    half the size?



    guess I'll have to get glasses.

        PNG? How does it compare to JPEG? PNG is supposed to replace GIF, not JPEG...

          TIFF can come compressed in several ways.

          Anyway, didn't read the spec for this new Microsoft format, but I was always thinking that a good format could be built around separating the image into different objects, as opposed to pixel-by-pixel compression. Sort of like how bitmap-to-vector software scans the bitmap for lines and then describes them mathematically, thus using much less data. For example, most pictures have some sky for background. Sky can already be compressed pretty well since it's mostly one or two colours. But, if the algorithm would first find the boundaries of the area which is sky and then calculate the equivalent light source (position, strength, color) then maybe the sky could be described mathematically with those parametres and the basic desription be fit into only a couple of bytes. Same for grass, I mean how many different types of grass are there anyway? Enumerate them, classify them, and when a picture is taken just record "grass 7235" + some other parametres to adjust it. Just thinking out loud.

            Licensing details for the technology are still being ironed out. These could be a concern, Crow acknowledged, but "the philosophy has been that licensing should not be a restriction" to adoption, he said.

              thats not what will happen, they'll get you on the software to display and print the photos, and in the cost of the camera that can take such photos.

              or they could make an open and free standard in the decision that they need something capable of knocking out JPEG. That specification suggests that they might.

                JPEG's should not be used for printing, but a lot of people do it - thinking its alright.

                I was wondering when the next best image format will take JPG's throne, I had started to think JPG would be around forever.
                Sn00py explains why I have interest in this pretty well.

                The thing is, sometimes while laying out many advertisemets, InDesign runs a bit slower. If there is not noticable quality loss with this new format, then that would make things much easier since there wouldn't be as much as a slowdown while I'm working.

                  JPEG2000 is under patent litigation (why do you think no one uses it), and is computationally very expensive (one reason cameras never use it).

                      Are you saying that this new MS product is Open Source and free for everyone to use ?

                        Patent litigation has nothing to do with being open source or free to use.

                          Nope, but the patent usually means you have to pay for the license.

                          If you have to pay for this new MS product, then what is the difference ?

                            A patent means you reserve the right to charge people for it, not that you have to.

                            There are many patents used in Linux and other free software, for example...

                              The reason why JPEG2000 isn't being adopted is because if people do implement it, they may have to pay retroactive license fees.

                              If MS makes its licensing structure clear from the beginning, it's in a very different boat.

                                Well, when the pending patent case for jpeg2000 is ended, then there are no differences except in quality (and what you might have to pay - unless I'm wrong, the jpg license isn't cheap).
