	)		const

Return a subvolume of this PixelBox.

Parameters

def	Defines the bounds of the subregion to return
resetOrigin	Whether to reset left/top/front of returned PixelBox to zero together with adjusting data pointer to compensate this, or do nothing so that returned PixelBox will have left/top/front of requested Box

Returns

A pixel box describing the region and the data in it

Remarks

This function does not copy any data, it just returns a PixelBox object with a data pointer pointing somewhere inside the data of object.

Exceptions

Exception(ERR_INVALIDPARAMS)
