Overview of the ImageTools Package
Accessing Package Commands
List of Package Commands
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.
The long form, ImageTools:-command, is always available. The short form can be used after loading the package.
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.

The ImageTools:-Draw subpackage provides primitives for drawing into an ImageTools:-Image.
The following is a list of available commands.

The following commands in the ImageTools package are not available on Apple Silicon Macs when running native binaries. In order to use ImageTools start the Intel x86-64 version of Maple. For more information, see Platform Specific Issues.
