<Image variable>.Rotation (Function)

In french: <Variable Image>.Rotation

Rotates an image in an Image variable.

Example

MyImage is Image = "Test.gif"
// Turn the IMG_Image1 control round 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 was performed,
False otherwise.

<Image variable>: Image variable

Name of Image variable to use.

<Rotation angle>: Real

Rotation angle (in degrees).
If the angle is positive, the image is turned clockwise.
If the angle is negative, the image is turned anticlockwise.

<Options>: Integer

Versions 17 and later
Rotation options:
drAdapt The image is turned while it is 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 turned but it is not enlarged: the image may be truncated.
Constant used by default for the Image controls.

This parameter is not available.

End of drawing

The transformation of the image will not be displayed if <Image variable>.EndDrawing and <Image variable>.Rotation are called in the same process.
