[Mapserver-users] RH8 and GD

[Arthur, John]

Here is a test script: Note if the output is changed to gif or jpeg it will work.

<?php 
Header("Content-type: image/png"); 

$image = imagecreate(300, 300);

$red = ImageColorAllocate($image, 204, 0, 0);
$white = ImageColorAllocate($image, 255, 255, 255);
$green = ImageColorAllocate($image, 0, 150, 0);
$black = ImageColorAllocate($image, 0, 0, 0);

ImageFilledRectangle($image, 0, 0, 300, 300, $white);  // white background
ImageRectangle($image, 10, 10, 290, 290, $red);  // red frame

$points = array(
		"0" => "40", 	// x1
		"1" => "50", 	// y1
		"2" => "20", 	// x2
		"3" => "240", 	// y2
		"4" => "60", 	// x3
		"5" => "60", 	// y3
		"6" => "240", 	// x4
		"7" => "20", 	// y4
		"8" => "50", 	// x5
		"9" => "40", 	// y5
		"10" => "10", 	// x6
		"11" => "10", 	// y6
); 

$number = count($points) / 2;

ImageString($image, 5, 15, 250, "There are $number points", $black);


ImageFilledPolygon($image, $points, $number, $red);  


for ($i = 1; $i <= 5; $i++) {  // five fonts
	$k = (($i * 10) + 70);
	ImageString($image, $i, 90, $k, "PHP images", $green); 
}

imagepng($image);  // render image
imagedestroy($image); // free memory

?>

John,

Can you post a simple script that does this so I can try it on my 
config.

Thanks,
