I'm having problem with converting a PDF file to gif. Please check the following image. The top one is converted gif file and the bottom one is the original PDF file. Can you tell me how can I fix this?
I'm using "convert -density 200 file.pdf file.gif" command.

We use the Ghostscript delegate library or program to render PDF. The problem you posted is mostly due to Ghostscript. The latest GPL release is 8.60. Which version are you using? Perhaps an upgrade will fix the problem.

The boxes are usually a sign that the font could not handle the given character. The '-' and '+' symbols is probably a special Unicode 'minus' and 'plus' rather that the simple ASCII equivalent, and that is not being provided by the font. It may be the font in ghostscript is not as complete as expected.
Not all fonts implement the whole Unicode charcater set, most skip certain sections and parts. the symbols may have been skipped as being unnecessary as the ASCII character is normally used.

I was already using 8.61. I upgraded to 8.63 and it seem to fix the problem.
Thanks for the replies.
