python - Image resize under PhotoImage

Question

I need to resize an image, but I want to avoid PIL, since I cannot make it work under OS X - don't ask me why...

Anyway since I am satisfied with gif/pgm/ppm, the PhotoImage class is ok for me:

photoImg = PhotoImage(file=imgfn)
images.append(photoImg)
text.image_create(INSERT, image=photoImg)

The problem is - how do I resize the image? The following works only with PIL, which is the non-PIL equivalent?

img = Image.open(imgfn)
img = img.resize((w,h), Image.ANTIALIAS)
photoImg = ImageTk.PhotoImage(img)
images.append(photoImg)
text.image_create(INSERT, image=photoImg) 

Thank you!

Answer 1

Because both zoom() and subsample() want integer as parameters, I used both.

I had to resize 320x320 image to 250x250, I ended up with

imgpath = '/path/to/img.png'
img = PhotoImage(file=imgpath)
img = img.zoom(25) #with 250, I ended up running out of memory
img = img.subsample(32) #mechanically, here it is adjusted to 32 instead of 320
panel = Label(root, image = img)
