Checks whether the given file format supports Geo TIFF key tags.
#include "l_bitmap.h"
L_LTFIL_API L_BOOL L_GeoKeysSupported(nFormat)
Input file format. For valid values, refer to Files To Be Included With Your Application.
| Value | Meaning |
|---|---|
| TRUE | If the format supports geo keys. |
| FALSE | If the format does not support geo keys. |
This is a helper function that can be used to detect if a certain raster file format supports geo keys. For example, L_ReadFileGeoKey, L_ReadFileGeoKeys and L_EnumFileGeoKeys function scan be used to read the geo keys stored in a file. If the file format supports tags, such as GeoTIFF, then these methods will successfully return the geo keys stored.
However, if the format does not support geo keys, such as BMP, an error will be returned by these functions. You can use the L_GeoKeysSupported function to check if the file supports geo keys and only call the read geo keys methods if the return value is TRUE.
For general information about TIFF tags, refer to Implementing TIFF Comments and Tags.
Win32, x64, Linux.
For an example, refer to L_ReadFileTags.
