<Image>.Rotation (Function)

In french: <Image>.Rotation

Rotates an Image control.

Caution: A specific configuration is required to use this function in Linux. For more details, see The drawings.

Example

// Rotate the IMG_Image1 control by 45 degrees
Result1 is boolean
Result1 = IMG_Image1.Rotation(45)
IF Result1 = False THEN Error("The operation failed")

Syntax

Performing a simple rotation Hide the details

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

<Result>: Boolean

True if the rotation was performed,
False otherwise.

<Image control>: Control name

Name of the Image control 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.
drNoEnlarging The image is flipped but not enlarged: the image may be truncated.
Constant used by default for the Image controls.

This parameter is not available.
New in version 28
This parameter is now available.

Performing a rotation while modifying the center of rotation Hide the details

<Result> = <Image control>.Rotation(<Rotation angle> , <X rotation center> , <Y rotation center> [, <Options>])

<Result>: Boolean

True if the rotation was performed,
False otherwise.

<Image control>: Control name

Name of the Image control to be used.

<Rotation angle>: Real

Rotation angle (in degrees).

<X rotation center>: Integer

X-coordinate (in pixels) of the new rotation center.

<Y rotation center>: Integer

Y-coordinate (in pixels) of the new rotation center.

<Options>: Integer constant

Rotation options:
drDefault Enlarge the image (if necessary) so that it corresponds to the dimensions of rotated image.
drNoEnlarging The image is flipped but not enlarged
Constant used by default for the Image controls.

This parameter is not available.
New in version 28
This parameter is now available.

Remarks

End of drawing

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