ImageTools[command](arguments)
command(arguments)
The ImageTools package implements a number of image processing functions.
Within this package, image data is represented as dense rectangular Arrays of 64-bit hardware floating point numbers. Grayscale and color images can be represented; see ImageTools[ImageTypes] for descriptions of the types and data structures.
See the applications,ImageProcessing worksheet for a demonstration of the ImageTools package.
Each command in the ImageTools package can be accessed by using either the long form or the short form of the command name in the command calling sequence.
Because the underlying implementation of the ImageTools package is a module, it is possible to use the form ImageTools:-command to access a command from the package. For more information, see Module Members.
The following is a list of available commands. To display the help page for a particular command, see Getting Help with a Command in a Package.
