Implements com.sun.javafx.iio.ImageLoader.load.

Doc from com.sun.javafx.iio.ImageLoader.load.

Loads the image at a given index in an image stream. If no image exists at that index null will be returned.

Parameters
imageIndex:int

the zero-relative index of the image to load.

w:double

the desired image width. If non-positive, an IllegalArgumentException will be thrown.

h:double

the desired image height. If non-positive, an IllegalArgumentException will be thrown.

preserveAspectRatio:boolean

whether to preserve the width-to-height ratio of the image.

smooth:boolean

whether to use a smooth downscaling algorithm.

screenPixelScale:float

screen pixel scale (used for variable-density images)

imagePixelScale:float

image pixel scale (used for fixed-density images)

Returns:ImageFrame

the image at the specified index or null on error.
