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.
Note:
The optional chunk_size and
type parameters became available
in PHP 4.3.2.
Note:
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.
Note: This function requires GD 2.0.1 or later (2.0.28 or later is recommended).
