Members

By setting the ImageViewer.SizeMode property to one of the ImageViewerSizeMode enumeration values, the control will determine how to fit the image in the viewing area.

When using the None and ActualSize with the ImageViewer control, vertical or horizontal scrollbars may become visible and functional if the image size becomes greater than the viewing area (depending on the value of ImageViewer.ScrollMode). The image size is determined by the image physical pixel width and height and the values of the ImageViewer.UseDpi and ImageViewer.ScaleFactor properties. The ImageViewer.AspectRatioCorrection will also play a role in determining the image size of its value is other than 1. The viewing area size is determined from the current pixel size of the control client area.

When the using ImageViewer.SizeMode, the value of ImageViewer.ScaleFactor will not be reset back to 1 automatically. You can either set the value of ImageViewer.ScaleFactor to 1 if this is the required behavior or use the ImageViewer.Zoom method that will have the size mode and scale factor values to setup the current view to any desired values using one method.

For an example, see ImageViewer.Zoom.
