ASCII Artwork Generator from image file

2008/09/23 07:55 in PHP

Now a days, we don't use ASCII Artwork usually for internet communication, because technology is changing rapidly.

Following snipet is the really great source can generage ASCII Artwork from image file such as jpeg or gif.

<?php
     $filename = $_POST['file'];

     $image = file_get_contents($filename);

     $image = imagecreatefromstring($image);

     $width = imagesx($image);
     $height = imagesy($image);

     $m_aspect = 164.0 / 48.0;
     $i_aspect = $width / $height;

     if($i_aspect < $m_aspect)
     {
          $percent = 48.0 / $height;
          $new_height = $height * $percent;
          $new_width = 11.875 * $new_height / 6.0 * $width / $height;
     }
     else
     {
          $percent = 164.0 / $width;
          $new_width = $width * $percent;
          $new_height = 6.0 * $new_width / 11.875 * $height / $width;
     }

     $image_p = imagecreatetruecolor($new_width, $new_height);
     imagecopyresampled($image_p, $image, 0, 0, 0, 0, $new_width, $new_height, $width, $height);

     for($i = 0; $i < $new_height; $i++)
     {
          $rgb = ImageColorAt($image_p, 0, $i);                              // OPTIMIZED
          $r = dechex(($rgb >> 16) & 0xFF);                              // OPTIMIZED
          $g = dechex(($rgb >> 8) & 0xFF);                              // OPTIMIZED
          $b = dechex($rgb & 0xFF);                                   // OPTIMIZED
          echo '<font color="#' . $r . $g . $b . '">' . strtoupper(dechex(rand(0, 15)));     // OPTIMIZED
          for($j = 1; $j < $new_width; $j++)
          {
               $rgb = ImageColorAt($image_p, $j, $i);
               $r = dechex(($rgb >> 16) & 0xFF);
               $g = dechex(($rgb >> 8) & 0xFF);
               $b = dechex($rgb & 0xFF);
               if(strlen($r) < 2)
               {
                    $r = '0' . $r;
               }
               if(strlen($g) < 2)
               {
                    $g = '0' . $g;
               }
               if(strlen($b) < 2)
               {
                    $b = '0' . $b;
               }
// NO OPTIMIZATION     echo '<font color="#' . $r . $g . $b . '">' . strtoupper(dechex(rand(0, 15))) . '</font>';
               if($rgb != ImageColorAt($image_p, $j - 1, $i))                    // OPTIMIZED
               {                                             // OPTIMIZED
                    echo '</font><font color="#' . $r . $g . $b . '">';          // OPTIMIZED
               }                                             // OPTIMIZED
               echo strtoupper(dechex(rand(0, 15)));                         // OPTIMIZED
          }                                                  // OPTIMIZED
          echo '</font>';                                             // OPTIMIZED
          echo '<br>' . "\n\n";
     }

     imagedestroy($image);
     imagedestroy($image_p);
?>
