[Image-SIG] antialiasing in pil -2

[Kees van Drongelen / VisualSpace]

Thanks Kevin,

It works for filled objects. With outlined objects the line of 1 
pixel is too thin. Do you know how-to manipulate the outline 
thickness?

anyway thanks for your comment.

Kees van Drongelen.

#

dxy=100
antialiasing=1
scale=4

if antialiasing:
	im=im.resize((dxy[0]*scale, dxy[1]*scale), Image.NEAREST)
	im=im.resize((dxy), Image.BICUBIC)
