A new version is available:

• The launch time is now at lightning speed!

• Added a new keyword argument center for the rotate(), scale(), and skew() functions.

The optional center argument will make the transformation be centered around the given point:

rotate(20, center=(500, 500)) # rotate around (500, 500)
rect(250, 250, 500, 500)

Just for reference: the extra argument does the same as this example but is a lot more convenient:

# define a center point
centerX, centerY = 500, 500
# translate to that center point
translate(centerX, centerY)
# do the transformation
rotate(20)
# translate back 
translate(-centerX, -centerY)
# draw something
rect(250, 250, 500, 500)

Download and Play!!!

that is possible you can use:

from drawBot.context.tools.gifTools import generateGif

generateGif(gifPaths, destinationPath, frameRates)
# gifPaths: a list of paths to gif files
# destinationPath: a path where to save the animated gif
# frameRates: a list with the same length as the gifPaths of ints in 1/100sec

see https://github.com/typemytype/drawbot/blob/master/drawBot/context/tools/gifTools.py#L11

hope this works!

• Adding bezierPath.expandStroke(width, lineCap="round", lineJoin="round", miterLimit=10) (thanks to Bahman Eslami)

• Improved internal OpenType feature tags setting

• Improved complex formattedString type setting

• Improved alignment with text() and FormattedString

• Added a DrawBot frontend for pip/PyPI to make it super easy to install third-party packages: see menu Python -> Install Python Packages...

  

• Fixed text stroke behavior (but is a breaking change): strokeWidth on text no longer scales with the fontSize

• Removed support for .mov export on 10.15 and up (QTKit is no longer supported there)

• Fixed extracting single frames from .gif files

• Improved setup.py, so drawbot-as-a-module can be easily installed with pip using a github URL

• All test now run on Travis CI (and soon also on GitHub Actions)

• Removed Python 2 code

• Many small issues were fixed

• Jumping to python 3.7

  If you use external packages you will need to install them for python 3.7. If you don't have python 3.7 installed you will need to do that first.

• Improved syntax highlighting for python 3

• Fallback fonts are also used in a svg context.

• listNamedInstances() lists all named instances for a variable font.

• BezierPath objects have bezierPath.line(pt1, pt2) and bezierPath.polygon(pt1, pt2, ...) methods.

• Update internal packages!

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}")

I understand the confusion

a much better explanation:

The created arc is defined by a circle inscribed inside the angle specified by three points: the current point, the fromPoint parameter, and the toPoint parameter (in that order). The arc itself lies on the perimeter of the circle, whose radius is specified by the radius parameter. The arc is drawn between the two points of the circle that are tangent to the two legs of the angle.
The arc usually does not contain the points in the fromPoint and toPoint parameters. If the starting point of the arc does not coincide with the current point, a line is drawn between the two points. The starting point of the arc lies on the line defined by the current point and the fromPoint parameter.

I will adjust the drawBot documentation

This is savedState() http://www.drawbot.com/content/canvas/state.html#drawBot.savedState

with savedState():
    # do something

This is more readable and clearer then wrapping code inside a save / restore statement.

For beginners there is not such a big difference:

Strings

All strings are unicode string, so no converting back and forth, but this is actually the best thing!!

print

print('hello world') requires brackets ( and )

divisions

Divisions are always floats so no more rounding, this is also a good thing: 1/3-> 0.333333 instead of 0

You keep the old behaviour with 1//3

If you dive deeper:

dictionaries

dict.keys(), dict.values(), dict.items() are not a lists anymore

Looping (a for loop or a while loop) over a dictionary and changing content of that dictionary is tricky:

for key in list(myDict.keys()):
    myDict[key] = "changed" + myDict[key]

There is of course more

• Python2 or Python3
• What's New
• google it

@thundernixon ssssht py3.6

there are plainly of references in generative art, going from artist like Sol Lewit to graphic designers Juriaan Schrofer and many more.

good luck!!

DrawBot is mac only... that will not change fast as we got now a super high level of typographic support...

However Just started drawBotSkia which has a subset of the DrawBot api but uses skia as backend.

see https://github.com/justvanrossum/drawbot-skia

you can always ignore all warnings with:

import warnings
warnings.simplefilter("ignore")

see https://docs.python.org/3.7/library/warnings.html

which warning?

the mistake here is that bounds are not structured as x, y, width, height as required for rect(...)but as minx, miny, maxx, maxy.

minx, miny, maxx, maxy = path.bounds()
rect(minx, miny, maxx-minx, maxy-miny)

no, you can not.. but DrawBot exists also as a module where you can use your own python.

see https://github.com/typemytype/drawbot#using-drawbot-as-a-python-module

its all the same and very much based on coding flavours

different approach, similar result, here you know the amount of lines exactly.

import random

size(600, 849)

margin = 106
density = [3,2,7,20, 1002] # the amount of lines
rows = len(density)
row_width = width() - 2 * margin
row_height = (height() - 2 * margin) / rows

fill(None)
strokeWidth(1)
stroke(0)

for i, d in enumerate(density):
    y1 = margin + i * row_height
    y2 = y1 + row_height
    x_positions = [random.random() * row_width for _ in range(d)]
    for x in x_positions:
        line((x, y1),(x, y2))

thanks @monomonnik! very well explained!

the while loop at the end makes its maybe a bit unreadable...

you can use random.sample to generate a random list easily:

import random

density = 5
result = random.sample(range(0, 100), density)
print(result)

I guess you made it to difficult...

Variable([
    dict(name="progress", ui="Slider",
            args=dict(
                value=0,
                minValue=0,
                maxValue=1,
                )),
    ], globals())
    
backgroundColors = [
    (0.5, 1, 0.5), 
    (0.5, 1, 1), 
    (0.5, 0, 0), 
    (1, 1, 0), 
    (0.5, 0, 1), 
    (0.5, 0.5, 0.5), 
    (0, 1, 0)
]

# pageW, pageH = (500, 500)
pageW, pageH = width(), height()


advance = pageW * progress

itemCount = len(backgroundColors)
itemWidth = pageW / (itemCount)

moveIndex = int(advance * progress // itemWidth)
backgroundColors = backgroundColors[-moveIndex:] + backgroundColors

for i in range(0, itemCount + 1):
    color = backgroundColors[i]
    fill(*color)    
    rect(itemWidth * (i-moveIndex) - itemWidth + advance * progress, 0, itemWidth, pageH)

fill(None)
stroke(0)
strokeWidth(10)
rect(0, 0, pageW, pageH)

yes, this is the postScript interpretation of expanding a path... this is visually the 'best' solution but from a curve standpoint horrible

Take a look at my Outliner for outlining strokes, there is a pen and multiple options!
