Converting DPI of an EPS-file [solved]
Posted: 2008-10-20T03:04:31-07:00
Hi,
I am trying to change the density (DPI) of an EPS-file with the following command:
But the result is another than expected. The output-file is very small and grainy.
I guess that some things gets lost when converting the image.
The only difference between the input-file and the output-file should be the density - independent of the other properties.
Is it possible to do that?
You can find the output of 'identify -verbose ...' of both files below.
Thank you.
