||
* Purpose: Create a dataset compressed with the deflate filter.
|
||
* This program is used to create the test file `tdeflate.h5' which has
|
||
* a dataset compressed with the "deflate" I/O filter. This dataset will
|
||
* be used to verify the correct behavior of the library when a filter is
|
||
* not available for a dataset which requires it.
