extract.py expects "translate" elements for all svg objects

[Peter Fillmore]

Inkscape (v0.91) appears to not add "translate" tags to some elements during rendering.
This causes the "util/extract.py" processing to fail when extracting due to the process tag returning "None" for the "translate" tag.
Failing code is (util/extract.py):

50         for shape in shapes:
51             transform_data = utils.parseTransform(shape.get('transform'))

87             for refdef_text in refdef_texts:
88                 # Get refdef group location
89                 transform_data = utils.parseTransform(refdef_text.get('transform'))

So just need to add a check for a "None" value and insert a (0,0) transform to fix.
Or alternatively eliminate the extraction of the "transform" tag when it is not present in the svg.

Yes, I've run into that, and I thought that I fixed it at parseTransform(). I'll take a look.

In branch 'release4' it's fixed like this in utils.parseTransform():

if transform == None:
    data['type'] = 'translate'
    data['location'] = Point()

As a side note, if you're starting out with PCBmodE, I'd go with branch 'release4'. It's complete except that I want to do more work with it before officially merging it with master.

Great - looks good. will clone that branch and start kicking the tyres (will write a blog post on laying out the board i'm making since i found it confusing to start - but once I got the process down it clicks together well).

Very pleased to hear that you persist! r4 now supports any number of layers and moving objects is more intuitive. Also, placing additional shapes is done just like components. Take a look at 'buggy' or 'release4-example' for hints. Documentation is lacking ;)

Feel free to get in touch if you run into trouble and I look forward to see what you've created!
