is my problem. There was another problem, which I solved, which I mention here only in case it might be related: I could not use convert anymore because I was getting the "not authorized" error. I solved this by following the instructions here:

This problem has been solved. But it my problem with density not working is still there. Please help.

What is your version of Ghostscript? Perhaps that needs upgrading or downgrading. Please post an example of a PDF that fails for you.

You should be able to get the GS version from:
at a terminal window

Try specifying the units also

Sorry, I want to retract my question, I got it working now in the meanwhile - reason was wrong position of the density parameter. Sorry for the noise.

For PDF files, you need to put the density before reading the PDF file.
