FlipCplImage()

bool FlipCplImage	(	cpl_image *	image,
		int	angle
	)

Flip an image on mirror line.

Parameters

image	CPL image object
angle	Flip the image, using theta as multiples of (PI/4) 0: flip around the horizontal 1: flip around y=x 2: flip around the vertical 3: flip around y=-x

Returns

bool indicating success of flipping

RotateCplImage()

bool RotateCplImage	(	cpl_image *	image,
		int	rotate
	)

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

Parameters

image	CPL image object
rotate	Rotate the image by multiples of 90 deg -3: 270 degrees counterclockwise -2: 180 degrees counterclockwise -1: 90 degrees counterclockwise 0: do not turn +1: 90 degrees clockwise +2: 180 degrees clockwise +3: 270 degrees clockwise

Returns

bool indicating success of rotation

ThresholdCplImage()

bool ThresholdCplImage	(	cpl_image *	image,
		double	lower_bound,
		double	higher_bound,
		double	low_cut_value,
		double	high_cut_value
	)

Threshold an image to an interval.

Parameters

image	CPL image object
lower_bound	lower pixel value threshold
higher_bound	higher pixel value threshold
low_cut_value	value to assign to pixels below lower threshold
high_cut_value	value to assign to pixels above higher threshold

Returns

bool indicating success of cutting
