Using The Image Editing Functions Of Php Specifically, lines or regular polygons.

[beeseven 0]

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?

Done a little copying recently?

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:

-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:

The code is:

<?phpheader("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);?>
