convert pdf to png doesn't work complete

[brush51]

Hi folks,

i have a little problem mit imagemagick(version 6.5.5-10) on a Debian Server.
I am root on this server.
I want to convert a PDF to PNG with the following commands:

Code: Select all

convert -scale 100x100 "test.pdf[0]"  output.png

convert test.pdf -density 600x600 -resize 800x560 PNG:'output.png'

The conversion doesn't work correctly. The output.png is not an png. I have checked the header of this file and it is a pdf with the ending of .png.
But i want a original png. Can someone help me?

greets,

Type

• convert -list format

If the PNG format is supported, you get a PNG with a mode of rw-. If its not there, ImageMagick was built without ImageMagick support. To fix download and install the PNG library. Also be sure you have the PNG header files (e.g. png.h). When you configure ImageMagick it tells you whether it validates a particular delegate library. Be sure it does not complain about PNG. Now rebuild ImageMagick and reinstall. Now your PDF to PNG conversion should work as expected.

Hello magick,

yes you're right. I have installed the libpng and after that reinstalled imagemagick.
convert works now!

thanks a lot!

[/code]

I dont really understand this error. convert cant find the font arial, but the error comes from ghostscript? right?

thanks a lot for helping

not sure but perhaps you need to install freetype as well as ghostscript.

i have installed ghostscript and i moved a downloaded fontpackage into the font-folder from ghostscript.
it works now.
