Example

Remarks

Some file formats can contain comments, and some cannot, and each file format has its own set of comment types. When you save a file, the comments in the Leadtools.RasterImage object can be saved in the file. The index into the array (specified using a constant) determines the type of comment.

You can use RasterCodecs.CommentsSupported to check if a certain file format supports tags.

To read all the comments stored in a file, use RasterCodecs.ReadComments.

Requirements

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