Introduced in version 1.3b90
Gets the Vision Blocking Layer (VBL) shapes for the area specified in the shape parameter.

Usage

getVBL(shape)
getVBL(shape,format)

This function retrieves the VBL found in the given shape(s).

Parameters

  • shape - A JSON object, or an array of JSON objects, as described in drawVBL(). If an array, gets all the VBL within all provided shapes, otherwise just the VBL in the single provided shape.
  • format - OPTIONAL Boolean. Returns a JSON object if false(0), or a JSON array of coordinates if true(1). In either case, the returned shape covers the VBL found in the area. Defaults to false(0)

Examples

[h:rectangle = '{"shape":"rectangle","x":50,"y":50,"w":100,"h":200,"r":45,"fill":1,"thickness":1,"scale":0}']
[r:vblData   = getVBL(rectangle , 0)]
