# 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 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.

Beispiel 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 ?>`

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