python - How to force Pillow to resize an image to an arbitrary size? -


i need resize images, different sizes 144x144.

all sizes: 968x565, 25x48, 400x400, etc. don't know input. i'm using pillow library python. don't mind losing aspect ratio.

problem is: when using resize method, images complete random sizes. not always, of them don't respect arbitrary size of 144x144 gave method. here sample.

i tried resizing these images using mac os x yosemite's preview , works flawlessly. need in pillow force 144x144 size , work @ least preview in mac?

i can't post whole code, snippet resizes is:

#!/usr/bin/env python # -*- coding: utf-8 -*-  pil import image  im = image.open('canvas_wheat.jpg') im.resize((144, 144), image.antialias) im.save('144.jpg', optimize=true, quality=20)

the problem getting there resize method returns new image object, not storing anywhere. original image im same has been loaded.

check examples on interactive session:

>>> pil import image >>> img = image.open("image.jpg") >>> img.size (952, 804) >>> img2 = img.resize((144,144), image.antialias) >>> img.size (952, 804) >>> img2.size (144, 144) >>>

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
