Problems with imagecopyresize

shawjames

Okay, I have been working on this all day and cannot figure it out... I'm trying to save an image that is passed on by a form, then resizing it and saving a smaller thumbnail of it. I can save the original image, but when I try to resize it and save it, it does not work... Below my script, can anyone help?

//START

//$pPhoto passed to this function as a file from upload form.
$path = "images/photo.jpg";
$thm_path = "images/photo_thm.jpg";

//This works and saves the file
if (!@copy($pPhoto, $path))
print "Fail";

//Resize and create thumbnail
$source = imagecreatefromjpeg($pPhoto);
$dest = imagecreate(200, 100);
imagecopyresized($dest, $source,0,0,0,0,100,100,200,200);

//I tried this and it fails...
if (!ImageJPEG($dest, $thm_path, 90))
print "Fail";
//I also tried this and it fails...
if (!@copy($pPhoto, $thm_path))
print "Fail";

//END

Please use the [php] and [/php] tags when posting PHP code.

If you comment out that line (with the imagecopyresize()), does it all work correctly?

this is a stripped down version of my thumbnail creation function. I also put in some error checks to make sure my initial file upload has worked.


function create_thumb($newWidth,$newHeight) 
		{
 	    	// this->photoloc is the full path of the original image
    		// this->path is the image path
    		// this->thumbname is the name of the new thumb.
    		$img=imagecreatefromjpeg($this->photoloc);

    	// get the fullsize image width and height
    	$ow=imagesx($img); 
    	$oh=imagesy($img); 

	$newimg=imagecreatetruecolor($newWidth,$newHeight); 
	imagecopyresampled($newimg,$img,0,0,0,0,$newWidth,$newHeight,$ow,$oh);
		imagejpeg($newimg, $this->path.$this->thumbname, 50); // add 100 for quality..

		return true; 

		}
	}

think that should do the trick

Oops, the second copy should be "if (!@copy($dest, $thm_path))"
If I comment out the imagecopyresized line, it still does now work...

<?php
//START 

//$pPhoto passed to this function as a file from upload form. 
$path = "images/photo.jpg"; 
$thm_path = "images/photo_thm.jpg"; 

//This works and saves the file 
if (!@copy($pPhoto, $path)) 
print "Fail"; 

//Resize and create thumbnail 
$source = imagecreatefromjpeg($pPhoto); 
$dest = imagecreate(200, 100); 
imagecopyresized($dest, $source,0,0,0,0,100,100,200,200); 

//I tried this and it fails... 
if (!ImageJPEG($dest, $thm_path, 90)) 
print "Fail"; 
//I also tried this and it fails... 
if (!@copy($dest, $thm_path)) 
print "Fail"; 

//END
?>
