图形颜色量化和压缩源代码，算法比较稳定。

README for Picturebrowser ========================= The modified files are included as listed in the final report: -alt_ypes.h : header file for io.h -nxview.c: modified this existing, to time the running time of the display -picturebrowser.c: file which handles the logic of buttoons and the driver (button) -hardware (folder): find the project inside and install on the board -jddctmgr.c : modified manager -jdidcint.c: hardware assisted idct transform -Makefile: to compile picturebrowser (you will have to include in romfs to run our project) -io.h -zImage Running our picture viewer: -------------------------- open the project (in hardware folder) with quartus and in programmer install on the board. In the terminal: $ nio2-download -g zImage and the start nios2-terminal $ nios2-terminal at Boot, it detects the USB and run ./pictureviewer Navigate through buttons...enjoy it with moderation:) -README for Picturebrowser ====

自己编制的一个对图像进行翻转操作的程序，基于opencv-The preparation of their own image of a flip operation procedures, based on the opencv

画图程序，可以话直线，矩形，圆，椭圆和多边形-Paint program, you can, then straight, rectangular, round, oval and polygon

用c语言实现线的绘制，可重复绘制，也可以设置参数对线的颜色等属性进行修改,这是最简单的c实现，其中的BGI必须先初始化，否则程序会报错-Using c language implementation line drawing, repeatable draw, you can also set the parameters on-line to modify the color and other attributes, it is the simplest c implementation, of which BGI must be initialized, otherwise program will complain
