Jpeg2000

[gicio]

am trying to load JPEG2000 (J2k) image and make use of the scalability features provided by J2k
by showing the image while loading. The tutorials clearly show that there are two possible “modes”:

- Progressive by resolution (You load the picture and it becomes sharper while loading, something
like interlaced GIF)

- Progressive by accuracy (ROI – region of interest)



I am interested in the first: “Progressive by resolution”. So I want to show the image while loading
for example if you download a 2 MB image through Modem connection.



I am looking for a exemplary implementation - does not matter in which language or platform it is running.



I would be grateful for any help.



Regards,


gicio

Perhaps you should instead of using the underused JPG2000 technology, you should use PNG technology, it's been around for a lot longer, and although not all browsers support it, it combines the small file size of the GIF format and the JPG's level of detail.

It works in a similar way to GIF's but the files are more suited to fine detail, rather that simple images.
