Great, thank you both!

@gferreira Thank you! That is much clearer now. I found that in my example I have a lot of transformations and somewhere it gets weird again, but on its own it works!

and the 'official' docs are on robotools.dev! --> vanilla.robotools.dev the one you are referring to is out dated...

@hzinn not sure how best to improve this more frames and higher resolution might be a start and maybe adding a background.

@frederik This makes sense. Thanks!

Hello @frederik ! Thank you! it works for me May I add those few lines found on this other tutorial about "EaseInOut" function. def easeInOut(factor): assert 0 <= factor <= 1 return (1 - cos(factor * pi)) / 2 It will add a new graph with easeInOut. It is working well with your previous lines. Thank you for your help ! Be safe.

@MauriceMeilleur An arbitrary amount of circles seemingly overlapping: import random number_of_circles = 10 radius = 100 wobble = 400 canvas_size = 1000 circles = [] drawn_circles = [] center = canvas_size / 2 # Create circles for i in range(number_of_circles): x = center - (wobble * 0.5) + random.random() * wobble y = center - (wobble * 0.5) + random.random() * wobble circle = BezierPath() circle.oval(x - radius, y - radius, radius * 2, radius * 2) circles.append(circle) # Check if circles overlap for circle in circles: for i in range(len(drawn_circles)): intersecting_shape = circle.intersection(circles[i]) if len(intersecting_shape.points) > 0: circle = circle.difference(circles[i]) drawn_circles.append(circle) # Draw circles, or what’s left of them newPage(canvas_size, canvas_size) fill(None) stroke(0) for circle in drawn_circles: drawPath(circle)

I don't know why but my wild guess is it has todo with drawing ovals at more extreme w, h ratios, when the points are on the extremes you will need a pushing point in the middle to nice curve back. @gferreira you method only works for circles... the drawBot RoboFont extension has points on the extremes, cause the context is type... see https://github.com/typemytype/drawBotRoboFontExtension/blob/master/DrawBot.roboFontExt/lib/glyphContext.py#L23 see the big difference when the oval is getting thinner... def straightOval(x, y, w, h): c = 0.55 hx = w * c * .5 hy = h * c * .5 path = BezierPath() path.moveTo((x + w * .5, y)) path.curveTo((x + w * .5 + hx, y), (x + w, y + h * .5 - hy), (x + w, y + h * .5)) path.curveTo((x + w, y + h * .5 + hy), (x + w * .5 + hx, y + h), (x + w * .5, y + h)) path.curveTo((x + w * .5 - hx, y + h), (x, y + h * .5 + hy), (x, y + h * .5)) path.curveTo((x, y + h * .5 - hy), (x + w * .5 - hx, y), (x + w * .5, y)) path.closePath() drawPath(path) x, y, w, h = 10, 10, 8.0, 146.0 oval(x, y, w, h) straightOval(x + w + 10, y, w, h)

@michelangelo you can use DrawBot inside RoboFont with the DrawBot extension

@frederik You opened a door to a whole new world for me. This is much simpler than I thought. And at the same time, I think it’s going to take me some time to get my head around all this pen-stuff. Thanks!

this should be resolved in the latest update!!!

Hi, @frederik: why generate a binary and read the the binary back in? see f1.generate("otfcff", "f1.otf") You mean I can use the opened ufo files right away as f1 and f2 to interpolate with, right? Give you new font a unique name based on the interp_factor. The font familyName and styleName makes up the postScriptName which has to be unique to set a font in drawBot (and everywhere else). In your case the font familyName and styleName will be "None" "None". This is not good... All right. I thought that after uninstalling the interpolated font I could generate another one I could use in the new page afterwards. So, in this case, would it make sense to set the same name for familyName while the styleName could be related to inerp_factor as you say?

DrawBot has an abstract stack of "actions" which can be applied on different contexts. One context is your output: an animated gif. And there is always a drawBot context to create the preview pdf data. Using drawBot from the module helps in this case as @gferreira suggested.

@gferreira great!!!! thank you very much.

g is just a reference to the same object. You need to create a copy to get a new object with the same content. import copy a = 1 b = [(a, a), (a + 1, a + 1)] print(id(b)) g = b print(id(g)) g = copy.deepcopy(b) print(id(g))

@frederik Thanks (and thanks for opening this over in the GitHub repo). I'll give it a try later today. Speed isn't a factor in this case because I'm generating static diagrams.

The documentation is adjusted and path.onCurvePoints and path.offCurvePoints and the path contours are immutable now. see https://github.com/typemytype/drawbot/pull/350

Ah yes! Thanks @gferreira, I’ll try that.
