This task creates individual ROIs from each geometry record in a vector.
Example
e = ENVI()
File = Filepath('qb_boulder_msi_vectors.shp', Subdir=['data'], $
Root_Dir=e.Root_Dir)
Vector = e.OpenVector(File)
Task = ENVITask('VectorRecordsToSeparateROI')
Task.INPUT_VECTOR = Vector
Task.Execute
File = Filepath('qb_boulder_msi', ROOT_DIR=e.Root_Dir, $
SUBDIRECTORY=['data'])
Raster = e.OpenRaster(File)
View = e.GetView()
Layer = View.CreateLayer(Raster)
File = Task.OUTPUT_ROI_URI
rois = e.OpenRoi(File)
roiLayers = !NULL
FOREACH roi, rois DO $
roiLayers = [roiLayers, Layer.AddRoi(roi)]
Syntax
Result = ENVITask('VectorRecordsToSeparateROI')
Input parameters (Set, Get): INPUT_VECTOR, OUTPUT_ROI_URI
Output parameters (Get only): OUTPUT_ROI
Parameters marked as "Set" are those that you can set to specific values. You can also retrieve their current values any time. Parameters marked as "Get" are those whose values you can retrieve but not set.
Input Parameters
INPUT_VECTOR (required)
Specify an input ENVIVector that contains the geometry records.
OUTPUT_ROI_URI (optional)
Specify a string with the fully qualified path and filename for OUTPUT_ROI.
Output Parameters
OUTPUT_ROI
This is a reference to the output ROI.
