Parameters

image

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

file

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.

quality

quality is optional, and ranges from 0 (worst quality, smaller file) to 100 (best quality, larger file). If -1 is provided, the default value 30 is used.

speed

speed is optional, and ranges from 0 (slow, smaller file) to 10 (fast, larger file). If -1 is provided, the default value 6 is used.

Return Values

Returns true on success or false on failure.

Caution

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