Example
// Turn the IMG_Image1 control round 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 Image control to use.
<Rotation angle>: Real
Rotation angle (in degrees).
  • If the angle is positive, the image rotates clockwise.
  • If the angle is negative, the image rotates anticlockwise.
<Options>: Integer
Versions 17 and later
WINDEVWindowsLinuxUser code (UMC) Rotation options:
drAdaptThe image is turned while it is enlarged. Then, its size is reduced to correspond to the initial image size.
drDefaultEnlarge the image (if necessary) so that it corresponds to the dimensions of rotated image.
drNoEnlargingThe image is turned but it is not enlarged: the image may be truncated.
Constant used by default for the Image controls.

Universal Windows 10 AppJava This parameter is not available.

Performing a rotation while modifying the rotation center 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 Image control to use.
<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
