PHP: imagegif

(PHP 4, PHP 5, PHP 7, PHP 8)

imagegif — Output image to browser or file

imagegif() creates the GIF file in file from the image image. The image argument is the return from the imagecreate() or imagecreatefrom* 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.

A GdImage object, returned by one of the image creation functions, such as imagecreatetruecolor().

The path or an open stream resource (which is automatically closed after this function returns) to save the file to. If not set or null, the raw image stream will be output directly.

Returns true on success or false on failure.

However, if libgd fails to output the image, this function returns true.
