 * This class to resize an image from bigger to smaller size.
 * Supporting PNG, JPG, and GIF image format.
 *
 * if you chose $proportional=true, it means that width or height image is proportional, example:
 * $r = new Resize("test.jpg", 0, 500, true); height image will be 500 pixel and width will be proportional
 * $r = new Resize("test.jpg", 500, 0, true); width image will be 500 pixel and height will be proportional
 *
 * if you chose $proportional=false, it means the width and height image will be customizable, example:
 * $r = new Resize("test.jpg", 500, 500, true); it forces the image size will be 500 pixel width and 500 pixel height

 * Custom pie chart is a class to generate your own pie chart. Easy to use and very simple.
 * You don't need to configure very much. Just set a canvas area, set a value and description for an each pie slice,
 * of course you should add other slices as you like. This pie chart will calculate and generate automatically for you.
 * If need it you can also change the font style, color background and font color.
 * This pie chart could be bind with your data for present a static data such as vooting, data visitor, and other purpose.
