Tim, have a look at h5repack http://www.hdfgroup.org/HDF5/doc/RM/Tools.html#Tools-Repack
Before coding anything you can experiment with the chunk size and compression method/level for the image dataset. Best, G. -----Original Message----- From: Hdf-forum [mailto:[email protected]] On Behalf Of Tim Sent: Thursday, February 06, 2014 11:43 AM To: HDF Forum Subject: [Hdf-forum] Is there a best practice for storing image data to be viewed with HDFView in a space-efficient way? I am new to HDF5. Is there a best practice for storing image data to be viewed with HDFView in a space-efficient way? For example, when importing a 720 x 678 JPEG image that contains 114,173 bytes, with HDFView or a Python program, the resulting HDF5 image dataset contains 1.4 MB (720 x 678 x 3 for the RGB values = 1,464,480 bytes). What is the best strategy for compressing this data so that it can still be viewed with HDFView? Thanks for your kind consideration. _______________________________________________ Hdf-forum is for HDF software users discussion.
