Rotates an Image control.
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
Reports and QueriesWindows Rotation options:
drAdaptThe image is flipped and 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 flipped but not enlarged: the image may be truncated.
Constant used by default for the Image controls.

Reports and QueriesWindows

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:
drDefaultEnlarge the image (if necessary) so that it corresponds to the dimensions of rotated image.
drNoEnlargingThe image is flipped but not enlarged
Constant used by default for the Image controls.
