Frequently asked questions

The PNG output does not work! My images are empty or look weird.

PcbDraw uses ImageMagick to convert generated SVG files into PNG files. ImageMagick does not have a single way of converting SVG into PNG but instead it uses a method based on what tools are available on your system. That means:

  • if you have Inkscape installed, it will use Inkscape. This is the ultimate option as Inkscape can interpret an arbitrary SVG.
  • otherwise, it will use lib-rsvg or internal converter. lib-rsvg work fine with PcbDraw.
  • However, if none above is available, the internal converter is used. This converter is based on MVG and it breaks terribly on complicated SVG files (practically all SVGs generated by PcbDraw).

If you are unsure which methods are available on your system, try invoking ImageMagick directly to see what's happening:

convert -verbose board.svg -o board.png

Based on the output you can see which converters are used. I recommend to install Inkscape.

Also, as of 2021 and the introduction of Inkscape 1.0, there might be a problem with older versions with ImageMagic - see ImageMagick#3564. The solution is to upgrade ImageMagic (the precise versions are referred in the comments above).
