Description

bool imagegd2 ( resource image [, string filename [, int chunk_size [, int type]]] )

- imagegd2() outputs a GD2 image to filename. The image parameter is the return from the imagecreatetruecolor() function.
- The filename parameter is optional, and if left off, the raw image stream will be output directly.
- The optional type parameter is either IMG_GD2_RAW or IMG_GD2_COMPRESSED. Default is IMG_GD2_RAW.
Замечание: The optional chunk_size and type parameters became available in PHP 4.3.2.
Замечание: The GD2 format is commonly used to allow fast loading of parts of images. Note that the GD2 format is only usable in GD2-compatible applications.
