Function Documentation

SubarrayLineDouble()

std::vector<double> SubarrayLineDouble	(	cpl_image *	image,
		int	x0,
		int	y0,
		const int	x1,
		const int	y1
	)

Returns a double subarray of pixel values from a cpl_image along a line defined by start and end point (x and y image coordinates)

SubarrayLineInt() [1/2]

std::vector<int> SubarrayLineInt	(	cpl_image *	image,
		int	x0,
		int	y0,
		int	x1,
		int	y1
	)

Returns an integer subarray of pixel values from a cpl_image along a line defined by start and end point (x and y image coordinates)

SubarrayLineInt() [2/2]

std::vector<int> SubarrayLineInt	(	cpl_image *	image,
		std::tuple< int, int >	start,
		std::tuple< int, int >	end
	)

This file is part of the DDT Image Handling Library and provides functions to process CPL images.

The usage is as follows:

#include "ddt/imageProc.hpp" ... using namespace ddt; Returns an integer subarray of pixel values from a cpl_image along a line defined by start and end point (tuples of image coordinates)

SubarrayRectInt() [1/2]

std::vector<std::vector<int> > SubarrayRectInt	(	cpl_image *	image,
		int	llx,
		int	lly,
		int	urx,
		int	ury
	)

Returns an integer subarray of pixel values from a cpl_image within a rectangle defined by two corners (coordinates of lower left and upper right corners)

SubarrayRectInt() [2/2]

std::vector<std::vector<int> > SubarrayRectInt	(	cpl_image *	image,
		std::tuple< int, int >	start,
		std::tuple< int, int >	end
	)

Returns an integer subarray of pixel values from a cpl_image within a rectangle defined by two corners (tuples of image coordinates)

SubImageCircular()

cpl_image* SubImageCircular	(	cpl_image *	image,
		int	xcenter,
		int	ycenter,
		int	radius
	)

Returns a circular CPL subimage from a cpl_image. The circular area is defined by the center coordinates and the radius. The returned rectangle has all pixels lying outside the circular area added to the bad pixel map. The image has to be deleted using cpl_image_delete().

SubImageRect() [1/2]

cpl_image* SubImageRect	(	cpl_image *	image,
		int	llx,
		int	lly,
		int	urx,
		int	ury
	)

Returns a CPL subimage from a cpl_image within a rectangle defined by two corners (coordinates of lower left and upper right corners)

Returns a CPL subimage from a cpl_image within a rectangle defined by two corners (coordinates of lower left and upper right corners)

The image has to be deleted using cpl_image_delete().

SubImageRect() [2/2]

cpl_image* SubImageRect	(	cpl_image *	image,
		std::tuple< int, int >	start,
		std::tuple< int, int >	end
	)

Returns a CPL subimage from a cpl_image within a rectangle defined by two corners (tuples of image coordinates)

Returns a CPL subimage from a cpl_image within a rectangle defined by two corners (tuples of image coordinates)

The image has to be deleted using cpl_image_delete().
