Comments # get (RasterImage)
A collection of RasterCommentMetadata used when reading and writing certain file formats (including GIF).
Several formats allow you to store non-image data such as comments, tags, and markers.
You can manipulate the comments of an image by adding/removing RasterCommentMetadata objects to this collection.
By setting the CodecsSaveOptions.Comments property to true before calling RasterCodecs.Save, you can save the comments in this collection when the image is saved into a file.
By setting the CodecsLoadOptions.Markers property to true before calling RasterCodecs.Load, you can load all the markers (if any) into this collection when an image is loaded from a file.
You can use the RasterCodecs.WriteMarkers method to save the markers directly to an existing file.
For more information, refer to Non Image Data and Types of File Comments.
