Description

Interface Summary

ICallBackNotifier	This interface adds the callback ability to the existing IUpdateNotifer interface, any listener who want to perform a callback must implement this instead of the original IUpdateNotifer.
IDeviceRenderer	Combines the primitive rendering notifications provided in the primitive and other convenience methods needed by a device renderer.
IDisplayServer	Provides generic services to a device renderer for computing metrics and centralized creation of device specific resources.
IImageMapEmitter	This interface defines the capability for implementors to provide an html image map string.
IPrimitiveRenderer	Provides low level primitive rendering notifications that are interpreted by a device renderer.
IStructureDefinitionListener	Notifies a listener of group change events associated with a structure being rendered.
ITextMetrics	Provides a layer of abstraction for text metrics retrieval via display server dependent implementations.
ITextRenderer	Provides convenience methods for rendering rotated text with configurable attributes on a graphics context.
IUpdateNotifier	Defines methods that allow model updating via a device event handler used in conjunction with a device renderer.

Package org.eclipse.birt.chart.device Description

Provides interfaces and no-op adapters that define services provided by the device renderer and an associated display server. A device renderer is responsible for rendering a chart on a device-specific context (e.g. an image into a JPEG file). A display server is responsible for providing device-specific metrics needed to build charts and compute preferred sizes of the various chart components.
