hello @imik,

I think conversions between color modes and color profiles are better handled with PIL/Pillow.

here’s a small script to convert a .png image to grayscale (thanks @frederik for the example):

from PIL import Image
img = Image.open('image.png').convert('LA')
img.save('greyscale.png')

you can install and use Pillow from inside DrawBot using the new pip installer:

1. go to the menu Python > Install Python packages…
2. choose Install/Upgrade and type Pillow

hops this helps… good luck!

hi @RicardGarcia,

Anyway, I think I found a way to get this information by counting the amount of points in a segment so that, if there are 2 points it would be a straight line and if there are 3 a curve. Does this make sense?

yes, except there is only 1 point in a straight segment (and 3 in a curve). the first point in a segment is always the last point from the previous one – have a look at this example.

enjoy!

hello @guidoferreyra,

as far as I can tell, the SVG viewBox attribute is not written by DrawBot. but SVG is XML, so you can easily parse and modify it with Python after it has been created:

# draw something, save as svg
size(600, 200)
fill(1, 0, 0)
rect(50, 60, 200, 100)
fill(0, 1, 0)
oval(300, 50, 200, 200)
fill(None)
stroke(0, 0, 1)
strokeWidth(10)
rect(0, 0, width(), height())
svgPath = 'svg-viewport-test.svg'
saveImage(svgPath)

# add viewBox attribute to <svg>
from lxml.etree import parse
xml = parse(svgPath)
svg = xml.getroot()
svg.attrib['viewBox'] = '0 0 180 150'
xml.write(svgPath.replace('.svg', '_viewbox.svg'))

hope this helps… cheers!

hello @RicardGarcia,

a BezierPath is similar to a glyph. here’s how you can access the contours, segments and points:

B = BezierPath()
B.text('a', font='Menlo-Bold', fontSize=1000)

for contour in B.contours:
    print(contour)
    for segment in contour:
        print(segment) # a segment is a list of points
    print()

there’s also points, onCurvePoints and offCurvePoints.

I hope this is what you’re looking for… cheers!

hi @lnp,

the font() command can take a font name OR a path to a font file as argument:

font('myFolder/myFont.ttf')

cheers!

I could get the 'import' and 'reload' to work with a variable as the module-name, but not the 'from ... import *' part. Can I do this?

you can access all names inside a module using dot notation: myModule.aVariable

Also, can the module be in another folder? It's a subfolder of the root where the code is in. So not a complete other location.

yes, the module can be anywhere, and you can tell Python where to find it by adding its parent folder to sys.path:

import sys
sys.path.append('/path/to/folder/')

but unless you are importing code, I think using a data format like json would be more appropriate.

good luck!

@snaders right, I forgot to mention: to update the contents of a module, you need to reload it:

from importlib import reload
import settings
reload(settings)

from settings import *
print(aVariable)
print(anotherVariable)

cheers!

@MauriceMeilleur this can be a start. but creating and using a library involves a bit more:

see How To Write Modules in Python 3 for a step-by-step guide about creating your own modules.

good luck!

hello @snaders,

if your settings.py file lives next to your main script, you can import anything from it:

# settings.py
aVariable = 'hello'
anotherVariable = 42

# main.py
from settings import *
print(aVariable)
print(anotherVariable)

you can also store settings in plain text files or data formats, and read the data into your script. see for example the modules to read/write csv, json, plist, etc.

hope this helps!

ps. see also this character set proof example using the DrawBot extension in RoboFont.
