Hiho,

what do you mean by "options"?

IMHO the simplest way is something like this:

  from PIL import ImageDraw, ImageFont
# input: img, fontPath, text1
font1 = ImageFont.load(fontPath)
draw1 = ImageDraw.Draw(img)
tSizeX, tSizeY = draw1.textsize(text, font=font1)
# calculate x and y...
draw.text((x, y), text1, font=font1, fill='#000000')
... save img

I have used this with PIL 1.1.4 only.
To my experience text looks nicer on RGB images
(jpeg), so I convert palette images to RGB before
placing objects.

If you want more complex effects like shadow text
or transparent text, take a look at the filters page
and source code of PyAlbum http://pyalbum.sourceforge.net/Filters.html
