Hi,

I am using the bitmapdata class to create an image from a webcam.

I am then trying to save out this image using PHP, but the image colouring is all wrong.

Does anyone know if this is a flash or php problem and how to resolve?

Thanks
PHP code:
 
//If GD library is not installed, say sorry
	if(!function_exists("imagecreate")) die("Sorry, you need GD library to run this example");
	//Capture Post data
	$data = explode(",", $_POST['img']);
	$width = $_POST['width'];
	$height = $_POST['height'];
	//Allocate image
	$image=(function_exists("imagecreatetruecolor"))?imagecreatetruecolor( $width ,$height ):imagecreate( $width ,$height );
	//imagefill($image, 0, 0, 0xFFFFFF);
	//Copy pixels
	$i = 0;
	for($x=0; $x<=$width; $x++){
		for($y=0; $y<=$height; $y++){
			$r = hexdec("0x".substr( $data[$i] , 2 , 2 ));
			$g = hexdec("0x".substr( $data[$i] , 4 , 2 ));
			$b = hexdec("0x".substr( $data[$i++] , 6 , 2 ));
			$color = imagecolorallocate($image, $r, $g, $b);
			imagesetpixel ($image,$x,$y,$color);
		}
	}
	//Output image and clean
	header( "Content-type: image/jpeg" );
	ImageJPEG( $image );
	imagedestroy( $image );

I wouldn't say it's a flash problem, it'll be something with the code. Can I ask what this does or is meant to do exactly? Are you trying to copy an image pixel by pixel to another image?

I just tried running it locally with one image as the input (on the command line) and it threw up an enormous number of notices and error messages.
