Property Value

The physical view rectangle.

The physical view rectangle is the current viewing rectangle in viewer coordinates. The value of this property is current pixel location on the RasterImageViewer control of the image top, left, right and bottom pixel values.

For example, you are using RasterPaintSizeMode.Normal and the viewer has a vertical scroll bar, when the scroll bar value is at the top of the image, the Top value of PhysicalViewRectangle will be 0. If you scroll the image up (by dragging the vertical scroll bar down), the value of Top will become a negative value since the top of the image is painted outside the control coordinates.
