[quote author="InsiteFX" date="1336750744"]For an image to look correct you need to keep the image aspct ratio!

512x512 256x256 128x128 64x64 32x32 16x16 8x8 4x4 2x2

Code:

height = 183 / 2;
width  = 697 / 2;

If you change just one axis your image will never look correct!

ok so why we split the height and width on 2 ? i need to crop to a specific size i have the x and y coordonates and based on that i need to crop. If you want i can give you the exact site from where i took the ideea http://fbcover.3fusion.in/
