Purpose:
user reported a bug on h5 to gif tool
Description:
h5 to gif did not read an HDF5 image correctly
Solution:
updated the program so that it reads the updated HDF5 image format to the latest specification
the debug version of MSVC was giving a failure on the write of the GIF file,
regarding the GIF file pointer
this write error is eliminated declaring that pointer a global variable
there is still an applicattion error on the exit of the program, only on the debug version of MSVC
Platforms tested:
w2000
Code cleanup
Description:
Windows is generating hundreds of warnings from some of the practices in
the library. Mostly, they are because size_t is 32-bit and hsize_t is
64-bit on Windows and we were carelessly casting the larger values down to
the smaller ones without checking for overflow.
Also, some other small code cleanups,etc.
Solution:
Re-worked some algorithms to eliminate the casts and also added more
overflow checking for assignments and function parameters which needed
casts.
Kent did most of the work, I just went over his changes and fit them into
the the library code a bit better.
Platforms tested:
FreeBSD 4.4 (hawkwind)
Code cleanup for better compatibility with C++ compilers
Description:
C++ compilers are choking on our C code, for various reasons:
we used our UNUSED macro incorrectly when referring to pointer types
we used various C++ keywords as variables, etc.
we incremented enum's with the ++ operator.
Solution:
Changed variables, etc.to avoid C++ keywords (new, class, typename, typeid,
template)
Fixed usage of UNUSED macro from this:
char UNUSED *c
to this:
char * UNUSED c
Switched the enums from x++ to x=x+1
Platforms tested:
FreeBSD 4.4 (hawkwind)
More code cleanups
Description:
Wrap up the code cleanups for changing the dataset transfer property lists
over to using the generic property list code.
Platforms tested:
IRIX64 6.5 (modi4)
Code cleanups, mostly..
Description:
Work on pacifying the SGI compiler to get the generic properties working
correctly with --enable-parallel and --enable-fortran. It's not quite
fixed yet, but I need to head home and these patches help... :-/
Platforms tested:
IRIX64 6.5 (modi4)
Purpose:
Reformatting
Description:
Reformatted the code so that it's much clearer and conforms to the
HDF5 coding standards. Changed the function headers to use the ANSI
style instead of the KnR style. Kept the use of typedef's such as
"unsigned char" being "BYTE" and so on since of of this code is
copied from some other place and that's the style they use...I didn't
want to break things.
Platforms tested:
It compiles fine on Linux, but there aren't any tests for this
package, so...
Purpose:
Bug fix (by Bob McGrath)
Description:
On Solaris platforms palette was not written to the HDF5 file
Solution:
'\0' character was written outside the GroupName array. Apparently on Solaris it destroyed the condition value that determined if the palette should be written to the file.
Platforms tested:
Not tested yet.
Purpose:
Bug fix
Description:
One of the function calls (H5Sget_simple_extent_dims) used parameter with
the wrong type. That caused compilation errors on T3E.
Solution:
Used NULL since that argument is optional and was never used.
Platforms tested:
T3E(mcurie) and IRIX64 (modi4)
Purpose:
Bug fix
Description:
Rushabh added new directory tools/gifconv to CVS. He also modified
MANIFEST, but bin/chkmanifest complains this file.
Solution:
I will try to delete gif.h and then to add it once more.
Purpose:
Adding new feature
Description:
Added gif2h5 and h52gif conversion utilities
Solution:
The utilites follow the framework built for the gif2hdf and hdf2gif
utilities for hdf4. The main files modified were those that read the
H5 file and those that write H5 file. In the future, if you wish to
continue with the framework and extend it to .png or some other fileformat
the main files to edit will be the gif reader and writer.
One point to note with h52gif. You have to specify the exact location of
the image and the palette that it links to. You can choose not to specify
a palette (uniform grayscale chosen in this case) but you must specify
image location. In the future, someone could edit the readhdf.c source
to enable the reader to parse the hdf file and select all images with
corresponding palettes.
Platforms tested:
modi4 , eirene , hawkwind , arabica , Ren (NT 4.0) , Personal box (win2k)
