to make stroke width unaffected by scale, you obviously will need to scale it down by same factor as you scaled geometry i.e.:
canvas pathTransform scaleBy: factor.
strokePaint width: myWidth/factor.
Thanks Igor! This works like a charm. I have been intensively working with Athens for a bit more than 3 weeks. I enjoy it very very much. Thanks Igor for all this excellent work! Alexandre

Hi!
Apparently, the width (in pixels) of a stroke in athens seems to vary with the size of the path. Am I right?
For example, I have the following rendering:
<Screen Shot 2014-01-03 at 9.54.29 AM.png>
There is just one code to draw a box, which is:
athensCanvas pathTransform restoreAfter: [ athensCanvas pathTransform translateBy: rectangle center; scaleBy: rectangle extent / 2.
athensCanvas setPaint: color; drawShape: self path.
strokePaint ifNotNil: [ (athensCanvas setStrokePaint: strokePaint) width: 0.1. athensCanvas drawShape: path ] ]
Having a width of 1 makes a very large border. Do I miss something?

Well yes, you are using scaleBy:. That scaling applies to the stroke width of the path as well, Iâd imagine...
Cheers, Henry
