Write TIFF image to file (in dipIO)
#include "dipio_tiff.h"
dip_Error ImageWriteTIFF ( image, filename, photometric, physDims, compression )
This function writes the image to a TIFF file, overwriting any other file with the same name. photometric can set to let the function know how to write the TIFF image (supported colour spaces are RGB, CIE Lab and CMYK).
If photometric is not DIPIO_PHM_GRAYVALUE, a 3D image is expected, in which the different planes are stored along the 3rd dimension.
physDims gives physical dimensions of the image, which will be used to set the dots per inch property of the TIFF file. It can be set to 0 for default values (300 dpi). If the physDims->dimensionUnits is not given, meters are assumed.
| Data type | Name | Description |
| dip_Image | image | Output image |
| dip_String | filename | File name |
| dipio_PhotometricInterpretation | photometric | Photometric interpretation |
| dip_PhysicalDimensions | physDims | Physical dimensions structure. See PhysicalDimensionsNew |
| dipio_Compression | compression | Compression method and level. See Compression methods for image files |
The enumerator dipio_PhotometricInterpretation contains the following constants:
| Name | Description |
| DIPIO_PHM_GREYVALUE | No colour information present; it's a grey-value image. |
| DIPIO_PHM_RGB | RGB image (the first three planes are red, green and blue) |
| DIPIO_PHM_RGB_NONLINEAR | Non-linear R'G'B' image (RGB channels to the power of 0.4) |
| DIPIO_PHM_CMY | CMY image (the first three planes are cyan, magenta and yellow) |
| DIPIO_PHM_CMYK | CMYK image (the first four planes are cyan, magenta, yellow and black) |
| DIPIO_PHM_CIELUV | CIE L*u'v' image (the first three planes are luminosity, u* and v*) |
| DIPIO_PHM_CIELAB | CIE L*a*b* image (the first three planes are luminosity, a* and b*) |
| DIPIO_PHM_CIEXYZ | CIE XYZ (the first three planes are X, Y and Z) |
| DIPIO_PHM_CIEYXY | CIE Yxy (the first three planes are Y, x and y) |
| DIPIO_PHM_HCV | HCV image (the first three planes are hue, chroma and value) |
| DIPIO_PHM_HSV | HSV image (the first three planes are hue, saturation and value) |
| DIPIO_PHM_DEFAULT | Same as DIPIO_PHM_GREYVALUE |
| DIPIO_PHM_GENERIC | Anything can be coded in the channels; the same as DIPIO_PHM_CMYK |
Most file formats support only some of these.
