| | 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);
?>

Testing Of The Auto Image Resizer
This might be useful for other members also! (0) This is a test to see what image sizes are accepted on the Trap17 forums without the auto-resizer

image. Hmm, interesting. What about 600 x 500 pixels? Okay, good, now how about 650 x 650
pixels? Nope, too much. Let's try 650 x 500 pixels. Ah, the old 640 trick! Let's

Need To Shrink The File Size Of Web Image? - Photoshop Tricks
(3) QUOTE NEED TO SHRINK THE FILE SIZE? USE TRANSPARENCY Want a killer tip for squeezing even
more size out of your GIF Web images? Make something transparent. That's right, if you can pick
an area of your image to make transparent, your file size will drop like a rock. For example, if
you're putting a logo over a white background and you can make the white area around the logo
transparent, your file size will be significantly smaller. The transparent areas are virtually
ignored when determining file size, because, after all, there's nothing there. ....
