  That's a nice workaround, thanks! I didn't consider the resolution parameter since I was thinking in terms of the absolute size of the image in pixels only. Maybe I'll put in a feature request, since pixel dimensions feels like a more intuitive way to characterize output.

  Thanks Frederik! I think I've managed to have what I wanted to. Thanks a lot for bringing the whole problem to a more easy approach.

  Thanks @gferreira I tried different ways to calculate the positioning of the first line in the textBox (looking for a magical match between the verticals metrics, lineHeight(), text size…) and I can never find a solution that works systematically from one font to another…

  Hey @frederik Thank you very much for your reply. I did some quick tests with the code you provided but it seems I have not achieved any positive result in saving the pages with the provided color profile data. The results were always GenericRGB for TIFF, JPG and PNG regardless of me also using some other ICC files. dataWithContentsOfFile_ returns an objective-c class NSConcreteData with the data represented as b'…' in it, what I guess is right and what imageColorSyncProfileData needs. Anyway, thanks again for your help.

  @gferreira said in Import python file.: but unless you are importing code Clear. I will look into JSON then. I only load some settings for size and speed and such. Thanks again.

  @frederik But I figured it out! Obviously the fill/stroke properties from the formatted strings won't find their way into the Bezier paths, but I can just add them to the paths directly. (I guess I could just use text, but I want some flexibility in the code for when Kast is a variable font.) Just have to write the code to clean/chop up strings into even lines and size the text to position/size the lines to make fields. A really useful Maurice-bot would tell me to do the work first and then post just to share the results and the code.

  Hello @gferreira, Thanks for the quick reply. I mistakenly thought vanilla just ment that it didn't have any 'addons'. Like vanilla JS... This makes a lot more sense, will look into that! Thanks a lot!

  hello @KevinKarney, welcome to DrawBot! 1. I need the option to build compound objects (with unions, differences, intersections). Is it possible to make (e.g) a torus by differencing 2 circles. Or do I have to create two bezier paths and then do the difference. both methods are possible: you can do it with a single BezierPath by drawing two circles in opposing directions: x, y = 500, 500 r1 = 400 r2 = 300 B = BezierPath() B.oval(x-r1, y-r1, r1*2, r1*2) B.reverse() B.oval(x-r2, y-r2, r2*2, r2*2) fill(0, 1, 0) stroke(1, 0, 0) strokeWidth(10) drawPath(B) or you can draw two separate circles, and get the difference between them: B1 = BezierPath() B1.oval(x-r1, y-r1, r1*2, r1*2) B2 = BezierPath() B2.oval(x-r2, y-r2, r2*2, r2*2) B3 = B1.difference(B2) drawPath(B3) 2. with primitives such as oval or rect, can I incorporate the fill, stroke, strokewidth, etc into the call. In Nodebox 1, I can say (e.g) a = rect(0,0,20,20,stroke=Red,strokewidth=3,fill=Grey, draw=False) This creates an object call a, but does not draw it.... grouping colors and geometry can be done with functions: def a(): stroke(1, 0, 0) strokeWidth(3) fill(0.5) rect(0, 0, 20, 20) a() hope this helps… have fun with the movies, and let us know if you have any other questions.

  hello @burnier & everyone else with the same problem, the latest version of Python is 3.7 DrawBot currently embeds Python 3.6 if you recently installed “Python 3” from python.org, you probably have 3.7. to make modules available in DrawBot, they need to be installed for Python 3.6 (not 3.7). so, the first step is to make sure that you have Python 3.6 installed in your system. you can check that by typing python3.6 in Terminal. if you get -bash: python3.6: command not found, then you need to install Python 3.6 first. you can get it from python.org/downloads. pip is included in Python, so once you have Python 3.6 you should have pip3.6 too. please give it a try, and let us know how it goes… good luck!
