JPEG2000 images

Post by Kristoffer Jose on Tue Oct 27, 2015 6:22 am

Newer PopCap games such as Peggle and Bejeweled 3 use a format called JPEG2000.

JPEG2000 is a wavelet-based lossy compression format which is also used in digital cinema.

JPEG2000 and regular JPEG are neither backwards nor forwards-compatible with each other.

To check whether a PopCap game supports JPEG2000, look for j2k-codec.dll or anything related to it in the game's installation directory. If you find one, that game supports JPEG2000, otherwise, it does not.

Adding the said DLL to a game that does not have the codec will not work. On those games, you must convert such images to PNG (recommended), JPG, or GIF (not recommended) format before use.
