What do you mean by crop the bkf file data of image file?  Do you want to remove the jpeg file from the .bkf file?  If so, this cannot be done.

no I doesnot mean that. I mean if I want to extract jpg file from my bkf file. but since it is compressed i cannot recover it so can you help me tell about compressed bkf format and it algorithm

To recover the jpeg file, just restore it.

The internal structure of the .bkf files are not published.  As such, you are on your own.
