BezierPath offset problem.

Hugo Jourdan

Hi,
I would like to translate a BezierPath, without changing it's bounds.

Here is code where you can see my problem.

newPage(2000,2000)

# Grey Rectangle
path0 = BezierPath()
path0.rect(1000,10,200,1990)
with savedState():
    fill(0, 0.1)
    drawPath(path0)

# Green Rectangle
path1 = BezierPath()
path1.text("1", fontSize=200)
with savedState():
    fill(0,1,0)
    rect(*path1.bounds())
drawPath(path1)

# Red Rectangle
path2 = BezierPath()
path2.text("2", fontSize=200, offset=(200,300))
with savedState():
    fill(1,0,0)
    rect(*path2.bounds())
drawPath(path2)

# Yellow Rectangle
path3 = BezierPath()
path3.text("3", fontSize=200)
path3.translate(100,800)
with savedState():
    fill(1,1,0)
    rect(*path3.bounds())
drawPath(path3)

# Magenta Rectangle
translate(900,800)
path4 = BezierPath()
path4.text("4", fontSize=200)
with savedState():
    fill(1,0,1)
    rect(*path4.bounds())
drawPath(path4)

I tested 3 solution:

use offset in path.text
Change BezierPath bounds
use path.translate
Change BezierPath bounds
use translate
Don't change BezierPath bounds

But this is annoying, because I don't want to translate all my canvas just for that.

So what is the solution ?

I found a way.

newPage(2000,2000)

# Red Rectangle
path2 = BezierPath()
path2.text("2", fontSize=200, offset=(200,300))
with savedState():
    fill(1,0,0)
    x = path2.getNSBezierPath().bounds().origin.x
    y = path2.getNSBezierPath().bounds().origin.y
    w = path2.getNSBezierPath().bounds().size.width
    h = path2.getNSBezierPath().bounds().size.height
    rect(x,y,w,h)
drawPath(path2)

I’m not sure if this is even allowed, maybe @frederik will take some reputation points away from me ;-). Also, I’m not sure if the way offset works is correct, or if it’s a bug.

Personally, I would just wrap your fourth solution in a savedState() and accept all the translations of the canvas. I think that would be the DrawBot way.

# Magenta Rectangle
with savedState():
    translate(900,800)
    path4 = BezierPath()
    path4.text("4", fontSize=200)
    with savedState():
        fill(1,0,1)
        rect(*path4.bounds())
    drawPath(path4)

the mistake here is that bounds are not structured as x, y, width, height as required for rect(...)but as minx, miny, maxx, maxy.

minx, miny, maxx, maxy = path.bounds()
rect(minx, miny, maxx-minx, maxy-miny)

@frederik Thanks for this clarification !
