SVG conversion bug

Post by ozby »

Hello,
I have been using imagemagick for a while, since i have upgraded to 6.9.6, my charts which uses opacity (which are created as svg and then converted to png via imagemagick) are not appearing in a right way (it also doesnt work 7.0.5). After spending sometime, i realized it caused when the fill is set before opacity in the svgs. The other converter tools seems to produce same png out of both svgs below.

converting the svg below to png via imagemagick is not returning expected png.
style="fill: #999999; opacity: 0.1;" (doesn't take opacity into consideration)

Code: Select all

convert -list format?

Add -verbose to your command it should tell you which renderer was used.


Please, always provide your IM version and platform when asking questions, since syntax may differ. Also provide your exact command line and if possible your images.

XML indicates you are using the least accurate IM internal MSVG. I would suggest you install Inkscape or RSVG, which are better SVG renderers. But I am not an SVG expert, so I have limites experience and one of the other people on the forum may be able to help further.

What was your exact command line? Can you provide an SVG file and a proper rendering to png and a png that is incorrect and explain what is wrong? You can upload to some free hosting service such as dropbox.com and put the URLs here.
