<?php

//load the image! it's possible to open remote image from another website, just put full url on it!
$img = imagecreatefromjpeg("sample-image.jpg");

//find the size of the borders
$b_top = 0;
$b_btm = 0;
$b_lft = 0;
$b_rt = 0;

//top
for(; $b_top < imagesy($img); ++$b_top) {
  for($x = 0; $x < imagesx($img); ++$x) {
    if(imagecolorat($img, $x, $b_top) != 0xFFFFFF) {
       break 2; //out of the 'top' loop
    }
  }
}

//bottom
for(; $b_btm < imagesy($img); ++$b_btm) {
  for($x = 0; $x < imagesx($img); ++$x) {
    if(imagecolorat($img, $x, imagesy($img) - $b_btm-1) != 0xFFFFFF) {
       break 2; //out of the 'bottom' loop
    }
  }
}

//left
for(; $b_lft < imagesx($img); ++$b_lft) {
  for($y = 0; $y < imagesy($img); ++$y) {
    if(imagecolorat($img, $b_lft, $y) != 0xFFFFFF) {
       break 2; //out of the 'left' loop
    }
  }
}

//right
for(; $b_rt < imagesx($img); ++$b_rt) {
  for($y = 0; $y < imagesy($img); ++$y) {
    if(imagecolorat($img, imagesx($img) - $b_rt-1, $y) != 0xFFFFFF) {
       break 2; //out of the 'right' loop
    }
  }
}

//copy the contents, excluding the border
$newimg = imagecreatetruecolor(
    imagesx($img)-($b_lft+$b_rt), imagesy($img)-($b_top+$b_btm));

imagecopy($newimg, $img, 0, 0, $b_lft, $b_top, imagesx($newimg), imagesy($newimg));

//finally, output the image
header("Content-Type: image/jpeg");
imagejpeg($newimg);

?>

He was a Carnegie Melon professor and was in his forties. Pausch died of complications from pancreatic cancer on July 25, 2008, but wrote a book “The last lecture”, one of the bestsellers in 2007. He gave an upbeat lecture titled “The Last Lecture: Really Achieving Your Childhood Dreams” on September 18, 2007, at Carnegie Mellon, which became a popular YouTube video and led to other media appearances. He then co-authored a book called The Last Lecture on the same theme, which became a New York Times best-seller. What a legacy to leave behind. In a letter to his wife Jai and his children, Dylan, Logan, and Chloe, he wrote this beautiful “Guide to a better life” for them to follow. May you be blessed by his insight.
