Public Methods

Method Description
emit_message ( int msg_level ) : void

Conditionally emit a trace or warning message.

The main reason for overriding this method would be to abort on warnings. This method calls output_message for message showing.
An application might override this method if it wanted to abort on warnings or change the policy about which messages to display.

error_exit ( ) : void

Receives control for a fatal error.

This method calls output_message and then throws an exception.

format_message ( ) : string

Constructs a readable error message string.

This method is called by output_message. Few applications should need to override this method. One possible reason for doing so is to implement dynamic switching of error message language.

jpeg_error_mgr ( ) : System

Initializes a new instance of the jpeg_error_mgr class.
output_message ( ) : void

Actual output of any JPEG message.

Override this to send messages somewhere other than Console. Note that this method does not know how to generate a message, only where to send it. For extending a generation of messages see format_message.

reset_error_mgr ( ) : void

Resets error manager to initial state.

This is called during compression startup to reset trace/error processing to default state. An application might possibly want to override this method if it has additional error processing state.

Protected Methods

Method Description
GetMessageText ( int code ) : string

Gets the actual message texts.

It may be useful for an application to add its own message texts that are handled by the same mechanism. You can override GetMessageText for this purpose. If you number the addon messages beginning at 1000 or so, you won't have to worry about conflicts with the library's built-in messages.
