org.apache.xmlgraphics.image.loader.ImageInfo
Represents an image that may not have been fully loaded. Usually, the loading only goes as far as necessary to know the intrinsic size of the image. The image will only fully loaded later when the image needs to be presented in a particular format so the consuming component can actually process it. The "preloading" is done so a layout engine can work with the image without having to fully load it (in memory).
