摘要
随着数字信息技术和网路技术的高速发展,嵌入式系统已经广泛的参透到各行各业以及人们的日常生活中,嵌入式系统技术已经成为目前最热门的技术之一。
嵌入式系统硬件平台的核心是嵌入式微处理器,ARM处理器以其小体积、高性能、低成本、低消耗的优势成为目前应用最广泛的32位高性能嵌入式RISC处理器。在工业控制、移动通信、多媒体数字消费、手持设备等嵌入式解决方案中据着非常重要的地位。
随着嵌入式技术的成熟和发展,嵌入式设备对人机界面的要求也越来越高、友好的图形界面而为嵌入式系统的人机交互提供的丰富的图形图像信息和灵活的控制方式。本文的目标是设计和实现嵌入式终端下的画图板。论文首先介绍了Linux的优点和QT开发环境的搭建,着重分析了QT在软件开发中的编程机制,并根据嵌入式应用的特点对嵌入式终端下的画图板进行了设计需求分析、具体界面的设计和整体结构的设计。本文根据画图板的主要功能,设计并实现了画图板的相关基本功能,如:新建、打开、退出、放大、缩小、还原、旋转和拉伸等。最后运行结果符合设计要求,方案可行。

Abstract
With the development of digital information technology work technology rapid development, the embedded system has widely rated into all walks of life and people's daily life, the embedded system technology has e the most popular one.
Embedded system hardware platform is the core of the embedded microprocessor, ARM processor with its small size, high performance, low cost, low consumption of advantage to e the most widely used high performance 32 bit embedded RISC processor. In industrial control, munication, multimedia digital consumer, handheld devices and embedded solutions according to a very important position.
With the maturity and development of embedded technology, embedded devices to man-machine interface requirements are also getting higher and higher, friendly graphical interface for embedded system puter interaction with rich graphics and image information and flexible control mode. The goal of this paper is to design and Realization of embedded terminal drawing board. The paper first introduces the advantages of Linux and QT development environment to build, focuses on the analysis of QT in the development of software programming mechanism, and according to the characteristics of embedded applications on embedded terminal drawing board to design needs analysis, the specific interface design and the overall structure of the
