All Implemented Interfaces:

DisplayStrategy

public class TextStyleDisplayStrategy
extends AbstractDisplayStrategy

This DisplayStrategy implementation shows annotation elements in the transcription text by changing the style (font, color, etc) of the text. You can set this style by calling one of the many-parameter-constructors or by creating a template style that is to be used as example.

Uses NTranscriptionView.insertCopyOfStyle and NTranscriptionView.removeStyleFromChain for maintaining the styles.
