DecodePixelWidthWill load the BitmapImage with the specified width. Helps with memory usage and speed when loading large images that are meant to be displayed smaller on the screen. This is more efficient than loading full image and rely on the Image control to do the resize.
DecodePixelHeightSame as DecodePixelHeight. If only one parameter is specified the system will maintain the Aspect Ratio of the image while loading at the required size.
