Hi all,
The Tkinter PhotoImage Widget can be set to
"transparent" 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 "transparent". Can I use put to

Why is that I can only get the PhotoImage class to show up when I write
a straight procedural script (no object orientation) but not when I try
to use object-orientation?
These two scripts in theory should produce the same results but they
don't. Is there any reason why?

I have two classes one class inherits dict(), this class just takes in a
path argument much like glob.glob() and loads the image using PhotoImage
into itself, no biggie works fine. The other class inherits Frame and it
implements an add(self, **kw) method passes all of its arguments to a

and then use dict.get(name) as the image argument for the add method the

'image' (can only be constructed from an existing...

Hi,
I'm trying to create a grayscale image class that reads and writes
grayscale Targa format. This works well with smaller images, but
corrupts larger images and creates a "Segmentation fault (core dumped)"
error. I am at a loss as to why this works only part of the time.
I hope it's proper etiquette to post the code below (3 files).
Can someone please show me what's wrong with the following code? I

Hi,
I can only load gif images with Tkinter.PhotoImage and none with BitmapImage.
I tried png, jpg, bmp and xpm and always got this errors :
Traceback (most recent call last):
File "<stdin>", line 1, in ?

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
