Reverses the colors:
  • in an Image control,
  • in a variable of type Image.
  • WINDEV in a variable of type WDPic (on the background layer),
  • WINDEV in a variable of type picLayer.

Example
// Inverse les couleurs du champ IMG_Image1
Résultat1 is boolean
Résultat1 = dInvertColor(IMG_Image1)
IF Résultat1 = False THEN Error("L'opération a échoué")
Syntax
<Result> = dInvertColor(<Image>)
<Result>: Boolean
  • True if color reversal has been performed,
  • False otherwise.
<Image>: Name of the Image control, Image, WDPic or picLayer variable
Image to use. This image can correspond to:
  • the name of an Image control.
  • the name of a variable of type Image.
  • WINDEV the name of a variable of type WDPic. Only the background layer will be handled.
  • WINDEV the name of a variable of type picLayer.
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

End of drawing

If dEndDrawing and dInvertColor are called in the same process, the image changes will not be displayed.
