Description:
------------
I am trying to resize an image. The image (jpg/jpeg) to be resized is of 1425 X 1425 dimesion. The image is not created from the source file using imagecreatefromjpeg() function. If I choose an image of smaller dimention (have tried with image with 800 x 600 size), then the it is being resized. The same was not happenning when I was using PHP 4.3.8. Now I have upgraded my PHP to 4.4.1. Is it a limitation in this version of PHP. Please help.... its urgent. Even an image with 1200 x 800 is not resized

Reproduce code:
---------------
$srcImage = imagecreatefromjpeg($src_file)

$ptrImage = imagecreatefromjpeg($ptr_file);

$dstImage = imageCreateTrueColor($dst_w, $dst_h);

imageCopyResampled($dstImage, $srcImage, 0, 0, 0, 0, $dst_w, $dst_h, $src_w, $src_h);

$ptr_white = imageColorAllocate($ptrImage,255,255,255);

imageCopyMerge($dstImage, $ptrImage, $ptr_x, $ptr_y, 0, 0, $ptr_w, $ptr_h, 100);

imagejpeg($dstImage, $save_path, 100);
