I am looking to create a dotScreen effect via ImageObject and export that as CMYK to be printed. Is there a workflow to achieve this using existing API?

I can see there’s an unmerged PR https://github.com/typemytype/drawbot/pull/554 — wonder if there are any plans on integrating this and if not, what is the blocker here?

Thanks.

Hi @rohernandezz!

Sorry to revive an old topic, but have you had any luck importing the preferences? I can see the .plist file getting modified on settings change, but if I move the file to a different computer the colors are not updated.

Thanks for any pointers.

Hi!

I am looking to for a way to view .py files output using the Drawbot app, i.e. basically the left half of the window with PDF view only (= no code editor) and use something like VS Code on the side to get better DX.

Has anyone found a workflow that would make the Drawbot app automatically refresh the preview on every file edit?

Hello @frederik, thanks so much for your input.

Wow, works just as I described. The problem is I failed to mention I will want to use those rect() as a clipMask() for text, creating a sort of a parallax effect – something like https://dailydrawbot.tumblr.com/post/135907707375/how-now-brown-cow-references-in-this-thread-on.

Thus I need rect() to maintaint its order/index. Here‘s my (faulty) code that I made initially but gave up and thought I will try to fix the endless move across X axis first:

The "optical" effect is more of less how I want it, but the loop breaks as before.

import math

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

pageW, pageH = 500, 500
steps = 5
stepW = int(pageW/steps)

# Canvas with one step more
extendedW = pageW + stepW

textString = "O"
oneside = math.floor(steps/2)
fs = 300
pushX = progress * pageW

newPage(pageW, pageH)

text(str(pushX), (5, 5))

# Draw one extra step
for i, stepStartX in enumerate(range(0, extendedW, stepW)):
    elapsed = (stepStartX+pushX)//(pageW+stepW)

    if elapsed:    
        stepStartX -= (elapsed * pageW) + stepW
        
    x1 = stepStartX + pushX
    x2 = x1 + stepW
    
    mask = BezierPath()
    mask.moveTo((x1, 0))
    mask.lineTo((x2, 0))
    mask.lineTo((x2, pageH))
    mask.lineTo((x1, pageH))
    mask.closePath()
    
    stroke(None)
    fill(0)
    fontSize(fs)
    textW, textH = textSize(textString)
    stepCenter = x1+(stepW-textW)/2
    
    offset = (x1-(oneside*stepW))*-0.5
    
    # Draw mask
    with savedState():
        fill(None)
        stroke(random())
        drawPath(mask)
    
    with savedState():
        fontSize(8)
        text(f'{i}\nStepStartX: {stepStartX}\nx1: {x1}\nelapsed: {elapsed}', (x1, pageH-10))
    
    with savedState():
        clipPath(mask)
        translate(offset, 0)
        textBox(textString, (stepCenter, (pageH-textH)/2, textW, textH))

Any chance you could tell me what I am doing wrong please?

Thanks for your time :—)

Hi!

I am struggling to think of a way to endlessly move a rect() along X axis and "rewind" back to 0 once it moves past page bounds – essentially creating a smooth movement.

Here‘s my code: it kind of works, but it starts to break as soon the cycle runs repeatedly.

I know there must be a mistake sowewhere and my terrible math skills only got me so far:

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

# Use page dimensions as frame for debugging
pageW, pageH = (500, 500)

# Arbitrary backgrounds to tell them apart
backgrounds = [(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)]

newPage(900, 900)

itemCount = 6
itemW = 100
itemH = pageH

translate(200, 200)
offsetX = (progress * pageW) * 4 # Speed up 4x

for item in range(itemCount):
    # Position on init
    startingX = item * itemW
    
    # Move in time
    currentX = startingX + offsetX
    
    # How many times whole cycle elapsed
    fullProgressCount = offsetX // pageW
    
    # How many times this item elapsed
    elapsedCount = (currentX) // pageW
    
    # Rewind to beginning
    rewind = (elapsedCount * pageW) + itemW if elapsedCount else 0
    
    # Real X position
    realX = currentX - rewind

    # Fill and draw
    fill(*backgrounds[item])
    rect(realX, 0, itemW, itemH)
    
    # Debug item
    fill(0)
    text(f'{str(item)}\nReal: {round(realX)}\ncX: {round(currentX)}\nEl: {elapsedCount}\n{rewind}', (currentX - rewind, 560))

# Debug status
fill(0)
text(f'{str(progress)}\n{offsetX}\n{fullProgressCount}', (-100, -100))

# Draw debugging page frame
with savedState():
    fill(None)
    stroke(0)
    rect(0, 0, pageW, pageH)

Thanks so much for any pointers.

@frederik Works beautifully, thank you!

Yes, that would be a workaround. Ideally I‘d like to show all fully visible glyphs and hide all remaining that don‘t fit within canvas bounds, like this:

I was just wondering if there‘s something like hyphenation() that switches from words to glyphs if you know what I mean.

Hello,

Started playing around in Drawbot and loving it so far. I am wondering – is there a way to clip off text inside a textBox on a glyph-by-glyph basis?

I understand dictionary-based hyphenation takes priority, so that‘s what happens:

What I am after is more like:
AaBbCc 2
AaBbCc 22
AaBbCc 225
AaBbCc 225p
AaBbCc 225pt

And not:
AaBbCc
AaBbCc
AaBbCc 225
AaBbCc 225pt

My code so far:

newPage(1500,1500)

lh = 10

factor = 1
for i in range(17):
    fs = 1 * (i + 1) * factor
    fontSize(fs)
    lineHeight(fs * 0.8)
    textBox(f"AaBbCc {round(fs)} pt", (10, lh, width(), fs))
    lh += fontLineHeight() + 7
    factor += 1

Hopefully makes sense :—) Thanks for any pointers!
