Description
int
image2wbmp ( resource image [, string filename [, int threshold]] )
image2wbmp() creates the
WBMP file in filename from the image
image. The image argument
is the return from one of the image create functions, such as
imagecreatetruecolor().
The filename argument is optional, and if left off, the raw image
stream will be output directly.
By sending an image/vnd.wap.wbmp content-type
using header(), you can create
a PHP script that outputs WBMP images directly.
Example 1. image2wbmp() example
<?php
$file = 'php.png';
$image = imagecreatefrompng($file);
header('Content-type: ' . image_type_to_mime_type(IMAGETYPE_WBMP));
image2wbmp($image); // output the stream directly
?>

Note:
WBMP support is only available if PHP was compiled
against GD-1.8 or later.
