| | I've been experimenting a little with PHP's image functions and I was trying to see if I could make something that looked 3D, so I started with a cube because it's simple. To make an isometric picture of a cube, you need to start with a regular hexagon. However, making a regular hexagon isn't the easiest thing. Is there a function to create a regular polygon, or specify an angle and magnitude for a vector? |

PHP has image editing functions?! >_>; I never even knew that. I mean, I knew it had tons of mail functions and all that good stuff but never image editing functions. The most recent thing that I have learned that have to do with shapes is something that you add in CSS. It's like this: CODE
-moz-border-radius: #px;
I had no idea you could edit pictures with PHP...

with the GD module loaded as a PHP extension, PHP gains image-editing functions.

Yeah, you can do stuff but it's pretty complicated. Here's an example: http://www.tjhsst.edu/~tsmilack/tests/image.phpThe code is: CODE <?php header("Content-type: image/png"); $img = imagecreate(500,500); $topleft = imagecolorallocate($img,255,0,0); $bottomright = imagecolorallocate($img,255,255,0); $topright = imagecolorallocate($img,0,0,255); $bottomleft = imagecolorallocate($img,0,255,0); $middle = imagecolorallocate($img,255,0,255); $border = imagecolorallocate($img,0,0,0); $diamond = imagecolorallocate($img,255,128,0); imagefilledrectangle($img,0,0,250,250,$topleft); imagefilledrectangle($img,250,0,500,250,$topright); imagefilledrectangle($img,0,250,250,500,$bottomleft); imagefilledrectangle($img,250,250,500,500,$bottomright); imagefilledrectangle($img,125,125,375,375,$middle); $points = array(125,250,250,125,375,250,250,375); imagefilledpolygon($img,$points,4,$diamond); imagerectangle($img,0,0,499,499,$border); imagepng($img); imagedestroy($img); ?>
