Parameters

format

The Leadtools.RasterImageFormat to check

Return Value

This is a helper method that can be used to detect if a certain raster file format supports markers. For example, ReadMarkers(String) can be used to read the markers stored in a file. If the file format supports markers, such as EXIF, then these methods will successfully return the markers stored.

However, if the format does not support markers, such as BMP, an exception will be thrown by the RasterCodecs objects. You can use MarkersSupported to check if the file supports markers 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 markers when the CodecsLoadOptions.Markers is set to true and only read the file marekrs if the file format supports them.
