To save annotations to a file, array, or stream, first specify SaveOptions to provide specific instructions for saving the annotations.
Specifying Save Options
Prior to storing the annotations, first specify SaveOptions to provide specific saving instructions.
| C# Example |  Copy Code |
|---|---|
// save all annotation layers mysaveOptions.AllLayers = true; // as NotateXpress annotations mysaveOptions.AnnType = AnnotationType.NotateXpress; // provide some information about the annotations notateXpress1.Layers.Comments = "This file was saved today"; notateXpress1.Layers.Subject = "my annotations"; notateXpress1.Layers.Title = "One awesome annotation file"; |
|
Storing to a Disk File
Use the LayerCollection.SaveToFile method to save the layer collection to an annotation file:
| C# Example | Copy Code |
|---|---|
// store to a .nxp annotation file
notateXpress1.Layers.SaveToFile(myFileName, mysaveOptions);
|
|
 |
NXP annotations files on disk can only be read if they were originally created using SaveToFile(). If they were created using SaveToByteArray() or SaveToMemoryStream(), they cannot be read correctly from disk. |
Storing to a Byte Array
Use the LayerCollection.SaveToByteArray to save annotations to a byte array:
| C# Example | Copy Code |
|---|---|
// store to a byte array
mybytearray = notateXpress1.Layers.SaveToByteArray(mysaveOptions);
|
|
Storing to Memory Stream
Use the LayerCollection.SaveToMemoryStream to save annotations to a memory stream:
| C# Example | Copy Code |
|---|---|
// store to a byte array
mymemorystream = notateXpress1.Layers.SaveToMemoryStream(mysaveOptions);
|
|
Storing to a Layer Collection
A layer collection can also be copied to another layer collection as follows:
| C# Example | Copy Code |
|---|---|
//copy the layers from one notateXpress control to another
Notatexpress1.Layers = NotateXpress2.Layers;
|
|
