thumbnailWidth
The desired maximum width of the thumbnail image in pixels.
thumbnailHeight
The desired maximum height of the thumbnail image in pixels.
bitsPerPixel
The desired bits per pixel.
viewPerspective
The desired view perspective.
sizeFlags
Flags that control the resize operation.
A new RasterImage that is the thumbnail image.
If the image width and height is less than thumbnailWidth and thumbnailHeight, then this method returns a copy of the image in the original size.
If the image width or height is greater than thumbnailWidth and thumbnailHeight, then this method will return the biggest thumbnail it can fit into the dimensions specified by thumbailWidth and thumbnailHeight, keeping the original image aspect ratio.
The result image will always have a resolution of 96 by 96 regardless of the resolution this RasterImage and will never return a thumbnail bigger than the original image.
