Converting SVG to PNG on QNAP fails

Hi@All,

I´m trying since quite a while to fix a problem I´m having when I want to convert a SVG File to a PNG using Imagemagick.
In the past it worked without any Problem on a Raspberry Pi but last year I switched for some reasons to a QNAP NAS and there I have trouble with ImageMagick.

ImageMagick 6.9.4-8 Q16 was preinstalled but I tested some further Versions (using Entware and QNAP Packages) with a similar Result.

Following the Output with -debug all Option. My Assumption is, that the TMP-Files are not being created, I just don´t know why.
TEMP Directory is set to default in policy.xml (/tmp).

Code: Select all

[/etc/config/ImageMagick-6] # convert -debug all /opt/fhem/www/images/Kindle_Status.svg -type GrayScale -depth 8

Your first line
[/etc/config/ImageMagick-6] # convert -debug all /opt/fhem/www/images/Kindle_Status.svg -type GrayScale -depth 8
Seems to be missing an output. It also looks like you are trying to convert an SVG to PNG and not PNG to SVG. Please clarify.

Perhaps post your exact command line. The line above may have been cut off.

Is RSVG delegate installed with Imagemagick? What do you get from

Code: Select all

convert -version

Is rsvg-convert installed? If not, then that's the problem.

In addition, your command has no output filename.

Thanks, I recognized that with the missing Output File. Indeed I try to convert an SVG to PNG.
The full command Line is:

Code: Select all

convert -debug all /opt/fhem/www/images/Kindle_Status.svg -type GrayScale -depth 8 /opt/fhem/www/images/Kindle_Status.png
Also you seem to be right with rsvg-convert to not being installed right now.
Output of convert -version:

Code: Select all

ersion: ImageMagick 6.9.4-8 Q16 x86_64 2019-09-19 http://www.imagemagick.org
Copyright: Copyright (C) 1999-2016 ImageMagick Studio LLC
License: http://www.imagemagick.org/script/license.php
Features: Cipher DPC
Delegates (built-in): bzlib jng jpeg png tiff
Unfortunately I don´t know how to install rsvg-convert on a QNAP NAS.

EDIT: rsvg seems to be part of librsvg2 which doesn´t seem to exist for QNAP. Any Advice for an alternative or maybe experiences if it is possible to run Imagemagick in a docker container to convert the File?

You have two other options. First, Imagemagick has a built in MSVG/XML renderer. You can see that if you do

convert -list format

look at the line for SVG. At the end, it should list MSVG or XML

The other option is just to install Inkscape. Then Imagemagick will use it if it can be found. You do not have to recompile Imagemagick like you would with RSVG.

Thanks!

MSVG seems to be available:

Code: Select all

MSVG  -w+   ImageMagick's own SVG internal renderer
      SVG  -w+   Scalable Vector Graphics
     SVGZ  -w+   Compressed Scalable Vector Graphics
But how can I use the MSVG renderer instead rsvg?

Regarding Inkscape, I already came across this idea but when I tried it didnt work as well. It looks like Inkscape on QNAP ist not the full package or at least I couldnt find any binaries.

It should run automatically when you do

Code: Select all

convert image.svg image.png
But your delegates do not have xml installed.

Can you install Inkscape on the system, which does not work as a delegate. So IM does not need to be reinstalled.

I installed Inkscape but nothing changed.

I think im going to to a reinstall of the NAS this week. Maybe I screwed something up during testing.
Sometimes it helps to start over from zero :)

I give up. Even after reinstalling no success. I think is jsut not possible without a VM or something similar. I will look for another way somehow.
