# ImageGif

ImageGif -- output image to browser or file

## Description

`int imagegif`(int im, string filename);

imagegif() creates the GIF file in filename from the image `im`. The `im` argument is the return from the imagecreate() function.

The image format will be GIF87a unless the image has been made transparent with imagecolortransparent(), in which case the image format will be GIF89a.

The filename argument is optional, and if left off, the raw image stream will be output directly. By sending an image/gif content-type using header(), you can create a PHP script that outputs GIF images directly.

> Note: Since all GIF support was removed from the GD library in version 1.6, this function is not available if you are using that version of the GD library.
