5.5 Getting the size of an image
=====================================

You can read the size of an image in pixels with :

C++ : void TCODImage::getSize(int *w,int *h) const
C   : void TCOD_image_get_size(TCOD_image_t image, int *w,int *h)
Py  : image_get_size(image) # returns w,h

Parameter	Description
image	In the C version, the image handler, obtained with the load function.
w,h	When the function returns, those variables contain the size of the image.

Example :

C++ : TCODImage *pix = new TCODImage(80,50);
      int w,h;
      pix->getSize(&w,&h); // w = 80, h = 50
C   : TCOD_image_t pix = TCOD_image_new(80,50);
      int w,h;
      TCOD_image_get_size(pix,&w,&h); /* w = 80, h = 50 */
Py  : pix = libtcod.image_new(80,50)
      w,h=libtcod.image_get_size(pix)
      # w = 80, h = 50
