Keep getting "IndexError: list index out of range"

[davidwachs]

Hey, AWESOME code, but I have an issue...

when it parses my svgs, I keep getting index out of range... any idea what I can do to fix this?

I get this even with simple SVGs:

<svg xmlns="http://www.w3.org/2000/svg" width="6120" height="7920" version="1.1">

 <path d="M 6.078125 -9.390625 C6.078125 -9.9375 6.265625 -11.046875 6.015625 -11.59375 L 5.96875 -11.59375C5.796875 -11.953125 5.296875 -12.09375 4.859375 -12.421875C4.640625 -12.59375 4.421875 -12.953125 4.140625 -12.953125C3.890625 -12.953125 3.3125 -12.703125 2.765625 -12.28125C1.578125 -11.375 0.109375 -9.75 0.109375 -8.671875C0.109375 -8.28125 0.4375 -7.953125 0.859375 -7.78125C2.484375 -7.0625 4.6875 -9.390625 6.078125 -9.390625ZM8.09375 -5.796875C6.4375 -5.65625 5.96875 -6.734375 6.046875 -8.921875C6.078125 -9.9375 6.265625 -11.625 6.265625 -12.34375L6.015625 -12.34375M8.09375 -5.796875" transform="translate(72, 100.8)"/>

I've been struggling with this... any help you can lend would be amazing... thanks so much in advance.

Does this still happen? update: yes it does:

Traceback (most recent call last):
  File "svg2gcode.py", line 60, in <module>
    generate_gcode()
  File "svg2gcode.py", line 51, in generate_gcode
    for x,y in p:
  File "/home/harvie/Temp/svg3gcode/shapes.py", line 184, in point_generator
    cspsubdiv.subdiv( sp, flatness)
  File "/home/harvie/Temp/svg3gcode/cspsubdiv.py", line 22, in subdiv
    p2 = sp[i][0]  
IndexError: list index out of range

It happens with your SVG, but not with mine SVGs... There's probably something that triggers it.

I've used inkscape to break your svg into subpaths and one of the paths it created was empty:

  <path
     d="M 7.984375,7.15625"
     id="path2"
     inkscape:connector-curvature="0" />

probably svg2gcode should detect this and avoid processing such zero length shape?

I don’t use the code anymore so I can’t say. Thanks for asking though.

How to fix this problem?
