I have read the following webpages on php.net:
http://www.php.net/manual/en/function.imagefilledpolygon.php
&
http://www.php.net/manual/en/function.imagepolygon.php
Plus, the PHP code is the only code in the file, meaning that there is no HTML or other code in there. I cannot figure out how this code does not draw a blue triangle on a white square. What am I doing wrong?
[php]<?php
$im = imagecreate(100, 100);
//$red = imagecolorallocate($im, 255, 0, 0);
$white = imagecolorallocate($im, 255, 255, 255);
$blue = imagecolorallocate($im, 0, 0, 255);
/*$values = array(
0, 0, //Upper left hand corner
50, 50 //Center point
0, 100 //Bottom left hand corner
);*/
//imagerectangle($im, 0, 0, 100, 100, $white);
//imagepolygon($im, $values, 3, $blue); //Blue Triangle
imagepolygon($im, 0, 0, 50, 50, 0, 100, 3, $blue);
//imagepolygon($im, 0, 0, 50, 50, 0, 100, $blue); //Blue Triangle doesn't work.
//imagerectangle($im, 0, 0, 50, 50, $blue); //Blue Rectangle works!
//imageellipse($im, 50, 50, 75, 75, $blue); //Blue Circle works!
header("Content-type: image/png");
imagepng($im);
imagedestroy($im);
?>[/php]
