(See #!Limport,dxall871 h Import #!EL in IBM Visualization Data Explorer User's Reference.) #!N #!I30 #!N o Write your own import module to read the data and create a Data Explorer Object as its output (e.g., a Field Object). #!N #!I0 #!N #!EF #!N #!N #!N #!I0 #!N Notes: #!N #!I30 #!N 1. The following examples illustrate the conversion of data from Hierarchical Data Format (HDF) to Data Explorer file format. Understanding the examples does not require any familiarity with HDF. #!N #!I30 #!N 2. HDF libraries are not distributed with Data Explorer and no makefiles are provided for the programs used. If you have the HDF libraries, you can use the same compilation and linking procedures as you do for other programs requiring those libraries. #!N #!I30 #!N 3. The Import module will import HDF data. The example in #!Lwrimp,dxall1038 h Writing an Import Module #!EL is for illustration only. #!I0 #!N #!N #!N #!N #!N #!F-adobe-times-medium-i-normal--18* Next Topic #!EF #!N #!N #!Lall1036,dxall1037 h Writing a Filter #!EL #!N #!F-adobe-times-medium-i-normal--18* #!N
