Imaging libraries in active development?

2012-11-28 Thread Alasdair McAndrew
I'm investigating Python for image processing (having used Matlab, then Octave for some years). And I'm spoiled for choice: PIL and its fork pillow, scipy.ndimage, scikits-image, mahotas, the Python interface to openCV... However, PIL doesn't seem to be in active development. What I want to kn

Thank you for your speedy response! And yes, I was too hasty in firing off a request without the necessary details. And in fact the resize from the PIL Image module does work: f = Image.open('bird-of-paradise-flower-1.jpg') r,c = f.size f2 = f.resize((r//2,c//2)) f2.show() shape(f) # returns(7

Resize RGB image?

2012-11-24 Thread Alasdair McAndrew
I can resize a 2d image "im" with a command something like: r,c = shape(im) im2 = resize(im,(r//2,c//2)) However, resize doesn't seem to work with an RGB image: r,c,n = shape(im) # returns, say 500 600 3 I then need to take each band separately, resize it, and put them all back together with
