PIL cuts off top of letters

Question

I\'ve spent a lot of time making my first web application using Python, and I\'m using pil for generating images. After reading a lot, I\'ve managed to implement proper text

Answer 1

Not the best solution but I see people have solved this by adding a leading a trailing space to their text.

Answer 2

I hope to be wrong on this one, but the only correct fix relies on patching how _imagingft.c renders the text. PIL depends on FreeType for this task, but PIL seems to be miscalculating the positioning. Also, the height in getsize is overestimated (although that doesn't cause problem). For the moment, I've put a patch to handle these issues at: http://pastebin.com/jP2iLkDN (there seems to be a better way to patch the render code).

Here are some examples of the output I get without the patch and with the patch, respectively:

Here is the code to generate the top figures:

# -*- encoding: utf8 -*-
import sys
import Image, ImageDraw, ImageFont

im = Image.new("RGBA", (1000, 1000), 'white')
draw = ImageDraw.Draw(im)

start_y = 7
text = u'\u00d1\u00d3yŻ\u00d4Ćgp\u010c\u0137'
for i in xrange(28, 46, 2):
    font = ImageFont.truetype('Junicode-Bold.ttf', i)
    width, height = font.getsize(text)
    draw.rectangle((0, start_y, width, height + start_y), outline='blue')
    draw.text((0, start_y), text, font=font, fill='black')
    start_y += height + 7

im.crop((0, 0, width + 1, start_y + 2)).save(sys.argv[1])

The bottom figures were generated according to code present in the linked topic about PIL cutting off parts of the text.
