It seems that .NET can't open JP2 (Jpeg 2000) files using the GDI library. I've searched on google but can't find any libraries or example code to do this. Anybody got any ideas? I don't really want to pay for a library to do it unless I have to.. ...
I have written code to compress and decompress image files using a proprietary SDK for transmission from an aircraft via satellite. Unfortunately a license must be purchased for decompression as well as compression. Until now my applications have been mostly used in-house so I can keep track of the licenses and distribution. Now I need...
I need to encrypt a lot of large JPEG files. The pictures are very sensitive and need to only be decrypted inside my application. Because of the number and size of the images, speed is an issue. ...
I've seen JPEG2000 files with both .J2K and .JP2 extensions, and codecs which read one won't always read the other. Can someone explain why there are multiple extensions for what I thought was a single format? ...

I need to handle JPEG 2000 (aka J2K) images in my silverlight app. Files stored either in the DB or file system on the server. Any suggestions how to handle them on the client? The only working converter I came across was written in Java. There are some ports to J#, but most likely they are not going to work on the client. The requiremen...

One of the nice features of JPEG 2000 is that it's easy to downres an image -- just feed out fewer bytes. Is there a similar way to scale the image, such that I could send a thumbnail using bytes in the full-size file, without resampling? ...

I'm especially interested to find out if there's a common way to access any "multiple-size" (e.g. 2k/4k) image data which might exist. ...
I'm new to Java. I've been able to read a "raw" image file with short data, display it, and save it as a .jp2 file but the 150.000 byte file gets compressed to just over 50,000 bytes. Some years ago I used a propriatry library to in C/C++ to do this and achieved lossless compression of the same type of images in the range of 10:1. My ...
Hi, i'm experiencing some problems with the JPEG-2000 file format and Imagemagick. First of all i needed to identify a jpf file, i couldn't get this to work after lots of tries, any idea if this is supported?
