float* read_tiff_f32	(	const char *	fname,
		size_t *	nx,
		size_t *	ny,
		size_t *	nc
	)

load the data from a TIFF image file as a float RGB or grayscale array

The array is allocated in this function call. It holds the RGB pixels as 3 contiguous arrays.

Parameters:

[in]	fname	the file name to read
[in]	nx	memory space for the image width
[in]	ny	memory space for the image height
[in]	nc	memory space for number of channels

Returns:

the data array pointer, NULL if an error occured

unsigned char* read_tiff_u8	(	const char *	fname,
		size_t *	nx,
		size_t *	ny,
		size_t *	nc
	)

load the data from a TIFF image file as a 8bit RGB or grayscale array

The array is allocated in this function call. It hold the RGB pixels as 3 contiguous arrays.

Parameters:

[in]	fname	the file name to read
[in]	nx	memory space for the image width
[in]	ny	memory space for the image height
[in]	nc	memory space for number of channels

Returns:

the data array pointer, NULL if an error occured

int write_tiff_f32	(	const char *	fname,
		const float *	data,
		size_t	nx,
		size_t	ny,
		size_t	nc
	)

save one or three contiguous float arrays into a TIFF file

Parameters:

[in]	fname	TIFF file name
[in]	data	input array of float values supposed in [0,255] 1 or 3 contiguous color channels arrays
[in]	nx	memory space for the image width
[in]	ny	memory space for the image height
[in]	nc	memory space for number of channels

Returns:

if OK, if an error occured

int write_tiff_u8	(	const char *	fname,
		const unsigned char *	data,
		size_t	nx,
		size_t	ny,
		size_t	nc
	)

save one or three unsigned char arrays into a TIFF file

Note: the conversion here is useless, but kept for code symmetry.

Parameters:

[in]	fname	TIFF file name
[in]	data	input array of unsigned char values, 1 or 3 contiguous color channels arrays
[in]	nx	memory space for the image width
[in]	ny	memory space for the image height
[in]	nc	memory space for number of channels

Returns:

if OK, if an error occured
