Question

If I have an image 2048 x 2048 and I would like an image 1488×1488 450 pixels down from top and 280 pixels from left

is this the right code x.png is the 2048 x 2048 picture:

<?php

$imagesrc_location = 'x.png';

// Get new sizes
list($srcwidth, $srcheight) = getimagesize($imagesrc_location);

$imagedst = imagecreatetruecolor(1488, 1488);
$imagesrc = imagecreatefrompng($imagesrc_location);

if (imagecopyresampled($imagedst,$imagesrc,0,0,280,450,1488,1488,2048,2048)) { 
    // Output image
    header('Content-type: image/png');
    imagepng($imagedst);
} else {
    echo "Could not resize file";

}

Here is a picture showing what I want, the grey part is the cropped picture.

EDIT: I think the problem is, your source size will make the imagecopyresampled scale it down. This may work for a crop:

imagecopyresampled($imagedst,$imagesrc,0,0,280,450,1488,1488,1488,1488)

But look here: http://www.johnconde.net/blog/cropping-an-image-with-php-and-the-gd-library/
I think that what you want is:

imagecopy($imagedst,$imagesrc,0,0,280,450,1488,1488)
