Detailed Description

Functions for image transformation (transposition, rotation).

Enumeration Type Documentation

SimdTransformType

enum SimdTransformType

Describes transform type used in function SimdTransformImage in order to describe result of transformation.

Enumerator
SimdTransformRotate0	An original image. The output image has the same size as input image.
SimdTransformRotate90	Image rotated 90 degrees counterclockwise. The output width and height are equal to the input height and widht.
SimdTransformRotate180	Image rotated 180 degrees counterclockwise. The output image has the same size as input image.
SimdTransformRotate270	Image rotated 270 degrees counterclockwise. The output width and height are equal to the input height and widht.
SimdTransformTransposeRotate0	Transposed image. The output width and height are equal to the input height and widht.
SimdTransformTransposeRotate90	Image transposed and rotated 90 degrees counterclockwise. It is equal to horizontal mirroring of image. The output image has the same size as input image.
SimdTransformTransposeRotate180	Image transposed and rotated 180 degrees counterclockwise. The output width and height are equal to the input height and widht.
SimdTransformTransposeRotate270	Image transposed and rotated 270 degrees counterclockwise. It is equal to vertical mirroring of image. The output image has the same size as input image.

Function Documentation

SimdTransformImage()

void SimdTransformImage	(	const uint8_t *	src,
		size_t	srcStride,
		size_t	width,
		size_t	height,
		size_t	pixelSize,
		SimdTransformType	transform,
		uint8_t *	dst,
		size_t	dstStride
	)

Performs transformation of input image. The type of transformation is defined by SimdTransformType enumeration.

Note

This function has a C++ wrappers: Simd::TransformImage(const View<A> & src, ::SimdTransformType transform, View<A> & dst).

Parameters

[in]	src	- a pointer to pixels data of input image.
[in]	srcStride	- a row size of input image.
[in]	width	- an input image width.
[in]	height	- an input image height.
[in]	pixelSize	- a pixel size in input and output images. It can be 1, 2, 3, 4.
[in]	transform	- a type of image transformation.
[out]	dst	- a pointer to pixels data of output image.
[in]	dstStride	- a row size of output image.

TransformSize()

Point< ptrdiff_t > TransformSize	(	const Point< ptrdiff_t > &	size,
		::SimdTransformType	transform
	)

Gets size of transformed image.

Parameters

[in]	size	- a size of input image.
[in]	transform	- a type of image transformation.

Returns

- the size of transformed image.

TransformImage()

void TransformImage	(	const View< A > &	src,
		::SimdTransformType	transform,
		View< A > &	dst
	)

Performs transformation of input image. The type of transformation is defined by SimdTransformType enumeration.

Note

This function is a C++ wrapper for function SimdTransformImage.

Parameters

[in]	src	- an input image.
[in]	transform	- a type of image transformation.
[out]	dst	- an output image.
