Hi,
first of all this function is only "half" working on ImageMagick 6.8.9-9, every other version I tested up to 7.0.3-10 did not work "a bit".

I have some svgs where I draw a "hatch", I'm filling some svg objects with that (a repeated line):

<pattern id="horizontalHatch" patternUnits="userSpaceOnUse" width="100" height="100" ><path d="M -1,8 l 101,0" style="stroke:#000000; stroke-width:1" /></pattern>

Then for my "svg-object":

<g fill="url(#horizontalHatch)" stroke="#FFFFFF" stroke-width="1">
...
paths
...
</g>

And then I want to convert it to bitmap.

So only the mentioned imagemagick version is recognizing the pattern-fill at all, all other imagemagick versions ignore it.

But now it's getting weired, if the starting point of the pattern path "M -1,8 l 101,0" is going to be to "high" ex.(M -1,50 l 101,0), then it is also beeing ignored

While nothing else is changing.

Somewhere I read that I have to compile it by myself with librsvg2-dev, but it didnt solve the problem, or do I need a special version of librsvg2-dev?

Why I'm doing this with imagemagick? Cause you cant get rid of the blur effect inkscape is drawing on the output png via cli.

So anyone got an idea?

Regards

I suggest you link to (or paste here, between quotes) a complete SVG that shows the problem.

I just do a simple convert to png on cli results in the first one beeing "hatched", and the second one is just the outline. No idea where this comes from.

IM has three rendering engines for SVG. They are: MSVG, RSVG and Inkscape. I tried this in all three, and they all worked.

Windows 8.1, IM v6.9.5-3. Inkscape 0.91.

I changed the pattern colour from #000000 to #00ff00.
