Image Text Generator

@s_b37Oct 13.2007 — #It is quite complicated, because you need to specify the sizes in px of each letter, and this would probably be done through a database, which has the source and pixel width of each letter

The php manual for creating images can be found at: http://www.php.net/image.

Basically, you'll need the ImageColorAllocate, ImageCreateFromGif, ImageCopy, and ImageGif functions, but you may also need to configure your server (needs GD or something enabled).

If you get the size and source data from the database, in the form:

[code=php]$imageInfo = array(
 'a' => array(width, source),
 ...
 )[/code]

for both uppercase and lowercase (and all symbols you'll need), and store your message in $message

then this should work:

[code=php]
 // the space between each letter
 $spacing = 10;
 // we need total width when creating image
 // set the current width, to the starting space
 $width=$spacing;
 for ($char=0; $char<strlen($message); $char++){
 // adds the width
 $width += $imageInfo[$message[$char]][0];
 // add a spacing
 $width += $spacing;
 }
 
 // replace 15 with height based on images
 $img = ImageCreate($width, 15);
 // set background white, pass image reference and r,g,b values
 ImageColorAllocate($img, 255, 255, 255);
 
 $xPos = 0;
 for ($char=0; $char<strlen($message); $char++){
 $src = $imageInfo[$message[$char]][1];
 $ltrWidth = $imageInfo[$message[$char]][0];
 $letter = ImageCreateFromGif($src);
 // param order: base image, letter image, x pos in base, y pos in base, x pos in letter, y pos in letter, letter width (to copy), letter height (adjust to same as above)
 ImageCopy($img, $letter, $xPos, 0, 0, 0, $ltrWidth, 15);
 $xPos += $ltrWidth + $spacing;
 }
 
 // send the image header, you probably want a gif or a png
 header ("Content-type: image/gif");
 ImageGif($img);
 ImageDestroy($img);[/code]

Note: not tested, and code is just rough idea
