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!!

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!

you can calculate the textSize in side a while loop and stop if the text is smaller then the page width:

newPage(1500,1500)

lh = 10

factor = 1
for i in range(17):
    fs = 1 * (i + 1) * factor
    fontSize(fs)
    lineHeight(fs * 0.8)
    # store the text to draw in a variable
    t = f"AaBbCc {round(fs)} pt"
    # start the while, while there is some text in t
    while t:
        # get the text size of that string
        w, h = textSize(t)
        # check if the width is smaller then the page width
        if w < width():
            # break the while loop 
            break
        # the string is still wider then the page width: remove the last character
        t = t[:-1]
    textBox(t, (10, lh, width(), fs))
    lh += fontLineHeight() + 7
    factor += 1

good luck!

Just make the textBox wider?

Thanks @jo!

what version of drawBot do you use?

PIL (pillow) is embedded now as a package inside the app bundle.

cmd + . works in a pre 10.14 OSs...

DrawBot saves your code in a the prefs: with this key: DrawBotCodeBackup. On every startup DrawBot checks this key, if there is something it will open a new window with the stored code.

This could be more visible like saving to disk when it goes bogus...

there is already an issue open for this: https://github.com/typemytype/drawbot/issues/464

which version of DrawBot are you using?

is this happening inside the app or when you use DrawBot as a module?

mm, strange... listNamedInstances must return a dict and listOpenTypeFeatures a list even if the font has no instances or features

could you provide a dummy font? (offlist: frederik@typemytype.com)

and the resulting image

with textSize you can set a limit on the width or on the height.

t = """foo
bar a super long line that will have a line break
more
text"""


x, y, w, h = (10, 10, 300, 300)


fontSize(30)
tw, th = textSize(t, width=w, align="center")

# move the box down by half 
# of the leftover whitespace
textBox(t, (x, y - (h-th)/2, w, h), align="center")

fill(0, 0, 1, .3)
rect(x, y, w, h)
