image height and width

[Memozio]

Hi,
any suggestions on how to get width and height of an image from an image file? And further, how to get the color value at any point of the image?

That will depend entirely on the type of image and the tools that you are using.
PIL & Tkinter? wxPython? Other? Working with gif, tiff, png, jpeg, etc????

Hey,
I'm using .png image files. I'm working with FrogLogic configured to use Python language.I've already learned that I can use PIL for that, for example:

from PIL import image
im=Image.image( "image.png" )
pring im.size

and it will return tuple of the format (width, height). I'm wondering if I can somehow get those values in separate statements so I can store them for future use in my script!?

[CODE=python]width, height = im.size[/CODE]will "unpack" the tuple. This method is used often, but the tuple size must match the variable assignments or it will throw an exception.
