I suspect there is no better solution. But anyway I am surprised, every simple drawing application manages ellipses.
Athens is not an application, it is framework. And why you think that every framework supports drawing ellipses as a basic command/primitive..for instance? I know of at least one, which doesn't - try drawing it with OpenGL. ;)
This is my new experience, so something what the others accepts and live with that, newcomers do not understand :-D Cheers, Jura
Thank you anyway. Juraj

yes, you using stroke for 2nd ellipse, but stroke width is also subject of scaling, that's why it has different width, because of non-uniform scaling (x/y). instead you can first, draw a filled ellipse (blue) and then draw green one over it.

I am not sure how to properly draw ellipse. Right now I draw a path like this:
The path is created that way: -=-=-=-=- computePath path := self athensCanvas createPath: [ :builder | builder absolute; moveTo: 0 @ 0.5; ccwArcTo: 0.5 @ 0.0 angle: 90 degreesToRadians; ccwArcTo: 0.0 @ -0.5 angle: 90 degreesToRadians; ccwArcTo: -0.5 @ 0.0 angle: 90 degreesToRadians; ccwArcTo: 0 @ 0.5 angle: 90 degreesToRadians ] -=-=-=-=-
And draw it like this: -=-=-=-=- drawOn: athensCanvas athensCanvas pathTransform restoreAfter: [ athensCanvas pathTransform scaleBy: rectangle extent asFloatPoint athensCanvas setPaint: color; drawShape: self path. (athensCanvas setStrokePaint: strokePaint) width: (self strokeWidth / self scale) asFloat. athensCanvas drawShape: self path ] -=-=-=-=-
But with a different shapes, the border does not have same width all around the ellipse. See the image:

Is there better way to draw it? Thank you, Jura
