Parameters

[in]	ix	Pixel index in first dimension (starting from 0).
[in]	iy	Pixel index in second dimension (starting from 0).
[in]	iz	Pixel index in third dimension (starting from 0).
[in]	it	Pixel index in forth dimension (starting from 0).

Provides access to a pixel of a 4D image. No range checking or image dimension verification is performed. Use the at(ix,iy) method if range checking and image dimension verification is required.
