load

public ImageFrame load(int imageIndex,
                       int width,
                       int height,
                       boolean preserveAspectRatio,
                       boolean smooth)
                throws IOException

Description copied from interface: ImageLoader

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

Parameters:

imageIndex - the zero-relative index of the image to load.

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

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

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

smooth - whether to use a smooth downscaling algorithm.

Returns:

the image at the specified index or null on error.

Throws:

IOException
