Re: Putting a unicode string on an ImageDraw canvas

Thanks :)

Here is an example that shows how both draw.text and draw.textsize works, as
long as a unicode-supported font is supplied. It also shows how to get the
text size directly from the font object.

import ImageFont, Image, ImageDraw

s = u'\u0623\u0636\u0641'

font = ImageFont.truetype('/host/WINDOWS/Fonts/tahoma.ttf', 12,
encoding='unic')
print font.getsize(s) # no problem, works fine

im = Image.new('RGB', (200,200))
draw = ImageDraw.Draw(im)
print draw.textsize(s, font=font) #fails
