Manual

GdImage$image,
[resource|string|null$file = null],
[int|null$foreground_color = null]
): bool
GdImage$image,
[resource|string|null$file = null],
[int|null$foreground_color = null]
): bool
imagewbmp outputs or save a WBMP version of the given image.
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.
- foreground_color
-
You can set the foreground color with this parameter by setting an identifier obtained from imagecolorallocate. The default foreground color is black.
Return Values
Returns true on success or false on failure.
Caution:
However, if libgd fails to output the image, this function returns true.
