PicRotation (Function) In french: PicRotation Rotates a WDPic image. All image layers rotate. Remark: To rotate one single layer, use dRotation.
// Open a source image
MyWDPicImage is WDPic
MyWDPicImage.FileName = fExeDir() + ["\"] + "Source.png"
// Rotate the image
PicRotation(MyWDPicImage, 45)
// Save the result
PicSave(MyWDPicImage, fExeDir() + ["\"] + "Result.png")
Syntax
Performing a simple rotation Hide the details
<Result> = PicRotation(<WDPic image> , <Angle> [, <Options>])
<Result>: Boolean - True if the rotation was performed,
- False otherwise.
<WDPic image>: WDPic variable Name of the WDPic variable that contains the image to use. <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 constant Rotation options: | | | drAdapt | The image is flipped and enlarged. Then, its size is reduced to correspond to the initial image size. | drDefault
(default value) | 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. |
Performing a rotation while modifying the center of rotation Hide the details
<Result> = PicRotation(<WDPic image> , <Angle> , <X> , <Y> [, <Options>])
<Result>: Boolean - True if the rotation was performed,
- False otherwise.
<WDPic image>: WDPic variable Name of the WDPic variable that contains the image to use. <Angle>: Real Rotation angle (in degrees). - If the angle is positive, the image rotates clockwise.
- If the angle is negative, the image rotates counterclockwise.
<X>: Real New X-coordinate of the center of rotation. <Y>: Real New Y-coordinate of the center of rotation. <Options>: Optional Integer constant Rotation options: | | drDefault
(Default value) | Enlarge the image (if necessary) so that it corresponds to the dimensions of rotated image. | | drNoEnlarging | The image is flipped but not enlarged |
