The following sections describe attributes, child elements, and parent elements.

Attributes

Attribute

Description

Width

Required double attribute.

The width of the area of the image displayed. This value is in logical coordinates. For example, a value of 1 displays the entire image (no zoom), a value of 0.5 is 200% zoomed in, and a value of 0 is completely zoomed (user cannot see the image at all). A value above 1 is zooming out from the image. For example, a value of 2 means that the image will take up half the size of the MultiScaleSubImage control area (50% zoom).

X

The left coordinate of the rectangular area of the image to be displayed. The coordinates of the point are in local coordinates (0-1) relative to the displayed image width.
