Tkinter-PhotoImage question

[Gregor Lingl]

Hi all,

The Tkinter PhotoImage Widget can be set to
"transparen t" with the method blank().

Moreover the color of single pixels or
definite regions can be set with method put.

I'd like to set single pixels (or some rectangular
regions) to "transparen t". Can I use put to
accomplish this, and if so, which first argument
("data") have I to pass to put?

If not, is there another way to do it?

Thanks, Gregor

Hi Gregor,
I know of no way to accomplish this with PhotoImage... I am using PIL which
is *much* more versatile, you have true alpha-blending and masks, and it
also works faster with larger images.
