GD help

[Cam]

Hey,

I downloaded a script to turn some text into an image but I can't get it to work. Here is the script I have uploaded - http://djclan.auscstrike.com/image.php - and here is the code

<?php
function text2image($mytext,$imwidth,$imheight) {
 if (!empty($mytext)) {
  if (empty($imwidth)) $imwidth=500;
  if (empty($imheight)) $imheight=400;
  Header("Content-type: image/Jpeg");
  $im = @ImageCreate ($imwidth=500, $imheight) or die ("Cannot Initialize new GD image stream");
  $background_color = ImageColorAllocate ($im, 255, 255, 255);
  $text_color = ImageColorAllocate ($im, 0, 0, 0);
  $mytext = stripslashes($mytext);
  $mytext = ereg_replace("\r\n","\n",$mytext) ;
  $count=5;
  $returns = explode("\n", $mytext);
  while(list($k, $mytext) = each($returns)) {
   $count = $count;
   $insert_text = substr($mytext, 0);
   ltrim($insert_text);
   ImageString ($im, 2, 5,$count, $insert_text, $text_color);
   imagerectangle ($im, 2, 2, $imwidth-2, $imheight-2, $text_color);
   $count=$count+13;
  }
  ImageJpeg($im);
  ImageDestroy;
 }
}
text2image("Hello World", 130, 20);
?>

Anyone have any ideas?

Thanks

$insert_text = substr($mytext, 0);

Should that not be ...

$insert_text = substr($returns, 0);

???

one question.

why are you using a string-line-break-write script to write 'hello world' on one line.

try losing all the string manipulation first and see what happens. It is a lot easier to debug a bare-bones version than a bloated one.

Header("Content-type: image/jpeg" );
$im = @ImageCreate (300, 30);
$background_color = ImageColorAllocate ($im, 255, 255, 255);
$text_color = ImageColorAllocate ($im, 0, 0, 0);
$mytext = 'Hello World';
ImageString ($im, 2, 5, 5, $my_text, $text_color);
ImageJpeg($im);
ImageDestroy($im);

OK, I tried your code pootergeist and I've come to the conclusion that my host doesn't support GD

I'm not sure why the code as bloated but I downloaded the script as I have no clue how to work any of the image functions.

Thanks for the reply
