<picLayer variable>.Rotation (Function)

In french: <Variable picCalque>.Rotation

Rotates an image in a variable of type picLayer.

Example

MyWDPicImage is WDPic = "Test.gif"
MyLayer is picLayer

// Rotate layer by 45 degrees
Result1 is boolean
Result1 = MyLayer.Rotation(45)
IF Result1 = False THEN Error("The operation failed")
IMG_MyDrawing = MyWDPicImage

Syntax

Performing a simple rotation Hide the details

<Result> = <picLayer image>.Rotation(<Rotation angle> [, <Options>])

<Result>: Boolean

True if the rotation was performed,
False otherwise.

<picLayer image>: picLayer variable

Name of the picLayer variable to be used.

<Rotation angle>: Real

Rotation angle (in degrees).
If the angle is positive, the image rotates clockwise.
If the angle is negative, the image rotates counterclockwise.

<Options>: Integer constant

Rotation options:
drAdapt The image is flipped and enlarged. Then, its size is reduced to correspond to the initial image size.
drDefault Enlarge the image (if necessary) so that it corresponds to the dimensions of rotated image.
Constant used by default for the picLayer variables.
drNoEnlarging The image is flipped but not enlarged: the image may be truncated.

Remarks

End of drawing

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