TIOParams.IEN_StoreBackground

Declaration

property IEN_StoreBackground: Boolean;

Description

Specifies whether the image background (layer 0) is saved to the IEN file.
When IEN_StoreBackground = True, the background image and all other layers are saved.
When IEN_StoreBackground = False, layers 1 to LayersCount -1 are saved, and layer 0 is skipped.

Note: IEN_StoreBackground has no effect when loading, to load layers without the background layer, see the examples for LoadFromFileIEN

Default: True

Example

// Save annotations only
ImageEnView1.IO.Params.IEN_StoreBackground := False;
ImageEnView1.IO.SaveToFile( 'D:\annot.ien' );

// Load an image that has been saved with IEN_StoreBackground = False
// Load background image
ImageEnView1.IO.LoadFromFile( 'C:\image.jpg' );
// Load annotations
ImageEnView1.IO.LoadFromFile( 'D:\annot.ien' );
