HDF_DFSD_STARTSLICE
This routine is obsolete and should not be used in new IDL code.
The HDF_DFSD_STARTSLICE procedure prepares the system to write a slice of data to an HDF file. HDF_DFSD_SETINFO must be called before HDF_DFSD_STARTSLICE to set the dimensions and attributes of the slice.
This procedure must be called before calling HDF_DFSD_PUTSLICE, and must be terminated with a call to HDF_DFSD_ENDSLICE.
Syntax
HDF_DFSD_STARTSLICE, Filename
Arguments
Filename
A scalar string containing the name of the file to be written.
Example
; Open an HDF file: fid=HDF_OPEN('test.hdf',/ALL) ; Create two datasets: slicedata1=FINDGEN(5,10,15) slicedata2=DINDGEN(4,5) ; Use HDF_DFSD_SETINFO to set the dimensions, then add ; the first slice: HDF_DFSD_SETINFO,LABEL='label1', DIMS=[5,10,15], /FLOAT HDF_DFSD_STARTSLICE,'test.hdf' HDF_DFSD_PUTSLICE, slicedata1 HDF_DFSD_ENDSLICE ; Repeat the process for the second slice: HDF_DFSD_SETINFO, LABEL='label2', DIMS=[4,5], /DOUBLE HDF_DFSD_STARTSLICE,'test.hdf' HDF_DFSD_PUTSLICE, slicedata2 HDF_DFSD_ENDSLICE HDF_DFSD_SETINFO, /RESTART ; Use HDF_DFSD_GETINFO to advance slices and set slice ; attributes, then get the slices: HDF_DFSD_GETINFO, name, DIMS=dims, TYPE=type HDF_DFSD_GETSLICE, out1 HDF_DFSD_GETINFO, name, DIMS=dims, TYPE=type HDF_DFSD_GETSLICE, out2 ; Close the HDF file: HDF_CLOSE('test.hdf') ;Check the first slice to see if everything worked: IF TOTAL(out1 EQ slicedata1) EQ N_ELEMENTS(out1) THEN $ PRINT, 'SLICE 1 WRITTEN/READ CORRECTLY' ELSE $ PRINT, 'SLICE 1 WRITTEN/READ INCORRECTLY' ; Check the second slice to see if everything worked: IF TOTAL(out2 EQ slicedata2) EQ N_ELEMENTS(out2) THEN $ PRINT, 'SLICE 2 WRITTEN/READ CORRECTLY' ELSE $ PRINT, 'SLICE 2 WRITTEN/READ INCORRECTLY'
