PicRotation (Function)

In french: PicRotation

Rotates a WDPic image. All image layers rotate.

Remark: To rotate one single layer, use dRotation.

Example

// 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
