Name
rotate_imagerotate_imageRotateImagerotate_imageRotateImageRotateImage — Rotate an image about its center.
rotate_imagerotate_imageRotateImagerotate_imageRotateImageRotateImage rotates the ImageImageImageImageImageimage
counterclockwise by PhiPhiPhiPhiPhiphi degrees about its center and stores
the result in the output image ImageRotateImageRotateImageRotateImageRotateImageRotateimageRotate. The output image
has the same size as the input image. The only exception are rotations
by 90 and 270 degrees where width and height will be exchanged.
The domain of the input image is ignored, i.e., assumed to be the
full rectangle of the image. The domain of the output image is the
intersection of the transformed rectangle and the rectangle of the
ouput image.
If PhiPhiPhiPhiPhiphi is a multiple of 90 degrees, this operator is much
faster, especially than the general operator
affine_trans_imageaffine_trans_imageAffineTransImageaffine_trans_imageAffineTransImageAffineTransImage.
The effect of the parameter InterpolationInterpolationInterpolationInterpolationInterpolationinterpolation is the same as in
affine_trans_imageaffine_trans_imageAffineTransImageaffine_trans_imageAffineTransImageAffineTransImage. It is ignored for rotations by 90,
180, and 270 degrees. If it is necessary to rotate the domain, too,
the operator projective_trans_imageprojective_trans_imageProjectiveTransImageprojective_trans_imageProjectiveTransImageProjectiveTransImage has to be used.
The domain of the input image is ingnored, i.e., assumed to be the
full rectangle of the image. The domain of the output image is the
intersection of the transformed rectangle and the rectangle of the
output image.
The angle PhiPhiPhiPhiPhiphi is given in degrees, not in radians. For
rotations by 90, 180, and 270 degrees rotate_imagerotate_imageRotateImagerotate_imageRotateImageRotateImage is not
parallelized internally!
rotate_imagerotate_imageRotateImagerotate_imageRotateImageRotateImage can be executed on OpenCL devices if the input
image does not exceed the maximum size of image objects of the selected
device. Due to numerical reasons, there can be slight differences
in the output compared to the execution on the CPU.
- Supports OpenCL compute devices.
- Multithreading type: reentrant (runs in parallel with non-exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Automatically parallelized on tuple level.
- Automatically parallelized on channel level.
- Automatically parallelized on internal data level.
