If I remember correctly you just set the output file header's compression information to B44 and write the image to disk.

Anybody out there who has the remotest clue about how I am supposed to get
images compressed using B44 compression through my C++ code?

Any help will appreciated.

Hi,

Can some one please tell me about how and at what point the B44 compression of an image takes place? I have searched online and have not found anything
clarifying this matter including the docs. I'm currently under the
impression that the only thing I can do to accomplish this task is
specifying the particular compression flag in the header that is generated while saving an exr image. And could I also know if there are any libraries out there that will enable me to compress an image using the B44 method in
C++.
 What I am trying to do is use a sequence of frames to play a video
directly from the disk(like 'playexr') where the frames are in dpx format. Thus I need to convert the images into B44 compressed exr's and use them to play the video. I used ImageMagick for the conversion but I have not been able to compress them because for some reason, IM will not compress them in
spite of using the correct commands and their error free execution.
