ImageDraw.textsize() returns incorrect textsize for truetype fonts #644
Description
ImageDraw.textsize() does not return correct textsize for truetype fonts.
The return value does not include offset.
So I have to adjust offset using FreeTypeFont.getoffset() to get correct textsize.
from PIL import Image, ImageDraw, ImageFont
image = Image.new('RGB', (512, 256), (255, 255, 255))
drawer = ImageDraw.Draw(image)
font = ImageFont.truetype('/usr/share/fonts/truetype/freefont/FreeSerif.ttf', 32)
# drawing text
STRING = 'Hello, python language!'
drawer.text((10, 10), STRING, fill='black', font=font)
# drawing rectangle surrounding text
size = drawer.textsize(STRING, font=font)
offset = font.getoffset(STRING)
drawer.rectangle((10, 10, 10 + size[0] + offset[0], 10 + size[1] + offset[1]), outline='black')
image.save('example.png', 'PNG')is this correct way?
And, I think ImageDraw.textsize() should return textsize including offset.
