image.copy

image.copy is a function that is part of image.

The function returns a copy of the input image scaled to fit the specified pixel width and height.
The width and height default to the size of the input image.
The routine raises an error if the new width or height are less than or equal to 0 or greater than 25000.
This routine raises an error if there is insufficient memory to create the new image.

This has been introduced in TI-Nspire OS 3.0 (Changes).
