The HDF Java Products web page is located here: http://www.hdfgroup.org/hdf-java-html/ This release can be obtained from the HDF Java Products web page, as well as the HDF Downloads page at: http://www.hdfgroup.org/downloads/index.html HDF Java Products 2.6.1 includes bug fixes, new features, a test suite, and improved documentation. For more information about this release, see: http://www.hdfgroup.org/hdf-java-html/hdfview/UsersGuide/ug01introduction.html#ug01release Platforms Tested ---------------- This release was built and tested for the following platforms: 32-bit distribution -- runs on 32-bit systems or 64-bit systems with 32-bit JRE * Linux * Mac Intel * Solaris * Windows 64-bit distribution -- runs on 64-bit systems with 64-bit JRE * Linux x86_64 * Linux ia64 * Mac Intel * Solaris 64-bit Major Improvements ------------------ * Memory leak fixed in the HDF-Java native. * Added H5.getOpenIDCount() and H5.getOpenID() to track any open IDs. These functions can be very useful for checking memory leaks for applications. * Added features to show data pointed to by object references and region references. * Added find/search dataset from HDFView. * Added user option to open a file directly with read-only mode. * It now shows unsigned 64-bit integer. * It supports netcdf3 files for the NETCDF module (ncsa.hdf.object.nc2.NC2File). Major Bug Fixes --------------- * HDFView: Incorrectly displays data-type: character array * HDFView: if change palette then flip image, original colorscale is used * Local version of HDFView doc has broken links etc. * HDView: indices changed between 2.3 and 2.4. Why? * HDFView does not show preceding spaces for attribute values that begin with spaces * HDFView uses incorrect image values * HDFView: "Show Value" is always 0 if show image for 32-bit unsigned array * HDF4 object package failed on reading data * Incorrect Size of variable length dataset * Problem on import/export strings in compound datasets in HDFView * HDFView doc does not mention can save to PNG, GIF, BMP * HDFView: rainbow palette selection is different depending on where it is selected * Remove HDFCDataTypes from web page * HDFView: can't view contents of group if has same name as file * HDFView - Get error if open a compound dataset with string and reference * H5Sselect_hyperslab parameter order in header comment is wrong * High dim label is wrong * 16-bit and 32-bit images do not scale properly if set range * Use better memory allocation in HDF4 JNI to avoid crash on OutOfMemory error on large dataset. * Show some HDF-EOS attributes stored in HDF4 vdata. * Fix a problem of displaying information for HDF4 vdata without name. * Add HDF-Java logging levels to HDF5 JNI and set default level to "SEVERE". ------------------------------------------------------------- For questions regarding these or other HDF issues, contact: help@hdfgroup.org
