The Leadtools.RasterImageFormat to check
Checks whether the given file format supports TIFF Geo key tags

Syntax

Visual Basic (Declaration) 
Public Shared Function GeoKeysSupported( _
   ByVal format As RasterImageFormat _
) As Boolean
Visual Basic (Usage)Copy Code
Dim format As RasterImageFormat
Dim value As Boolean
 
value = RasterCodecs.GeoKeysSupported(format)
C# 
public static bool GeoKeysSupported( 
   RasterImageFormat format
)
C++/CLI 
public:
static bool GeoKeysSupported( 
   RasterImageFormat format
) 

Parameters

format
The Leadtools.RasterImageFormat to check

Return Value

true if the format supports TIFF Geo key tags; otherwise it is false.

Example

For an example, refer to RasterCodecs.ReadTags.

Remarks

This is a helper method that can be used to detect if a certain raster file format supports TIFF Geo key tags. For example, ReadGeoKey(String,Int32,Int32), RasterCodecs.ReadGeoKeys and EnumGeoKeys(String,Int32) can be used to read the geo keys stored in a file. If the file format supports geo keys, such as TIFF, then these methods will successfully return the geo key tags stored.

However, if the format does not support geo key tags, such as BMP, an exception will be thrown by the RasterCodecs objects. You can use RasterCodecs.GeoKeysSupported to check if the file supports geo keys and only call the read methods if the return value is true.

Note that the RasterCodecs option uses this method internally to check if the file supports geo keys when the CodecsLoadOptions.GeoKeys is set to true and only read the file geo keys if the file format supports them.

Requirements

Target Platforms: Silverlight, Windows XP, Windows Server 2003 family, Windows Server 2008 family, Windows Vista, Windows 7, MAC OS/X (Intel Only)
