Wow, pretty cool.
Is the source available? I'm always very curious how such things work. I've never worked with images in php before.

Most code is purely gzipping, but oh well

Code Select

Zef You should make that Yabb Compatible so u can do it in the forums, make another php file:

Code Select

<?php  /**  * Checks if user accepts gzipped output, and if zo compresses the output  * @param $text text to compress  * @param $level compression level (1 is recommended)  */  function gzip($text, $level=1)  {    global $TS, $DB;    global $HTTP_ACCEPT_ENCODING;    // Check if zlib is installed    if(function_exists("crc32") && function_exists("gzcompress"))    {      // if so check what kind of gzipping can be used      if(strpos(" ".$HTTP_ACCEPT_ENCODING, "x-gzip"))        $encoding = "x-gzip";      elseif(strpos(" ".$HTTP_ACCEPT_ENCODING,"gzip"))        $encoding = "gzip";      if ($encoding) // ok, encoding is accepted      {        header("Content-Encoding: $encoding");        $size = strlen($text);        $crc = crc32($text);        $output = "\x1f\x8b\x08\x00\x00\x00\x00\x00";        $output .= substr(gzcompress($text, $level), 0, -4);        $output .= pack("V", $crc);        $output .= pack("V", $size);      }      else         $output = $text;    }    else      $output = $text;    echo $output;  }ob_start();if(!$url)   $img = "andrea2.png";else{   $rf = fopen($url, "rb") or die("Could not open file $url");   $buffer = "";   while($buf = fread($rf, 1024))      $buffer .= $buf;   fclose($rf);   $fd = fopen("image.png", "wb") or die("Could not open image.png for writing");   fwrite($fd, $buffer);   fclose($fd);   $img = "image.png";}$imgHand = ImageCreateFromPng($img); $imgSize = GetImageSize($img); $imgWidth = $imgSize[0]; $imgHeight = $imgSize[1]; $htmlCode = "[font=Courier]"; for ($l = 0; $l < $imgHeight; $l++) {     $htmlCode .= "<br>\n";     for ($c = 0; $c < $imgWidth; $c++) {         $pxlCor = ImageColorAt($imgHand,$c,$l);         $pxlCorArr = ImageColorsForIndex($imgHand, $pxlCor);         $htmlCor = DecHex($pxlCorArr["red"]) . DecHex($pxlCorArr["green"]) . DecHex($pxlCorArr["blue"]);         $htmlCode .= "[color=#$htmlCor]#[/color]";     } } $htmlCode .= "[/font]"; print <<<EOT<html><head>   <title>PNG 2 ASCII: $img</title></head><body bgcolor="#000000"><form method="GET"><font color="#FFFFFF"><b>URL:</b> <input type=text name="url" value="http://www.fmf.nl/~zef/andrea2.png"> (PNG images only!)</font><br><input type=submit value="View"></form>EOT;print $htmlCode; print "</body></html>";$html = ob_get_contents();ob_end_clean();gzip($html, 1);exit();?>

I could, but every message the script would be generate would exceed the message limit so it's no use
