Syntax

Performing a simple rotation Hide the details

<Result> = dRotation(<Image> , <Rotation angle> [, <Options>])
<Result>: Boolean
  • True if the rotation was performed,
  • False otherwise.
<Image>: Name of the Image control or variable
Image to use. This image can correspond to:
  • the name of an Image control.
  • Versions 17 and later
    WINDEVWindowsLinuxUser code (UMC) the name of an Image variable.
    New in version 17
    WINDEVWindowsLinuxUser code (UMC) the name of an Image variable.
    WINDEVWindowsLinuxUser code (UMC) the name of an Image variable.
    the name of an Image variable.
The rotation is performed in relation to the center of the image. The image is directly modified.
<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
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.
Constant used by default for the Image variables.
drNoEnlargingThe image is turned but it is not enlarged: the image may be truncated.
Constant used by default for the Image controls.
