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!
this should give you the perceived execution time of script:
import time
start = time.time()
# do something
end = time.time()
print(end - start)
@MishaHeesakkers animated gifs can be viewed with a browser. see this example
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!
