Combining gifs...

Subject: Combining gifs...

I have gifs named smnnnxxxxxx.gif where nnn = the Ascii
value, numbers sm32 through sm127, and xxxxxx = the
different colors yellow, aqua, white, red or lime.

example:
LimeGreen "0" = sm48lime.gif
Red "z" = sm122red.gif

I have all these gifs because I use them for a scoreboard display
with letters also.

example:

Texans 19 Cowboys 10

would show as:
<tr>
  <td>
  <img src="sm84yellow.gif" height="22" width="16"><img 
       src="sm101yellow.gif" height="22" width="16"><img 
       src="sm120yellow.gif" height="22" width="16"><img 
       src="sm97yellow.gif" height="22" width="16"><img 
       src="sm110yellow.gif" height="22" width="16"><img 
       src="sm115yellow.gif" height="22" width="16"><img           

       src="sm32yellow.gif" height="22" width="16"><img
       src="sm49yellow.gif" height="22" width="16"><img
       src="sm57yellow.gif" height="22" width="16">
  </td>
  <td>
  <img src="sm67yellow.gif" height="22" width="16"><img
       src="sm111yellow.gif" height="22" width="16"><img
       src="sm119yellow.gif" height="22" width="16"><img
       src="sm98yellow.gif" height="22" width="16"><img
       src="sm111yellow.gif" height="22" width="16"><img
       src="sm121yellow.gif" height="22" width="16"><img
       src="sm115yellow.gif" height="22" width="16"><img
       src="sm32yellow.gif" height="22" width="16"><img           

       src="sm49yellow.gif" height="22" width="16"><img           

       src="sm48yellow.gif" height="22" width="16">
  </td>
</tr>     

Basically, what I'd like to do is pass the text to a function
and have the script COMBINE the gifs to one gif and stream it
back to the browser. This function would return one gif with
that text made up from the single chars.

So the score above would be:

<tr>
  <td>
    <img src="<$=gif_Combine('Texans 19')>">
  </td>
  <td>
    <img src="<$=gif_Combine('Cowboys 10')>">
  </td>
</tr>     

How can I do that? Possible? I don't want to use a font because I
want this to look like a scoreboard at a real stadium. I have
created the gifs to look like the individual light sections that make
up the chars.

I can convert these to PNG if necessary...

Does this look OK?

function gif_Combine($text, $color) 
{
  $dx = strlen($text) * 16;
  $dy = 22;
  $im = imagecreate($dx,$dy);
  for ($count = 0; $count <= strlen($text); $count++) 
  {
    imagecopy($im,  imagegif('images/digits/sm'.ord($text[$i]).$color.'.gif'),  i*16, 0, 16, 22);
  }
  return imagegif($im);
  imagedestroy($im);
}

called like this:

<img src="<% buildgif('Texans 19', 'yellow') >">

[mrbaseball34]

OK, got this from alt.php NG.
(I added the code for defaulting the color and mystr variables)

<?php
  if (!isset($color)) {
    $color = 'yellow';
  }
  if (!isset($mystr)) {
    $mystr = 'Error';
  }   

  set_time_limit(250);
  header("Content-Type: image/gif\n\n");
  $dx = strlen($mystr) * 16;
  $dy = 22;
  $im = @imagecreate($dx,$dy);  

  for ($count = 0; $count < strlen($mystr); $count++)
  {
    $imgstr = "images/digits/sm".ord($mystr[$count+1]).$color.".gif";
    $im_tmp = @imagecreatefromgif($imgstr);
    imagecopy($im,$im_tmp,($count+1)*16, 0, 16, 22);
    imagedestroy($im_tmp);  

  }  

  ImageGif($im);
  ImageDestroy($im);   

?>

But all I get is a red 'X' image placeholder.

Any ideas?

[mrbaseball34]

Found out that my loop was incorrect and the call to imagecreatefromgif was wrong, too.

Here's a better shot but I still get the red 'X'...

Here's the HTML calling the script:

<img src="buildgif.php?mystr=buildgif">

What the heck can I be doing wrong here?

<?php
  if (!isset($color)) {
    $color = 'yellow';
  }
  if (!isset($mystr)) {
    $mystr = 'Error';
  }   

  if (isset($test)) {
    echo $color.'<br>'.$mystr.'<br><br>';
  } else {
    header('Content-Type: image/gif\n\n');
    set_time_limit(250);
    $dx = strlen($mystr) * 16;
    $dy = 22;
    $im = @imagecreate($dx,$dy);  

  }
  for ($count = 0; $count < strlen($mystr); $count++)
  {
    $imgstr = 'sm'.ord($mystr[$count]).$color.'.gif';
    if (isset($test)) {
      echo $imgstr.'<br>';
    } else {
      $im_tmp = @imagecreatefromgif($imgstr);
      imagecopy($im,$im_tmp, $count*16, 0, 0, 0, 16, 22);
      imagedestroy($im_tmp);  

    }
  }  

  if (!isset($test)) {
    imagegif($im, '');
    imagedestroy($im);   

  }
?>

I KNOW that the variables $color and $mystr are getting set
correctly. I KNOW that $imgstr is getting set correctly in the
loop and I'm getting all the right imagelinks. Use this call to test:

  buildgif.php?test=yes&mystr=buildgif
