Hi all,

Ive been working on a project which uses blender, python and pil but due to
restrictions in the current version of blender ive had to revert to an older
version[2.25] this means older python and older pil. Im now using python 2.0
and PIL 1.1.1.
ive been changing my scripts so that they work with these other versions but am
runnig into problems with PIL, basically in my project blender takes a
screenshot wihch PIL then prints on the default printer, this used to work fine
but with the older PIL all i get is a page full of black where the image should
be. If any of you who have any knowledge of old versions of PIL could help me
that would be great, below is the script:(which i stole from the internet
somewhere)

ive had to change

dib = ImageWin.Dib (bmp)

to

dib = ImageWin.Dib (bmp,(1,1))


Any help would be greatly appreciated

Thanks
