Nevermind, I figured it out. Instead of using the ImageInfo->magick, you need to set the ImageInfo->filename to include the magick prefix.

so,

strcpy( imageinfo->filename, filename );

would need to be set to

strcpy( imageinfo->filename, "KSVG:" );
strcat( imageinfo->filename, filename );

Then ...

I have the delegate working if I prefix display or convert with KSVG:. How do I translate that to the C api? I thought it was a matter of setting the ImageInfo->magick before calling ReadImage().

Yes, it is in /etc/ImageMagick/ and it being picked up. Verified that with strace.

No. It gives the same error.

rh6gold:dev/tls>/usr/bin/display KSVG:ansg011.svg
display: no decode delegate for this image format `/tmp/magick-geY7prO8' @ error/constitute.c/ReadImage/566.

Though I renamed the svg delegate to rsvg and that worked.
rh6gold:dev/tls>/usr/bin/display RSVG:ansg011.svg
<displays>

How do you setup a delegate for a KSVG: prefix? I thought it was just as simple as adding a line in the delegates.xml like

<delegate decode="ksvg" command=""/usr/bin/ksvgtopng" "%i" "%o""/>

In the simplest repro, the file fails to display properly, if I use

1) display ansg011.svg
2) rsvg-view ansg011.svg
3) rsvg-convert ansg011.svg > ansg011.png
display ansg011.png

It displays properly, if I use

1) gwenview ansg011.svg
2) ksvgtopng ... ansg011.svg ansg011.png
display ansg011.png ...

Yes, I use the C api. My example for ImageMagick not working is display, broken down to rsvg(-view) failing.

I don't use convert, so how do you make this work through the api?

Sorry, I'm not sure what font that is, but it is part of our product.

Here is what happens when I run rsvg-convert
ftp://ftp.sas.com/outgoing/ImageMagick/rsvg.png

and when I run ksvgtopng
ftp://ftp.sas.com/outgoing/ImageMagick/ksvgto.png

As you can see, the ksvgtopng is picking up the font, rsvg ...

You can find the sample svg here.

Note: this is only a problem with the rsvg product.

The
Z=31.6

should be like
̿X=31.6

Which is a Combining Double Overline + Capital X. You may have issues seeing this, if you Linux box doesn't have the ...

I would like to note, this file views properly with gwenview, firefox, display (if converted using ksvgtopng).

No, it didn't covert the unicode character properly.

All of my conversions are done in the api, not in the tools. the simple observation is

display my.svg

Where there are several fonts being used and various UTF8 characters.

I am using The ImageMagick that comes with Red Hat 6.7. It is picking up the librsvg shared object to convert svg material. The verison of rsvg installed on the rh6 machine, as well as the latest version, fail to convert the text on the page properly. I am able to view this thorugh gwenview and ...
