Returns the envelope of a layer query
LONG SE_stream_calculate_layer_extent
(SE_STREAM stream,
const SE_QUERYINFO query_info,
const SE_ENVELOPE *e,
LFLOAT *minz,
LFLOAT *maxz);
| stream | The stream handle |
| query_info | A pointer to an SE_QUERYINFO structure |
| envelope | A pointer to the layer's envelope |
| minz | A pointer to the minimum Z value |
| maxz | A pointer to the maximum Z value |
SE_stream_calculate_layer_extent returns the envelope for all features within the layer that pass any SQL construct, state, or spatial constraints for the stream. If no features pass these tests, the envelope is set to SE_INVALID_ENVELOPE.
