javax.imageio.spi.IIOServiceProvider

javax.imageio.spi.ImageInputStreamSpi

it.geosolutions.imageio.stream.input.spi.URLImageInputStreamSpi

All Implemented Interfaces:

RegisterableService

public class URLImageInputStreamSpi
extends ImageInputStreamSpi

Implementation of an ImageInputStreamSpi for instantiating an ImageInputStream capable of connecting to a URL.

I basically rely on the existence of something to read from a File in case this URL points to a File, otherwise I try to open up an InputStream and I ask the ImageIO.createImageInputStream(Object) to create an ImageInputStream for it.
