Inverts the colors in a variable of type WDPic.
Example
MyWDPicImage is WDPic = "Test.gif"
// Inverts the colors of MyWDPicImage
Result1 is boolean
Result1 = MyWDPicImage.InvertColor()
IF Result1 = False THEN Error("The operation failed")
IMG_MyDrawing = MyWDPicImage
Syntax
<Result> = <WDPic image>.InvertColor()
<Result>: Boolean
  • True if the inversion of colors was performed,
  • False otherwise.
<WDPic image>: WDPic variable
Name of the WDPic variable to be used. Only the background layer will be handled.
Each pixel found in the image takes the opposite color from its initial color (bit-to-bit reversal). The image used is directly modified.
Remarks

If <WDPic variable>.EndDrawing and <WDPic variable>.InvertColor are called in the same process, the image changes will not be displayed.
