Example
// Symmetry of IMG_IMAGE1 with respect to a horizontal axis
MyResult is boolean
MyResult = dHorizontalSymmetry(IMG_IMAGE1)
IF MyResult = False THEN Error("The operation failed")
Syntax
<Result> = dHorizontalSymmetry(<Image>)
<Result>: Boolean
  • True if the symmetry was performed,
  • False otherwise.
<Image>: Name of Image control, Image, WDPic or picLayer variable
