ENVIDeepLearningObjectDetectionRaster::Decode

The Decode function method decompresses and base64-decodes GeoJSON code stored in the header file of an object detection raster. The GeoJSON code contains information about bounding boxes used for object detection.

This method is part of ENVI Deep Learning, which requires a separate license and installation.

Example

See the example for ENVIBoundingBoxSet::GetENVIGeoJSON.

Syntax

Result = ENVIDeepLearningObjectDetectionRaster.Decode(InputGeoJSON [, ERROR=value])

Return Value

This method returns base64-decoded and decompressed GeoJSON code.

Arguments

InputGeoJSON

Specify GeoJSON code containing bounding box information from the header file of an object detection raster.

Keywords

ERROR

Set this keyword to a named variable that will contain any error message issued during execution of this routine. If no error occurs, the ERROR variable will be set to a null string (''). If an error occurs and the routine is a function, then the function result will be undefined.

When this keyword is not set and an error occurs, ENVI returns to the caller and execution halts. In this case, the error message is contained within !ERROR_STATE and can be caught using IDL's CATCH routine. See IDL Help for more information on !ERROR_STATE and CATCH.

See the Manage Errors topic in ENVI Help for more information on error handling.
