fonts clipping with PIL

Question

This image was created with PIL. See how the g's and the y's are cut off in this image? How can I prevent this?

The code that created this image is pretty straight forward (abbreviated):

import Image, ImageDraw, ImageFont

im = Image.new("RGBA", (200, 200), 'white')
draw = ImageDraw.Draw(im)

font = ImageFont.truetype("VeraSe.ttf", 12)

draw.text(
           (1, 1),
           " %s: " % "ggjyfFwe__",
           font=font,
           fill='black'
)

draw.text(
           (1, 30),
           " %s" % 15,
           font=font,
           fill='black'
)

im.show()

I tried it with a few different fonts, and it always gets clipped. Surprising;y, googleing "PIL font clipping" returns very few useful hits... I'm using python 2.6.4 and PIL 1.1.6 on Ubuntu 9.10

Answer 1

If you use PIL <=1.1.5, try 1.1.6 version, there was fixed very similarly sounded bug.

Answer 2

My suggestion is, before you create the image object, to get the required size for the text.

This is done using font.getsize("text") (documentation).

In a image generating script I made, I first found the maximum height of one line of text, by calling the equvalient of font.getsize("Åj") (If you only need US-ASCII, you could find the height of "Aj" instead). Then I calculated the required image height and line offsets, including margins and line-spacing.

Answer 3

the font.getsize("Åj") trick works, but it would be better to use strings like "ÅAj" because some fonts don't have the "Å" and so this won't return what you would expect.
