An internal image is a simple R object with a few attributes including a
pointer to an internal C structure, which contains the full image data. They
are used in the package for efficiency, but can be converted to a normal
R array using the as.array method. Attributes of these objects should
not be changed.
Usage
"dim"(x)
"dim"(x) <- value
"as.array"(x, ...)
Arguments
x
An "internalImage" object.
value
Not used. Changing the dimensions of an internal image is
invalid, and will produce an error.
