Function Documentation

int image_regression_test	(	const char *	imagefile,
		const char *	baseline,
		double	intensity_tolerance = 2.0,
		unsigned int	max_number_of_differences = 0,
		unsigned int	tolerance_radius = 0,
		int	report = 0
	)

Compare output image to baseline image.

This function compares a given image to a baseline image and returns a regression test result depending on how well the output image matches the baseline image given the provided tolerance arguments.

Parameters:

[in]	imagefile	Output image file of test run.
[in]	baseline	Baseline image file.
[in]	intensity_tolerance	Maximum tolerable intensity difference.
[in]	max_number_of_differences	Maximum number of differing pixels.
[in]	tolerance_radius	Tolerance radius.
[in]	report	Level of test report to generate. If zero, no report is generated. If greater than zero, a report is generated. Similar to the verbosity of a program, is this parameter used to set the verbosity of the report. Most implementations yet only either generate a (full) report or none.

void testdriversetup	(	int *	argc,
		char **	argv[]
	)

Parse command-line arguments and initialize test driver.

Parameters:

[in]	argc	Number of arguments.
[in]	argv	Command-line arguments.
