[RESOLVED] GD image problem

[severndigital]

ok I keep trying to debug this and can't get anywhere.

the error i get is

Warning: imagepng(): supplied argument is not a valid Image resource in gdtests/test.php on line 18

the line number will be wrong because i have alot of lines commented out in the code. but the active lines are below.

i am assuming it is because i have a syntax error in my code, but i can't find it anywhere.

<?
$source_file = 'images/theunit.jpg';

// Load a source image
$iSource = imagecreatefromjpeg($source_file);

//resize the overlaid image.
$orig_imgsize = getimagesize($source_file);
	$orig_width 	= $orig_imgsize['0'];
	$orig_height	= $orig_imgsize['1'];
	$img_n			= imagecreatetruecolor (200, 200);  

	$iSourceR 		= imagecopyresampled($img_n, $iSource, 0, 0, 0, 0, 200, 200, $org_width, $org_height);

//output to resized image to file.
imagepng($iSourceR,"images/resized.png");
?>

can anyone shed some light on this. I have verified that the director is chmod 777 I also have verfied that the image I am trying to resize exists at the correct location.

thank you,
chris

imagecopyresampled() will return true or false so $iSourceR will be boolean, not image resource. $img_n is the destination so use it. Try this:

...
imagecopyresampled($img_n, $iSource, 0, 0, 0, 0, 200, 200, $org_width, $org_height);

//output to resized image to file.
imagepng($img_n,"images/resized.png");
