Stored procedures
Rotates an image in a picLayer variable.
Example
MyWDPicImage is WDPic = "Test.gif"
MyLayer is picLayer
 
// Rotate layer by 45 degrees
Result1 is boolean
Result1 = MyLayer.Rotation(45)
IF Result1 = False THEN Error("The operation failed")
IMG_MyDrawing = MyWDPicImage
Syntax

Performing a simple rotation Hide the details

<Result> = <picLayer image>.Rotation(<Rotation angle> [, <Options>])
<Result>: Boolean
  • True if the rotation was performed,
  • False otherwise.
<picLayer image>: picLayer variable
Name of the picLayer variable 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 constant
Versions 17 and later
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.
Constant used by default for the picLayer variables.
drNoEnlargingThe image is turned but it is not enlarged: the image may be truncated.

End of drawing

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