Purpose:
new features
Description:
1. add an option to convert HDF4 file without HDF4 specified attributes such as
HDF4_OBJECT_TYPE, HDF4_REF_NUM etc.
it can be done by inputting "h4toh5 -na input.hdf"
The default converter will still keep HDF4 specfied attributes.
2. Add compression features (gzip) for image too. Now the compressed HDF4 image
can be supported by using HDF5 gzip. Not sure whether tools can read it. Need to be tested.
3. Change SPACEPAD to NULLTERM for HDF4 dimensional name list. We can use variable length HDF5 string to represent these names, however currently H5dump and H5view cannot support variable length HDF5 string. converter will wait for other tools' update.
Solution:
Platforms tested:
eirene(Red Hat 6.2) and arabica(solaris 2.7)

Description:
|
|
|
|
1. converter
|
|
|
|
See HDF4 to HDF5 mapping specification at
|
|
(http://hdf.ncsa.uiuc.edu/HDF5/papers/h4toh5) for the default mapping
|
|
from HDF4 object to HDF5 object.
|
|
|
|
The whole converter includes 10 files, h4toh5util.h, h4toh5main.h, h4toh5util.c, h4toh5main.c, h4toh5sds.c, h4toh5image.c,h4toh5vdata.c,h4toh5vgroup.c,h4toh5pal.c and h4toh5anno.c.
|
|
|
|
2. this file
|
|
|
|
including declarations of subroutines of all .c files excluding h4toh5util.c.
