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 size irrespective ...

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 ...

I have an .svg file I'd like to render as a .png.

It contains lines like

<g id="ID000008" >
<g transform="translate(68.250,259.228)">
