B44 produces fixed-size files; and some people have explicitly asked for this feature. With B44A file size can vary (but B44A files are never larger than B44 files). On systems dedicated to real-time recording or playback you may want to pre-allocate space for the images, for example, to minimize seek operations on disks. In this case you may want to use B44 compression. You could use B44A, but it wouldn't buy you anything. Florian Ken McGaugh wrote:

This is a variation of B44, but witha better compression ratio for images with large uniform areas,such as in an alpha channel.Are there any disadvantages to using B44A versus B44? Or should we just always use B44A?Thanks for a great release. I've been looking forward to this for a while.--Ken _______________________________________________ Openexr-devel mailing list address@hidden http://lists.nongnu.org/mailman/listinfo/openexr-devel
