Convert SVG to transparent PNG with antialiasing, using ImageMagick

I want to convert SVG images to PNG files with transparent background and anti-aliased edges (using semi-transparent pixels). Unfortunately I can't get ImageMagick to do the anti-aliasing, the edges always look terrible. Here's what I tried:

convert +antialias -background transparent  in.svg -resize 25x25 out.png

Any ideas or a different command line tool I could use?

Solution

  • Inkscape will do this:

    inkscape \
    --export-png=out.png --export-dpi=200 \
    --export-background-opacity=0 --without-gui in.svg

    Update

    The terminology has changed: all the export params suppress gui, and the output parameter is now simply based on the file type. For example, a type of png will cause a file in /path/to/picture.svg to be exported as /path/to/picture.png (caution: this overwrites output).

    inkscape \
    --export-type=png --export-dpi=200 \
    --export-background-opacity=0 picture.svg

    Note cited wiki has quotes on --export-type=png, which is incorrect.

    Also if don't have Inkscape command line, MacOS can access via bash directly:

    /Applications/Inkscape.app/Contents/MacOS/inkscape
