    EsriShapeExportFlags Enumeration
    In This Topic
    Specifies the flags that control the behavior of the GeometryEngine.ExportToEsriShape and GeometryEngine.ExportToEsriShape methods.
    EsriShapeExportAngularDensify Exports densified versions of non-linear segments. Generates new vertices at constant angles along those segments.
    EsriShapeExportDefaults Exports curves, Z-values, and M-values. Performs byte swapping if the current platform architecture is big-endian.
    EsriShapeExportDistanceDensify Exports densified versions of non-linear segments. Generates new vertices using a Douglas-Peucker style algorithm.
    EsriShapeExportNoCompress Does not compress the output shapefile buffer.
    EsriShapeExportNoSwap Does not perform byte swapping on the output shapefile buffer.
    EsriShapeExportStripMaterials Removes materials attributes from exported multipatch.
    EsriShapeExportStripMs Removes M values from exported shape.
    EsriShapeExportStripNormals Removes normals from exported multipatch.
    EsriShapeExportStripTextures Removes textures from exported multipatch.
    EsriShapeExportStripZs Removes Z values from exported shape.
    EsriShapeExportTrueNaNs Exports undefined double precision values as true NaNs (IEEE Non-A-Number). The default is to use large, negative values.
