Can I use RSVG while still having Inkscape to convert SVG files?

I recently installed Inkscape on my Mac OSX Sierra with IM 6.9.10.11 Q16 while keeping my RSVG delegate.
Still shows RSVG, but when I convert an SVG file to PNG with -verbose, it properly shows it using Inkscape.
I tried
But that did not work.
Is there some way that I can still use RSVG, so I can compare the results with Inkscape?

IM doesn't recognise "RSVG:" as a prefix. This would be a useful enhancement to IM.
"MSVG:" is a valid prefix, to force the use of MSVG.
Otherwise, when Inkscape is on your path, IM will always use it.

I tried changing the
Code: Select all
<delegate decode="svg:decode" stealth="True" command=""inkscape" " ...
command in the delegates.xml file to use rsvg-convert, but that failed.
Code: Select all
'rsvg-convert' '/tmp/magick-861shrDPgMVA4CJ' --export-png='/tmp/magick-861ZrimwaBF9BnC' --export-dpi='300,300' --export-background='rgb(100%,100%,100%)' --export-background-opacity='1' > '/tmp/magick-861X39YPVeQd2VV' 2>&1
convert: negative or zero image size `test.svg' @ error/image.c/SetImageExtent/2700.
convert: no decode delegate for this image format `test.svg' @ error/svg.c/ReadSVGImage/3374.
convert: no images defined `test.png' @ error/convert.c/ConvertImageCommand/3258.

Those are valid options for Inkscape. According to "rsvg-convert --help", they are not valid options for rsvg-convert (v2.40.20 on my Windows 8.1 laptop).

Thanks. I will have to look into it further. But I would agree that being able to do
would be a nice addition.

I insert this line into delegates.xml:
Code: Select all
<delegate decode="arg" command=""rsvg-convert" -o "%o" "%i""/>
Then I can use "arg:" as a prefix for SVG files that I want delegated to the rsvg-convert program.
But there is a problem: on Windows, IM puts temporary files in %TEMP% which is an environment variable that expands to C:\Users\Alan\AppData\Local\Temp or whatever, and rsvg-convert doesn't like this.
The workaround is to tell IM to use something else, like ".":
Then we can:
Code: Select all
magick -verbose arg:mysvg.svg x.png
... and verbose confirms it works:
Code: Select all
"rsvg-convert" -o ".\magick-7728MN-pOkPjVz_x" ".\magick-7728zgeQzPvqQ1FW"
arg:mysvg.svg=>mysvg.svg PNG 482x579 482x579+0+0 8-bit sRGB 29780B 0.031u 0:0
.016
arg:mysvg.svg=>x.png PNG 482x579 482x579+0+0 8-bit sRGB 29961B 0.250u 0:00.187

Adding this
Code: Select all
<delegate decode="rsvg" command=""rsvg-convert" -o "%o" "%i""/>
seems to work fine for me on my Mac. I don't see any ImageMagick files left in /tmp.
convert -verbose
