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.imageInfo
