Inputs o BMP, GIF, TIF, JPG, FPX, PNM o SVG instream and external file Output o JPEG (Acrobat Reader interprets the complete image file within a PDF file = no transformation = no lossy info loss)
Features o colors: RGB, Gray, CMYK o svg, image processing isolated in renderer XObject class o little memory requirements o process and store images and external SVG once in PDF - redisplay them in various sizes many times o parameter passing to the rrenderer XSL:FO interface By svg <desc> in order to parametrize PDF generation. If FOP let instream-foreign-objects be foreign without touching them, outlines, form fields, JavaScripts can be implemented by meaningful XML allowing unrestricted, safe extension contributions. The challenge o Handling layout size of images and svg's. o Java Advanced Imaging transforms images at load time, properties of the orignal image are distorted. Programming against the codec's might solve this problem. o Given correct properties: how to generate the precise PDF dictionary entries. For JPEG not too difficult, but other formats? Software o JRE 1.3 o Java Advanced Imaging 1.1 Hansuli Anderegg
