    ImageMagick convert SVG > PNG problem

    I needed ImageMagick 6.6 on an Ubuntu 10.04 machine, so I compiled 6.6.1-10 from source and have this running on the 10.04 machine. However, when I try to convert a SVG file to PNG, I get this error:
    $ /usr/local/bin/convert draw11.svg test.png
    convert: no decode delegate for this image format `/tmp/magick-XXkWoFuc' @ error/constitute.c/ReadImage/566.
    convert: missing an image filename `test.png' @ error/convert.c/ConvertImageCommand/2970.
    When I run convert -list format, I see the following (relevant) entries:

    SVG  SVG       -w+   Scalable Vector Graphics
    Indicating that there is write support, but no read support for SVG. Could this be the problem? Also, I get this information from convert -list configure:

    $ convert -list configure

    So I have no information whatsoever under DELEGATES. But I am not sure which files and how to install those, if this is the problem. Any help is appreciated.

    Re: ImageMagick convert SVG > PNG problem

    Doesn't look like you have the xml and rsvg packages installed. You need those to handle svg conversions.

    Try installing the appropriate packages to handle the additional formats and then reinstall imagemagick.

    first remove imagemagick and current config

    next install packages libxml2 librsvg2-bin
    (required depends for each package need to be installed and each package might have its own depends so make sure they are all installed or try without first and see if it works - you'll see what's needed in the package tree e.g. )

    then reinstall imagemagick

    you should be good to go
