---|---|---|
clip | Determines whether features are clipped at the current extent boundary in the viewer. If no clipping is used, features partially within the envelope are extracted in their entirety. If clipping is used, features are extracted based on the current extent boundary. Note that none of a layer's database values are prorated for any clipped features. | |
codepage | When codepage is used, all text fields in the extracted DBF file are encoded in the given codepage, and the codepage value is stored in a CPG file. The CPG file is included in the ZIP file. If no codepage value is used, no CPG file is generated, and the sytem default codepage is used to encode text fields in the DBF file. |
