[IMAGE-SIG] Text in Image?

[Dirk Engelmann]

Hi!

First, I would like to know, if there is a image-format were I can
put a comment or note into the image (not into the grafics).

Second, I've got problems with putting text into an image.

The font conversion to pil was correctly working.


If I have a something like this:


import Image
import ImageDraw

im = Image.open("testimage.ppm")
draw = ImageDraw.ImageDraw(im)
draw.text((20,20), "text")


I get an error message:

    draw.text((20,20), "text")
  File
"/home/dengel/applications/Python/extensions/Imaging/Imaging/Lib/ImageDraw.py",
line 68, in text
    m = self.font.getmask(text)
  File
"/home/dengel/applications/Python/extensions/Imaging/Imaging/Lib/ImageFont.py",
line 84, in getmask
    im.im.paste(self.image.im.crop(tuple(m[6:10])),
SystemError: NULL result without error in call_object


I looked into ImageFont and ImageDraw module, but it wasn't quite clear to
me what went wrong - or if it's my fault.



Thanks for help!


Cheers,

Dirk Engelmann
