How I would convert the image is im.convert("L") I have had success
using this method for a variety of less common formats, and it handles
all the conversion for you.

while using PIL 1.16 recently, I noticed that ImageStat seems to do a

There is a function for this. from the handbook:

Do F (floating point) images support the im.filter method and/or the filters
in ImageFilter? When I tried to filter an F mode image I received
ValueError: image has wrong mode.
The documentation doesn't mention this either way.

Hm.. you seem to be right. One thing you might do is im =

My best suggestion is to convert the font you need to a format that
PIL can understand, either its own bitmap format or to a truetype
font. Font conversion utilities exist, and you would only need to do
the conversion once, and then just use the converted font. It may not
be completely elegant, but

Reading gimp files is tricky. Resizing photos is not hard just

Image module for details on adding logos and bars. The ImageDraw

Something that would be simple would be a wrapper class containing an
image as an attribute. You could reference the wrapper instead of the
image itself, which would solve your problem. I think you could write
a wrapper in 20-30 lines of code, and probably have a very small
performance hit if any.

Your problem is that you resized the image twice. Use either the thumbnail

A quick question, is their a way to get an antialiased line or polygon
in PIL? I draw my shapes just fine, but the edges are jagged. Some
packages I know can antialias to reduce the appearance of
pixelization, is PIL one of those?

As far as I can tell, you should be able to determine whether or not
the image has transparency by looking at the mode. if it is RGBA or LA
it has transparency, otherwise it does not. If you need to know what
parts are transparent, look at the mask, obtained by im.split()

I tried this out as well and got the same error. I agree this seems to
be a bug, but in the short term try to get around
using the Image.load() function to create a pixel access object and
loop through the file.
g = a.load() #a is an image

for j in xrange(height):

also take a look at the ImageStat module, which might save some work,

Regarding rotating images, try Image.ANTIALIAS as the filter, I find
