GeoKeysSupported Method
Summary
Checks whether the given file format supports TIFF GeoKey tags
Syntax
public static bool GeoKeysSupported(Leadtools.RasterImageFormat format)
Public Shared Function GeoKeysSupported( _ByVal format As Leadtools.RasterImageFormat _) As Boolean
public static bool GeoKeysSupported(Leadtools.RasterImageFormat format)
+ (BOOL)geoKeysSupported:(LTRasterImageFormat)format public static boolean geoKeysSupported(RasterImageFormat format) function Leadtools.Codecs.RasterCodecs.GeoKeysSupported(format)
public:static bool GeoKeysSupported(Leadtools.RasterImageFormat format)
Parameters
format
The RasterImageFormat to check
Return Value
true if the format supports TIFF GeoKey tags; otherwise it is false.
Remarks
This is a helper method that can be used to detect if a certain raster file format supports TIFF GeoKey tags. For example, ReadGeoKey, ReadGeoKeys and EnumGeoKeys can be used to read the GeoKeys stored in a file. If the file format supports GeoKeys, such as TIFF, then these methods will successfully return the GeoKey tags stored.
However, if the format does not support GeoKey tags, such as BMP, an exception will be thrown by the RasterCodecs objects. You can use GeoKeysSupported to determine whether the file supports GeoKeys and only call the read methods if the return value is true.
Note that the RasterCodecs option uses this method internally to determine whether the file supports GeoKeys when the CodecsLoadOptions.GeoKeys is set to true and only read the file GeoKeys if the file format supports them.
Example
For an example, refer to ReadTags.
