Loads a grayscale fingerprint image from a picture file.
| Prerequisites | The capture module must have been previously initialized. Picture file must be in one of the supported formats, as defined in the section. Image capture must have been previously started on the "File" sensor. |
| Return | On success, GR_OK is returned. On failure, the appropriate error code is returned. |
| [in] fileName |
The complete path and filename of the picture file to load. |
| [in] res |
Image resolution in DPI. |
On success, an image event is fired for the "File" sensor.
