Function Documentation

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

Definition at line 204 of file io_tiff_all.c.

Here is the call graph for this function:

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:
$ 0 $ if OK, $\neq 0 $ if an error occured

Here is the caller graph for this function:

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:
$ 0 $ if OK, $\neq 0 $ if an error occured
