Detailed Description

Performs transformations like mirror and rotate on images.

Note: To speed up processing instances of this class, maintain internal memory pools to reuse memory instead of allocating new memory for each transformation. The memory is freed when the instance is destroyed.

Member Function Documentation

◆ MirrorLeftRight()

Image peak::ipl::ImageTransformer::MirrorLeftRight ( const Image & inputImage ) const

inline

Mirrors the input image in the left-right direction.

If the transformed image is a bayer-format image and the number of columns is even, the format will change. (e.g. BayerBG8 -> BayerGB8)

Parameters

[in] inputImage The handle to the created image.

Returns: A new created image containing the data of the input image mirrored in the left-right direction

Exceptions

ImageFormatNotSupportedException	inputImage has a packed pixel format
Exception	An internal error has occurred.

Since: 1.0; 1.2 Will throw ImageFormatNotSupportedException if inputImage has a packed pixel format

◆ MirrorLeftRightInPlace()

void peak::ipl::ImageTransformer::MirrorLeftRightInPlace ( Image & image ) const

inline

Mirrors the given image in the left-right direction in place i.e. it will change the input image itself.

Parameters

[in,out] image The handle to the image to mirror

Exceptions

ImageFormatNotSupportedException	image has a packed pixel format
