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.
