eraseVBL() Function

 Note: This function can only be used in a Trusted Macro

Introduced in version 1.3b89
This function erases VBL shapes.

Usage

eraseVBL(shapesList)

Parameters

The shapes can be one of "Rectangle", "Circle", "Polygon" or "Cross".

For "shape":"Rectangle":

  • "x" - Abscissa in pixels. (aka: X-Coordinate)
  • "y" - Ordinate in pixels. (aks: Y-Coordinate)
  • "w" - Width in pixels.
  • "h" - Height in pixels.
  • "r" - Rotation on centre axis in degrees, clockwise.
  • "fill" - If 1 fills rectangle, otherwise creates empty shape. Optional.
  • "thickness" - Line thickness from 2 to n pixels. Lower than 2 or empty defaults to 2. Even numbers only (odd numbers get rounded down by one). Can't be bigger than width or height. Optional.
  • "scale" - If provided number not 0, will scale rectangle by x, ie scale: 2 is double, scale: 0.5 is half. Optional.
Example:
{"shape":"rectangle","x":1743,"y":2198,"w":100,"h":100,"r":45,"fill":1,"thickness":1,"scale":0}

For "shape":"Circle":

  • "x" - Abscissa in pixels.
  • "y" - Ordinate in pixels.
  • "radius" - In pixels.
  • "fill" - If 1 fills circle, otherwise creates empty shape. Optional.
  • "thickness" - Line thickness from 2 to n pixels. Lower than 2 or empty defaults to 2. Even numbers only (odd numbers get rounded down by one). Optional.
  • "sides" - Specifies how many sides the polygon will have to approximate a circle, from 3 to 100.
Example:
{"shape":"circle", "X":50, "Y":100, "radius":200, "sides":12, "thickness":3, "fill":0}

For "shape":"Polygon":

  • "r" - Rotation on centre axis in degrees, clockwise.
  • "thickness" - Line thickness from 2 to n pixels. Lower than 2 or empty defaults to 2. Even numbers only (odd numbers get rounded down by one). Optional.
  • "close" - If 1 then it will close the polygon otherwise it will leave it open. Optional.
  • "fill" - If 1 and "close" is set too fills polygon, otherwise creates empty shape. Optional.
  • "points" - JSON Array of 2 or more "x", "y" coordinates.
Example:
{"shape":"polygon","r":0,"fill":1,"close":1,"thickness":10,"points":[{"x":1993,"y":1998},{"x":2043,"y":1998},{"x":1993,"y":2148}]}

For "shape":"Cross":

  • "x" - Abscissa in pixels.
  • "y" - Ordinate in pixels.
  • "w" - Width in pixels.
  • "h" - Height in pixels.
  • "r" - Rotation on centre axis in degrees, clockwise.
  • "thickness" - Line thickness from 2 to n pixels. Lower than 2 or empty defaults to 2. Even numbers only (odd numbers get rounded down by one). Can't be bigger than width or height. Optional.
  • "scale" - If provided number not 0, will scale cross by x, ie scale: 2 is double, scale: 0.5 is half. Optional.
Example:
{"shape":"cross","x":1593,"y":2198,"w":50,"h":50,"r":22,"thickness":5,"scale":0.75}

Example

This example doesn't really do anything.
[h: exampleVariable = "a,b,c"]
[r: exampleFunction(exampleVariable, reverse)]

Returns:

c,b,a
