Specify Loading and Rendering Options

Before loading any images, specify desired loading and rendering behavior for thumbnails as follows:

Set PreserveBlack, if desired, to darken lines in the thumbnail image. This is useful to improve readability/recognizability of the thumbnail image to the end-user.

Set CameraRaw, if desired, to specify whether the control will examine the image on loading to determine if the image data is in a camera raw format, and to identify that format. To optimize performance, CameraRaw should be set to false when not needed.

CameraRaw is only applied when the images are loaded from a local file.
