Members

Rows

Number of rows of the Image.

Cols

Number of columns of the Image.

BandsPerPixel

Number of rows of the Image.

BitsPerBand

Number of columns of the Image.

ColorSpace

An enumerated value corresponding to a color space. E.g. RGB for a 3 band true color image, or Gray for a one band grayscale image.

Elevation services usually come with a colorspace value of Other.

DataType

An enumerated value corresponding to a pixel data type. E.g. UInt8 for an 8 bit image, or Elevation for 32bit elevation data.

ColorMap

A pointer to a color map for a raster. This is rarely used.
