圖形介面軟體 Graphics: Nucleus GRAFIX

功能介紹 Features

Nucleus GRAFIX contains three valuable parts: Windowing Toolkit, Rendering Services and a Device Driver. The Windowing Toolkit provides a high-level interface, so you can build your GUI. This might include drawing a window, creating a pull-down menu or other common features. The Rendering Services provide the facilities necessary for the Windowing Toolkit to do its work. They provide the ability to draw lines, boxes, characters and symbols, fill in polygons, control the palette and include several other useful tools for preparing a complete presentation.

The device driver provides an interface to the hardware responsible for the drawing.

Nucleus GRAFIX Software Layers and Components

The main features of Nucleus GRAFIX are:

• Full source code provided and no royalty fees.
• Windowing Toolkit has APIs for building GUI (Graphical User Interface) and the Rendering Services package provides fundamental drawing capabilities.
• Device Driver supports the input (Mouse, Keyboard, Touch Panel) and output (VGA, LCD) devices.
• DIP and BMP file formats are supported.
• A font conversion utility for MetaGraphics fonts.
• Highly modularized and portable architecture.
• Combined with Microsoft Visual Studio, one can create a GUI.

Windowing Toolkit

The Windowing Toolkit (WT) provides a set of APIs so you can build your own embedded GUI. Because of the diversity of embedded systems, the interface could vary from a single window or pull down menu to a very complex set of interacting events with numerous windows, controls, fonts and menus. WT provides the flexibility to handle these various situations to create a comprehensive interface that suits your application. The WT provides all the necessary components needed in building a GUI and provides a complete set of functionality that works together to provide a comprehensive windowing system. The Nucleus GRAFIX Windowing Toolkit integration with Microsoft Developer Studio facilitates the creation of your GUI layout. This integration gives you an environment with access to Visual Studio to design your panels using Microsoft Visual StudioTM to produce a resource script. The "RC" script contains all the components you need to build a GUI for your target. The "RC" file is read and converted to an H source file that can be compiled and linked with your Nucleus GRAFIX application and then executed on your target.

Rendering Services

Because differing levels of application functionality require different levels of graphics capabilities, not every product design requires the same level of graphics functionality in a user interface. Some devices only require functionality that focuses on drawing primitives such as lines, graphs and text. Nucleus GRAFIX Rendering Services package provides this level of service. Products like industrial controllers, medical devices and instrumentation devices need some kind of display functionality, usually with some type of user input device. Nucleus GRAFIX Rendering Services provides the capabilities to draw lines, circles and text without the overhead associated with high-level GUI packages. Nucleus GRAFIX Rendering Services package has a user-friendly, easy-to-learn, intuitive interface for building your application. The package is designed to be extremely portable and is supported across a wide variety of processors. The API is designed to minimize the learning curve and is structured in an easy-to-use and easy-to-follow manner. Support for text manipulation, including UNICODE, is included in Nucleus GRAFIX Rendering Services, which is important in the global market and the deployment of devices in other countries.

Unicode support

With the expanding global market, there is a need to understand multinational character sets. Because of this need, support for two-byte character sets and UNICODE support is built into the Nucleus GRAFIX package.

Device Drivers

Display Devices (Output Devices)

Nucleus GRAFIX allows support for multiple output devices including support for LCD, VGA and SVGA at multiple resolutions. With the growing LCD market, it is clear that the introduction of new controllers and devices is not going to slow down. Therefore, it is critical that a solution exists that can be easily migrated to new devices as well as custom hardware devices with minimal effort. The modular design of the driver allows for the quick adaptation to new controllers. Since the driver code base is designed for portability, supporting new controllers is very easy and requires only a few changes.

We are constantly doing porting for new controllers, please contact your local sales representative for availability.

Input Devices

Interaction with the user is a requirement for graphical designs and Nucleus GRAFIX offers a wide variety of options for input. Nucleus GRAFIX supports multiple input mechanisms including a keyboard, mouse and touch panel devices. Support is built into the package to facilitate the easy introduction of new devices.

We are constantly doing porting for new controllers, please contact your local sales representative for availability.
