We have an Issue with some SVG's which are delivered by our customer when converting them to png using ImageMagick:

ImageMagick throws the following error even if the Font Arial is properly installed :
** (magick.exe:3868): WARNING **: couldn't load font ""Arial" Bold Not-Rotated 0.94921875", falling back to "Sans Bold Not-Rotated 0.94921875", expect ugly output.
We found out that ImageMagick seems to have Problems with the fontname placed in quotes in the CDATA section:
If we remove the quotes arround the fontname the problem does not occur.

SVG without quotes:

It seems that theese svg's where created with Coral Draw. It would be great if ImageMagick could handle such SVG's properly.

Tested with ImageMagick 7.0.8-12 Q16 x64 2018-09-23 as well as with ImageMagick-7.0.5-10-Q16

I have tested your SVG file using IM 7.0.8-12 Q16 Mac OSX Sierra using both the internal MSVG SVG renderer and using Inkscape (0.92.3_4) called by Imagemagick. Neither give that error message. The MSVG rendered does not work properly and the main area is black. The Inkscape version seems to render correctly.

Code: Select all

magick -background none MSVG:corel.svg corel_msvg.png
Image

Code: Select all

magick -background none corel.svg corel_inkscape.png
Image

I also used RSVG (2.42.2_2) delegate, but IM 7.0.8.12 has a problem so I used IM 6.9.10.12. (I created a special RSVG entry in my delegates.xml file to be able to use RSVG as well as Inkscape)

Code: Select all

magick -background none RSVG:corel.svg corel_rsvg.png
magick: unable to open image 'RSVG:corel.svg': No such file or directory @ error/blob.c/OpenBlob/3489.

Code: Select all

convert -background none RSVG:corel.svg corel_rsvg.png
Image


Photoshop shows a rendering with transparent background similar to the RSVG and Inkscape results, which vary slightly.

Thanks for your investigation.

It seems that the problem does only occur unter Windows (Tested with Windows 10).
With debian stable (ImageMagick 6.9.7-4 Q16 x86_64 20170114) we could not reproduce the Problem.

I saw some changes in the rsvg-lib made in August which mentioned changes with quotes. The rsvg-Lib used in ImageMagick is from Dec 2017.

Unter Windows transforming the svg using inkscape works fine.

Have you tried updating the RSVG delegate if that is what you are using? Or have you tried using Inkscape?

For the test with inkscape I used the command line for Inkscape directly, not the way via ImageMagick.
The cmd for the Inkscape-Test was:
inkscape.exe Test-Orig.svg --export-png=Inkscapetest.png

Does somebody have an idea on how to solve that problem?
