Synopsis

HxImageRep HxRestrict (HxImageRep img, HxPoint begin, HxPoint end)

Input

HximageRep img

The image you want to restrict to a part of the image.

HxPoint begin

The begin point of the area that should be cut out of the input image.

HxPoint end

The end point of the area that should be cut out of the input image.

Return value

HxImageRep

An image containing the area (as described by `begin' and `end') from the input image.

Description

The function HxRestrict cuts an area from the input image and returns that area as an image. This rectangular area is characterized by `begin' and `end', where every component of `end' should be larger or equal to the corresponding component of `begin'. `begin' and `end' should be valid positions in the input image.

Remarks

Valid image types

This function accepts all types of images.

Valid parameters

`begin' and `end' should have the same dimensionality as the pixel domensionality of the input image. Both points should be valid positions in the input image. Every component of `end' should be larger or equal to the corresponding component of `begin'.
