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.

frederik

this seems to be fixed:

which pdf are you talking about?

frederik

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)

frederik

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!

frederik

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

good luck!

frederik

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.

frederik

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!!

frederik

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)

frederik

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()

frederik

second thought it could be a nice feature for Variable...

continue here: https://github.com/typemytype/drawbot/issues/383

typemytype created this issue in typemytype/drawbot

closed improve support for "Apply/Build/Update" button in Variable #383

frederik

well, if the Variables is to interactive and your code is to complex, its maybe time to but a different UI around it!!

import vanilla
import drawBot

# create a custom controller calss
class MyController:
    
    def __init__(self):
        # use vanilla to create a window
        self.w = vanilla.Window((400, 400), 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=100)
        # add a button and set the hit callback to `drawIt`
        self.w.update = vanilla.Button((10, 40, -10, 22), "Update", callback=self.drawIt)
        # add a drawBot preview
        self.w.preview = drawBot.ui.drawView.DrawView((0, 70, 0, 0))
        # open the window
        self.w.open()
    
    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))
        # 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()

this could be added to a .drawBot file which is a package to easily distribute complex code: see https://www.drawbot.com/content/drawBotApp/drawBotPackage.html

good luck!!

frederik

mmm, maybe you have to explain what you would like to achieve?

fontParts is a library to read and write and manipulate ufo data.

DrawBot callback font("Helvetica"), fontSize(10) will set attributes needed while type setting some text.

With fontParts you have access to spacing: glyph.width and kerning in the font.kerning object. I would not encourage you to build a type setter

frederik

Calling RFont(showInterface=False) in DrawBot will create a new font object, a new UFO. You can add glyph to the font object by calling `myFont.newGlyph("a"), it will return the glyph object.

If you wish to open an existing ufo you can call: RFont(pathToUfo, showInterface=False) and get glyph data with myExistingFont["a"] (if the ufo contains a glyph).

hope this helps!
good luck!
