[SOLVED] gd creates black image

[evanct]

I have an image resize function that scales an image to a width of 800px if it's too big. It's been outputting a solid black image of the correct dimensions. What's strange is that my thumbnail function is virtually identical to it, yet it works perfectly. I've tried several images of several different filetypes and it's always the same result.

 

<?php
function imgCreate($ext,$image) {
	switch ($ext) {
		case 'jpg':
		case 'jpeg':
		$img=imagecreatefromjpeg($image);
		break;
		case 'png':
		$img=imagecreatefrompng($image);
		break;
		case 'gif':
		$img=imagecreatefromgif($image);
		break;
	}
	return $img;
}

function saveImg($ext,$img,$path) {
	switch ($ext) {
		case 'jpg':
		case 'jpeg':
		imagejpeg($img,$path,JPEG_QUALITY);
		break;
		case 'png':
		imagepng($img,$path);
		break;
		case 'gif':
		imagegif($img,$path);
		break;
	}
}

function resizeImage($image,$filename,$path,$ext,$ratio) {
	$tmp=$this->imgCreate($ext,$image);
	$newwidth=MAX_IMAGE_WIDTH;
	$newheight=$newwidth*$ratio;
	$img=imagecreatetruecolor($newwidth,$newheight);
	imagecopyresampled($img,$tmp,0,0,0,0,$newwidth,$newheight,$width,$height);
	$this->saveImg($ext,$img,$path.'/'.$filename);
}

function makeThumbnail($image,$filename,$path,$ext,$tn_width,$tn_height) {
	$tmp=$this->imgCreate($ext,$image);

	// some size and coords calculations here, not relevant //

	$img=imagecreatetruecolor(TN_SIZE,TN_SIZE);
	imagecopyresampled($img,$tmp,0,0,$x,$y,TN_SIZE,TN_SIZE,$tn_width,$tn_height);
	$this->saveImg($ext,$img,$path.'/'.$filename);
}
}

?>

 

any ideas?

Oh, duh. I didn't pass $width and $height to resizeImage. careless...
