Syntax
LONG SetRenderMode (LONG nMode)
Description
SetRenderMode() sets the way the image is scaled and displayed. Three modes of operation are available:
•Normal rendering:
The image is displayed with a scale factor of 1. If the image is larger than the display window then the image is clipped at the right and bottom side.
•Fit to display window:
The image is scaled to fit exactly in the display window. The aspect ratio of the displayed image may not be identical to the aspect ratio of the original image. Therefore objects may appear stretched or shrinked.
•Downscale 1:2:
The image is displayed with a downscale factor of 2. If the scaled image is larger than the display window then the image is clipped at the right and bottom side. This mode is not supported when using Direct3D.
