The kitten example is not the url to the actual image data.

The url to an image needs to be a direct link to the image data, no html, no javascript.

good luck!

A wild guess: if you have twice the same outline on top of each other, it is possible a remove overlap can freak out

Wild guess 2: you had some open paths, which are removed by a remove overlap

you need to call randint in side the for loop to get a random number each time, instead you asked for a randint once! at the beginning and you are reusing that number

for i in range(10):
    print(randint(-1000, 1000))

good luck!

Setting a font in a formatted string will only be used for text appended afterwards: txt.font(...) will not alter the font attribute for existing texts in the formatted string.

For each page you will need to create a fresh formatted string.

also read why we dont allow embedding fonts: https://github.com/typemytype/drawbot/issues/23

typemytype created this issue in typemytype/drawbot

open svg fallback fonts #274

typemytype created this issue in typemytype/drawbot

closed embed installed fonts in a svg context #23

there is already a fallbackFont(fontName) see

but no connection with the svg, this would be indeed nice to add, as the fonts are not embedded into the svg.

Embedding of font in svg is not allowed.

yes you can use fontMake or ufo2ft, you just have to install it locally for the python3.6 (this is the embedded python in DrawBot)

If you dont have python3.6 installed, you need to get it from https://www.python.org/downloads/.

and install fontMake and/or ufo2ft with pip3.6 for py3.6

good luck!

ufo2fdk needs some basic font info settings like descender, xHeight, ascender, capHeight, unitsPerEm

# some default example values
font.info.descender=-250
font.info.xHeight=500
font.info.ascender=750
font.info.capHeight=750
font.info.unitsPerEm=1000

Im pushing you to figure it out by yourself first

see the documentation and the source of ufo2fdk

and see documentation of fontMake

font.generate is RoboFont method and is not available inside DrawBot.

However with ufo2fdk (which is embedded into DrawBot) you must be able to generate binaries (you will need to install FDK locally)

or install fontMake and build a compiled font from a ufo.

good luck!!!

so far there is no support for any kind of forms.

A contour object has a contour.clockwise which is a boolean indicating what the direction is. Hope this helps you out.

a segment always represent a line with a single point and a bezier curve with 3 points (2 off curves and one oncurve) this is the behaviour in RoboFab ever since...

A contour object has an attribute contour.open which is a bool indicating a contour should use closePath or endPath for open paths.

oh, there is indeed no progress callback on saveImage(..)

Doing some googling on 'progress' and 'ffmpeg' does not results in a clear solution.

DrawBot has a small wrapper around ffmpeg to generate movies: see https://github.com/typemytype/drawbot/blob/master/drawBot/context/tools/mp4Tools.py

there are plenty of options to have some sort of process bar that gets updated for each frame:

see https://stackoverflow.com/questions/3173320/text-progress-bar-in-the-console#

If this doesn't makes sense I can narrow it down to an simpler example!

good luck!

you can use a clipPath(path) to clip a drawing inside a given bezierPath: see http://www.drawbot.com/content/shapes/drawingPath.html#drawBot.clipPath

you could save the result to disk and open the result in an specified app with:

from drawBot import *

fill(random(), random(), random())
rect(10, 10, 100, 100)

path = "~/Desktop/test.pdf"
saveImage("~/Desktop/test.pdf")

import os
os.system(f"open --background -a Preview {path}")

The tutorial is awesome! Really cool to see the usage of DrawBot from the perspective of an animator!
