Allocate an Image File Information structure (in dipIO)
dip_Error dipio_ImageFileInformationNew ( newImInfo, name, filetype, datatype, dims, resources )
Allocates a dipio_ImageFileInformation structure. It must be freed through ImageFileInformationFree, unless a resources parameter is given, in which case it will be freed automatically when freeing the resources. This structure is usually allocated by ImageFileGetInfo.
This function will fill out some of the values in the structure with the values given on the command line. All of these can be 0.
| Data type | Name | Description |
| dipio_ImageFileInformation * | newImInfo | Output structure |
| dip_String | name | Initial value for name |
| dip_String | filetype | Initial value for filetype |
| dip_DataType | datatype | Initial value for datatype |
| dip_IntegerArray | dims | Initial value for dimensions |
| dip_Resources | resources | Resources tracking structure. See ResourcesNew |
The structure dipio_ImageFileInformation contains the following elements:
| Data type | Name | Description |
| dip_String | name | File name |
| dip_String | filetype | File format string |
| dip_DataType | datatype | Data type of image |
| dip_int | sigbits | Significant bits |
| dip_IntegerArray | dimensions | Dimensions of image |
| dipio_PhotometricInterpretation | photometric | Color space |
| dip_PhysicalDimensions | physDims | Physical dimensions structure. See PhysicalDimensionsNew |
| dip_int | numberOfImages | Number of images in a TIFF file. If filetype is not "TIFF", this number is not set |
| dip_StringArray | history | History tags |
| dip_Resources | resources | Resource tracking; all elements within this structure are tracked here |
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.
