Paid: Fix issue converting PDF to JPG

[alex123456]

I have a PDF file that has a logo in it. The logo looks normal when viewed in a PDF viewer. Here is a portion of the logo: .

I need to convert the PDF to a png (or jpg) file. I do this using the following command:
/usr/bin/convert -colorspace sRGB -antialias -alpha off -opaque "#e3e3e3" -density 150 -background white -verbose inputPDF.pdf output.png

The output file has a set of weird lines in the logo portion. See the output here:
.

This is running on CentOS7.
ImageMagick verison 6.7.8.9 displays this issue.
I upgrade to ImageMagick 7.0.8 and this issue persists

I'll pay to get this issue resolved (email money transfer). Please email me at mootsalex@gmail.com with the subject:

I can send you the original PDF file so that you can test and figure this out.

Thanks
Alex.

Post the PDF file here so we can test it. I suspect it is the version of Ghostscript you are using. Find the version and post here or upgrade to 9.23, 9.24, or 9.25. I have heard of issues with 9.26 and 9.27.

Your syntax is not correct. -antialias will have no effect. -opaque only works if you set a -fill prior to it. Some of your settings and operators need to be after reading the PDF. So try

Code: Select all

convert -colorspace sRGB -density 150 -verbose inputPDF.pdf -background white -alpha background -alpha off output.png

If you want the background to be white where it might have been transparent. If you want the background to be "#e3e3e3", then use that in place of white in my -background command.

I tried running the convert using your suggested settings but I get the same result.

Any other suggestions?
Thanks!

Just for reference, here is the output of the convert command. I don't see anything out of the ordinary. This is a multi-page PDF file.

But what version of Ghostscript? See Fred's advice above.

Thanks for your help. Upgrading to the latest version of ghostscript resolves this problem. On my Centos7 machine this means upgrading to 9.25.
