The ImagXpress® control provides advanced image display features. The following properties will alter the display of an image after it loads, without changing the image itself. These operations are faster than actually changing the image data and not permanent. They are particularly useful when using multiple views of one image. In that case, an operation on the image data would affect all views of that image buffer, while these operations will only affect one view.

The ImageXView methods modify only the image view, not the image itself. To modify the image, use the Processor methods. |
Anti-Aliasing Effect
The ImageXView.Antialias property enables or disables the anti-alias effect. When the logical size of an image is reduced to less than the actual size of the image, then some of that image’s pixels will be lost. When Antialias is enabled, the pixels that would occupy the same area are averaged together; turning them into a level of gray for black and white images. For color images, all of the pixels are averaged. This prevents fine lines from being lost and allows a full page of printed text to be read clearly.
Brightness
The ImageXView.Brightness property sets the brightness level for the image. It allows the user to adjust the brightness of the displayed image.
Contrast
The ImageXView.Contrast property sets the contrast level for the image. It allows the user to adjust the contrast of the displayed image.
Gray Mode
The ImageXView.GrayMode property specifies whether a grayscale image should be displayed using a medical grayscale transform or a simple linear transform.
Smoothing
The ImageXView.Smoothing property enables or disables the view smoothing effect. When the logical size of an image is increased to more than the actual size of the image, the image starts to look boxy. When Smoothing is enabled, ImagXpress performs a leveling algorithm that evens out square edges.
Dithering
The ImageXView.Dithered property enables or disables the use of dithering.
PreserveBlack
The ImageXView.PreserveBlack property enables or disables the preserve black features, which enhances black objects (such as lines) to increase readability.
