# image2wbmp

(PHP 4 >= 4.0.5, PHP 5)

image2wbmp -- Output image to browser or file

## 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.
