pageCount() returning the current page count -->https://www.drawbot.com/content/canvas/pages.html#drawBot.pageCount
textBoxCharacterBounds (I see its not added to the docs yet..) returning a list of typesetted bounding boxes with characters and a subsetted formattedString
help(textBoxCharacterBounds) # :)
hope this helps with your puzzle!
t = "AVA"
font("Garamond")
fontSize(200)
text(t, (10, 10))
openTypeFeatures(kern=False)
text(t, (10, 200))
newDrawing() completely reset the drawing stack, as @imik mentioned.
Use newDrawing if you want to generate multiple drawings, or when you are in an environment where the drawing stack is kept in memory and a hard reset of the drawing stack is required.
see the docs: https://www.drawbot.com/content/canvas/pages.html#drawBot.newDrawing
an other option is to use path.expandStroke(10) so you can do point inside testing.
In the current release you can set antiAliasing as an option while saving the context to an image. Set it to True.
see https://www.drawbot.com/content/canvas/saveImage.html#drawBot.saveImage
hope this helps
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:

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)
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.
It is always possible!!! maybe the easiest option is open a html view and place a generated gif...
other options are: create a window with a nsview that is looping over all the pages of your generated pdf and draw each one
Or if you wish it works similar like processing: create a "refreshing" loop in a nsview drawRect_ and call a callback each time.
For now this is out of scope of DrawBot, Im sorry...
If you simply wish to set frame rate use frameDuration() on every newly added page. see frameDuration.
hope this helps!!
an other option:
use the vanilla argument continuous for input controls like sliders:
Variable([
dict(name="foo", ui="Slider", args=dict(continuous=False)),
dict(name="bar", ui="Slider")
], globals())
print(foo, bar)
a lot of issue 
what is color?
a vanilla colorWell is not callable, most vanilla controls have .get() to retrieve the data of the control.
import vanilla
import drawBot
from AppKit import NSColor
# create a custom controller calss
class MyController:
def __init__(self):
# use vanilla to create a window
self.w = vanilla.Window((800, 800), minSize=(200, 200))
# add a text box
self.w.textSizeText = vanilla.TextBox((10, 10, -10, 22), "Text Size:")
# add a slider
self.w.textSize = vanilla.Slider((80, 10, -10, 22), value=20, minValue=8, maxValue=50)
# add a button and set the hit callback to `drawIt`
self.w.update = vanilla.Button((150, 40, -150, 22), "Update", callback=self.drawIt)
self.w.colors = vanilla.ColorWell((10, 60, -750, -700),color=NSColor.redColor())
self.w.checkBox = vanilla.CheckBox((60, 80, -10, 20), "use color", value=True)
# add a drawBot preview
self.w.preview = drawBot.ui.drawView.DrawView((0, 120, 0, 0))
self.w.open() # open the window
def drawIt(self, sender):
# the callback when ever the button is hit
# get the font size from the slider
fontSize = self.w.textSize.get()
# start a new drawing
drawBot.newDrawing()
# add a page
drawBot.newPage(100, 100)
# set a font size
drawBot.fontSize(fontSize)
# draw some thext
drawBot.text(f"{fontSize}pt Hello foo bar", (10, 10))
if self.w.checkBox.get():
color = self.w.colors.get()
else:
color = 0
fill(color)
rect(0,50,self.w.textSize.get(), 30)
# get the pdf document
pdf = drawBot.pdfImage()
# set the pdf document in the preview
self.w.preview.setPDFDocument(pdf)
# clean up
drawBot.endDrawing()
# open your controller
MyController()
second thought it could be a nice feature for Variable...
