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 imagecreate().
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.
