Hello all:
I am looking the sample code posted on PIL website
http://www.pythonware.com/library/pil/handbook/imagedraw.htm
################################################
<<Draw a Grey Cross Over an Image>>
import Image, ImageDraw
im = Image.open("lena.pgm")
draw = ImageDraw.Draw(im)
draw.line((0, 0) + im.size, fill=128)
draw.line((0, im.size[1], im.size[0], 0), fill=128)
del draw # ===>>>> Why we should delete this object draw?
# write to stdout
im.save(sys.stdout, "PNG")
#################################################
Is there any general rule that we must delete the object after using
it?
Thank you
-Daniel
