Interface ImageHandler

public interface ImageHandler

Interface to tell PDFOptimizer how to handle an image. An implementations of this interface should be registered with OptSettings by calling OptSettings.setImageHandler(ImageHandler). When processing a document, the convertImage(ImageInfo) method will be called for each image found in the document. The implementation can then look at the image properties, such as size, resolution and compression to decide how to convert the image.
