What this function does is figures out the correct proportions of an image, and returns those in an array of 2 keys; [0] being width and [1] being height.
You can use this if you want to resize an image, but not actually save that file. this is the same thing as taking a 1024x768 image, and doing <img src="/img_articles/12082/./images/img.jpg" width="50" height="38">.
Here is a samle file showing the usage.
| <?
require_once 'func_images.php'; $obj_images = new images(); $resize = $obj_images->fly_resize("./test/Picture_1.jpg", "50", "50"); echo<<<EOF <img src="/img_articles/12082/./test/Picture_1.jpg" width="$resize[0]" height="$resize[1]"> EOF; ?> |
Well, thats all for the Image Class. Hopefully I comes in handy for you, I know it does for me :)
