dVerticalSymmetry (Function)

In french: dSymétrieVerticale

Flips an image with respect to a vertical axis (symmetry with respect to a vertical axis). This image can correspond to:

an Image control,
a variable of type Image.
a variable of type WDPic (on the background layer),
a variable of type picLayer.

Caution: In Linux, this function requires a specific configuration. For more details, see Drawing in WINDEV, WEBDEV and WINDEV Mobile.

Example

// Symétrie verticale du champ IMG_Image1
MonRésultat is boolean
MonRésultat = dVerticalSymmetry(IMG_Image1)
IF MonRésultat = False THEN Error("L'opération a échoué")

Syntax

<Result> = dVerticalSymmetry(<Image>)

<Result>: Boolean

True if symmetry has been achieved,
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.
the name of a variable of type WDPic. Only the background layer will be handled.
the name of a variable of type picLayer.
The symmetry is performed in relation to the median vertical axis of the control or of the image. The image is directly modified.

Remarks

End of drawing

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