Function Documentation

void cleanup	(	int	status,
		const char *	fmt,
			...
	)

Frees all allocated memory.

Parameters:

	status	Exit-code for program termination.
	fmt	String to output before termination.

int main	(	int	argc,
		char **	argv
	)

The main-function.

Parameters:

	argc	Argument count.
	argv	Argument strings.

Returns:

Returns 0 on success.

void transform_channel	(	float *	img_data,
		int	pitch,
		int	dwt_levels,
		int	ezw_passes,
		int	ch_num
	)

Wavelet-transform one channel of an RGB image.

Parameters:

	img_data	The input-data.
	pitch	The input-data's pitch.
	dwt_levels	Determines, how many stages the dwt-filter has.
	ezw_passes	Determines, how many EZW-passes are to be performed on the input-data.
	ch_num	Identifier for the current channel (the R, G or B channel).
