> Currently clerezza uses Java Image IO to read images and create
> BufferedImages. This is done in various places such as the
> ImageMetaDataGenerator and the AlternativeRepresentationGenerator. However
> the Java ImageIO implementation can fail with some JPEGs that have certain
> meta data stored that does not conform exactly to JPEG specification. In
> order to handle such cases there should be a possibility register other
> libraries or implementations that generate BufferedImages and handle these
> cases.
> I suggest to create a BufferedImageProvider OSGi service and use it in the
> meta data generators mentioned above. There should also be a default
> implementation of this service that uses Java ImageIO. Clients should then be
> able to register services that override this service and may have different
> implementations that return BufferedImages. I think it might work with the
> service-ranking property but I am not sure.
