ImageData
ImageData[
data, opts
]
is the default
ImageProcessing
data structure for monochrome and color images.
ImageData
is a new
Mathematica
object that facilitates the easy manipulation and handling of single-channel and multichannel images.
ImageData
is the default return value of the
ImageRead
function.
ImageData
has two options that define the pixel-interleaving method and the color function, respectively. The permitted values follow.
