Using a list of RGB data for Canvas widget? [(R1, G1, B1), (R2, G2, B2) etc.]

[Nainto]

Hi, I have searched the arhives and Google, plus I have tried this on
my own, but I cannot find a way to convert a list of RGB values to a
Tkinter PhotoImage or BitmapImage to use with the Tkinter canvas
widget.  I'd rather not have to use PIL or anything but pure Python,
it's included modules, and Tkiner. Reason being, I would like to port
this/the project it is in to other platforms that may not have anything
else. Any help would be greatly appreciated. Thanks!
