    • Method Detail

      • isSupported

        public boolean isSupported​(ImageInfo imageInfo)
        Indicates whether the given image (represented by an ImageInfo object) is supported by the loader. By default, implementations return true assuming all images of the supported MIME types can be processed correctly. In some cases, however, an ImageLoader may only support a subset of a format because it offers an optimized way to embed the image in the target format (for example: CCITT compressed TIFF files in PDF and PostScript). For this to work, the preloader must register some information in the ImageInfo's custom objects so the factory can identify if an image may or may not be supported.
        Specified by:
        isSupported in interface ImageLoaderFactory
        Parameters:
        imageInfo - the image info object
        Returns:
        true if the image is supported by the loaders generated by this factory
      • getUsagePenalty

        public int getUsagePenalty​(java.lang.String mime,
                                   ImageFlavor flavor)
        Deprecated.
        Returns the usage penalty for a particular ImageLoader. This is used to select the best ImageLoader implementation for loading an image.
        Specified by:
        getUsagePenalty in interface ImageLoaderFactory
        Parameters:
        mime - the MIME type
        flavor - the target image flavor
        Returns:
        the usage penalty (must be a non-negative integer)
