H5P.set_fill_value

Set fill value for dataset creation property list

Syntax

H5P.set_fill_value(plist_id,type_id,value)

Description

H5P.set_fill_value(plist_id,type_id,value) sets the fill value for a the dataset creation property list specified by plist_id. The value argument specifies the fill value. type_id specifies the datatype of the fill value. Setting value to an empty array indicates that the fill value is to be undefined.

Examples

Create a double precision dataset with a fill value of -999.

fid = H5F.create('myfile.h5');
type_id = H5T.copy('H5T_NATIVE_DOUBLE');
dims = [100 50];
h5_dims = fliplr(dims);
h5_maxdims = h5_dims;
space_id = H5S.create_simple(2,h5_dims,h5_maxdims);
dcpl = H5P.create('H5P_DATASET_CREATE');
fill_time = H5ML.get_constant_value('H5D_FILL_TIME_ALLOC');
H5P.set_fill_time(dcpl,fill_time);
type_id = H5T.copy('H5T_NATIVE_DOUBLE');
H5P.set_fill_value(dcpl,type_id,-999);
dset_id = H5D.create(fid,'DS',type_id,space_id,dcpl);
H5D.close(dset_id);
H5F.close(fid);
