ConvertMapToPixelCoordinates Task

This task converts map (northings/eastings) coordinates to pixel coordinates.

Example

; Start the application

e = ENVI(/HEADLESS)

; Open an input file

File = Filepath('qb_boulder_msi', Subdir=['data'], $

  Root_Dir=e.Root_Dir)

Raster = e.OpenRaster(File)

; Get the task from the catalog of ENVITasks

Task=ENVITask('ConvertMapToPixelCoordinates')

; Define inputs

Task.INPUT_COORDINATE = [482399.0584,4427505.0643]

Task.SPATIAL_REFERENCE = Raster.SPATIALREF

; Run the task

Task.Execute

; Get the output coordinates

Print, Task.OUTPUT_COORDINATE

Result:

761.37946       526.21429

Syntax

Result = ENVITask('ConvertMapToPixelCoordinates')

Input properties (Set, Get): INPUT_COORDINATE, SPATIAL_REFERENCE

Output properties (Get only): OUTPUT_COORDINATE

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.
