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!!

not really a bug: when applying a blur the images gets bigger, check with im.size() before and after the blur is applied.

im.offset() is providing you the correct x, y difference.

this seems to be fixed:
https://www.drawbot.com/content/image/drawingImages.html#drawBot.image

which pdf are you talking about?

try to do saveImage outside the loop with the option multiPage set to True.

saveImage(f"~/Desktop/test/issueContextLeak/RotatingImage.png", multipage=True)    

Somehow your image object got lost in between saveImage actions...

see saveImage options: https://www.drawbot.com/content/canvas/saveImage.html#drawBot.saveImage

Trying to connect every step in a simplified script script.
This runs fine... what is your macOS version?

w = h = 300
r = w / 2

def drawRotatedImage(img, angle, pos):
    x, y = pos
    fill(None)
    stroke(0)
    oval(x - r, y - r, r * 2, r * 2)
    clipPath()
    rotate(angle, center = (x, y))
    image(img, (0, 0))


img = ImageObject()
with img:
    size(w, h)
    fontSize(100)
    text("Heee", (10, 10))

for a in range(0, 360, 30):
    newPage(w, h)
    drawRotatedImage(img, a, (w/2, h/2))

In some cases it's a lot easier to have an object of path to work with, instead of the combo: newPath(), moveTo(..), lineTo(..), curveTo(..), closePath()

stroke(0)
fill(None)
# create a new path object
path = BezierPath()
# add a move to to the path object
path.moveTo((200, 200))
# add a line to to the path object
path.lineTo((200, 100))

# this creates a new path and set it as current path in the stack
newPath()
# add a move to to the current path
moveTo((100, 100))
# add a line to to the current path 
lineTo((100, 200))
# draw the current path
drawPath()

# draw the path, instead of the current one
drawPath(path)

you can slice a formattedString and keep the formatting:

txt = FormattedString()
txt += "hello World"
sub = txt[0:5]
print(sub)

good luck! it will be slow to apply remove overlap to a lot of text

# create a fromatted string
t = FormattedString()
# set a font
t.font("Skia")
# set a font size
t.fontSize(100)
# set colors
t.fill(None)
t.stroke(0)
# print out all variation settings for the current font
print(t.listFontVariations())
# set some variation settings
t.fontVariations(wght=2.34)
# add text
t += "Hello"
# draw the fromatted string into a text box
textBox(t, (10, 10, 300, 250))

# create a bezierPath
path = BezierPath()
# draw the formatted string into the bezier path
# this will now be a path instead of text and a font
path.textBox(t, (10, 10, 300, 250))
# apply remove overlap
path.removeOverlap()
# set color 
stroke(0)
fill(None)
# move the page a bit
translate(300, 0)
# draw the path 
drawPath(path)

Added in DrawBot 3.126
thanks!

DrawBot 3.126 has a continuous flag in Variable that adds a Update button

good luck!

You can convert it to a bezier path and apply remove overlap, but I guess its much easier to draw it twice: once with a stroke and the second time with only a fill with the same color as the background.
