Hatch Fill: ValueError: could not convert string to float: '8mm'

[gorenje]

Hi There,

I've got an svg that contains a 'x' coordinate the contains the string '8mm' which can't be parsed.

The SVG works fine in Inkscape (Mac + Linux) and is attached:

.

The stacktrace:

Traceback (most recent call last):
  File "eggbot_hatch.py", line 1784, in <module>
    e.affect()
  File "/Volumes/CaseSensitive/Users/user/Library/Application Support/org.inkscape.Inkscape/config/inkscape/extensions/axidraw_deps/ink_extensions/inkex.py", line 291, in affect
    self.effect()
  File "eggbot_hatch.py", line 1240, in effect
    self.recursivelyTraverseSvg([self.selected[id_]], transform)
  File "eggbot_hatch.py", line 896, in recursivelyTraverseSvg
    x = float(node.get('x'))
ValueError: could not convert string to float: '8mm'

The trace is from mac but the same thing happens on Linux.

Cheers!

A workaround is to convert the qr code to a path using Inkscape Object-to-path feature.

The Hatch Fill utility does not have support for units in elements; yes, using Object to Path is a fine workaround.

The approach that we recommend, if you have the option, is to use the QR code generator in Inkscape. This tool lets you specify an object to use as your "pixel", which can be an object designed with a path fill. This can make things that tile and print much more effectively, without the overlapping pen lines that you get with a hatch fill inside rectangles.

Ok, good to know.

I have nothing against closing this issue, those approaches you mention are fine for me 👍
