Error rendering fonts in svg

When rendering a font in an svg file, whose size is specified as xx pt, ImageMagick sensibly but incorrectly scales the font by the pixel density. According to this file http://www.w3.org/TR/SVG/coords.html#Units in an SVG "1pt" equals "1.25px" and so the font should be the same ...

Re: convert svg to png; font size changes with density

I think it must be an ImageMagick thing. I found a ruby script which uses librsvg and it renders my files as I expect where convert does not.

Re: convert svg to png; font size changes with density

On further reading, I do feel that ImageMagick or librsvg is in error somewhere. This document http://www.w3.org/TR/SVG/coords.html#Units explains that the unit "pt" in SVG should be interpreted as either 1.25px, and therefore the renderer should appropriately scale the font to fit within ...

Re: convert svg to png; font size changes with density

The .svg renders correctly in every browser I have tried, so I think it's OK. But digging some more, I think I have to specify the font-size in pixels not points. Everything works fine then. Thanks for your help.

Re: convert svg to png; font size changes with density

I think I have rsvg; how would I check? convert -density 288 test.svg -resize 25% test.png didn't work. The text is still bunched up. convert -density 72 test.svg test.png gives the text at the height I expected, and with the spacing I expected. I know that points and pixels don't necessarily mix, b...
