The GUI Magnifier Window

The ImGearMagnifier Class control provides a magnified view of a portion of the image in ImGearPageView Class control. It appears either in a separate, stationary window, or as a popup area within the ImGearPageView Class window. When the GUI Magnifier control is active, and the user drags the mouse within the ImGearPageView Class control, the magnified display of the image tracks the location of the mouse. If the popup view is used, the magnified display of the image tracks the mouse within the ImGearPageView Class control. The programmer can set the magnification factor, and can optionally expose that capability to the end user. If the separate, stationary window is used, the area of the image that is displayed in the floating window is displayed in reverse video in the ImGearPageView Class control. A scroll bar is provided in the magnify window. When the user drags this magnify window scroll bar, ImageGear automatically changes the magnification factor.
