Rotates an image in a variable of type Image.

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

Example

MyImage is Image = "Test.gif"
// Rotate Image variable by 45 degrees
Result1 is boolean
Result1 = MyImage.Rotation(45)
IF Result1 = False THEN Error("The operation failed")
IMG_MyDrawing = MyImage

Syntax

Performing a simple rotation Hide the details

<Result> = <Image variable>.Rotation(<Rotation angle> [, <Options>])

<Result>: Boolean

True if the rotation has been completed,
False otherwise.

<Image variable>: Image variable

Name of the Image 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

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 Image variables.
drNoEnlarging The image is rotated but not enlarged: the image may be truncated.

Remarks

End of drawing

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