Example
MyImage is Image = "Test.gif"
// Changes the hue, the lightness and the saturation
// of the image found in the IMG_Image1 control
MyImage.ModifyHSL(50,50,50)
IMG_MyDrawing = MyImage
 
Syntax
<Result> = <Image variable>.ModifyHSL(<Variation of hue> , <Variation of saturation> , <Variation of lightness> [, <Destination image>])
<Result>: Boolean
  • True if the change was performed,
  • False otherwise.
<Image variable>: Image variable
Name of the Image variable to use.
<Variation of hue>: Integer
Value included between -360 and +360. This value will be added to the current hue of each pixel to get a new hue.
<Variation of saturation>: Integer
Value included between -100 and +100. This value will be added to the current saturation of each pixel to get a new saturation.
<Variation of lightness>: Integer
Value included between -100 and +100. This value will be added to the current lightness of each pixel to get a new lightness.
<Destination image>: Name of the Image control or variable
Image where the transformed image will be drawn. This image can correspond to:
  • the name of an Image control.
  • the name of an Image variable.
If this parameter is not specified, the transformation will be performed on <Image variable>
