数字图像处理

DEM渲染显示，用OpenGL实现渲染和漫游(DEM display rendering, implemented with OpenGL rendering and roaming )

本项目是以虚拟机ubuntu14.04为软件环境，以开发板s5pv210（内核版本为Cortex-A8）为硬件平台，直接基于linux API实现对bmp、jpg、png三种图片格式进行解码显示，能够实现不同分辨率图片的显示，并且实现点击触摸屏翻页以及图片的放大缩小功能。

说明：  窗体自适应，统计原始窗体的位置和大小；缩放后Resize通过计算主窗体的大小，计算出长宽伸缩比例，然后再计算出来内部控件的起始点和长宽，过程通过递归完成，简单易行！(The window adapts itself and counts the position and size of the original window; after scaling, resize calculates the length and width scaling ratio by calculating the size of the main window, and then calculates the starting point and length and width of the internal control. The process is completed by recursion, which is simple and easy!)

应用背景主要用于查看C语言基本数组类型在KEIL编译器中所占的字节大小关键技术基于STM32的 C语言编辑，串口的配置方法，printf输出函数的使用，以及keil软件的调试
