VectorRecordsToROI Task
This task creates a single region of interest (ROI) from all geometry records in a vector.
Example
; Start the application
e = ENVI()
; Open an input file
File = Filepath('qb_boulder_msi_vectors.shp', Subdir=['data'], $
Root_Dir=e.Root_Dir)
Vector = e.OpenVector(File)
; Get the task from the catalog of ENVITasks
Task = ENVITask('VectorRecordsToROI')
; Define inputs
Task.INPUT_VECTOR = Vector
; Run the task
Task.Execute
; Display the result
DisplayFile = Filepath('qb_boulder_msi', Subdir=['data'], $
Root_Dir=e.Root_Dir)
Raster = e.OpenRaster(DisplayFile)
View = e.GetView()
Layer = View.CreateLayer(Raster)
VisRoi = Layer.AddRoi(Task.OUTPUT_ROI)
Syntax
Result = ENVITask('VectorRecordsToROI')
Input properties (Set, Get): INPUT_VECTOR, OUTPUT_ROI_URI
Output properties (Get only): OUTPUT_ROI
Properties marked as "Set" are those that you can set to specific values. You can also retrieve their current values any time. Properties marked as "Get" are those whose values you can retrieve but not set.
