Hello NG,

    I am using PIL to load and display some pictures (via 
wxPython) in a GUI. I have added the ability for the user to change the 
linear dimensions of the image (in pixels) and the quality of the image 
in order for the image to be saved in another file. I was wondering if 
is there a way to know in advance, based on the pixel dimensions 
specified by the user and by the image quality, which file size (in 
bytes) I will obtain for the new image (approximatively). Is there a 
way to obtain such result without actually saving the image?

for any hint.
