在SDL中显示GBK点阵汉字

1、在SDL中显示GBK点阵汉字    大家注意到没有，RA2的中文版本使用的是GBK点阵字库，这样做有一个好处：不管玩家是用的简体还是繁体都能识别显示的文字。 GBK的意思大概是“国家标准汉字扩展字符集”吧，记不清了。但它的确是个好东东，比GB2312、BIG5什么的强多了。因为它包括GB2312、GBK的所有字符而且还补充了很多字，另外，还包括日文、朝鲜文以及大量的符号字符。 我在UCDOS for win版本里面找到了GBK的点阵字库（HZK12.GBK、HZK14.GBK、HZK16.GBK）。分析了一下，知道了结构。这里是我写的一个演示程序，程序编

2、译需要有sdl库。遵循“惯例”，按F4切换全屏/窗口状态，Esc退出。程序把标准输出和标准错误重定向到"stdout.txt"和"stderr.txt"中。 #include time.h> #include stdio.h> #include stdlib.h> #include string.h>#include "SDL.h" #include "SDL_image.h" /- #define STDOUT_FILE "stdout.txt" #define STD

3、ERR_FILE "stderr.txt" SDL_Surface *screen; Uint32 fps; Uint32 AppStartTime = 0; Uint32 frame_count = 0; static Uint32 frames; SDL_Event event; SDL_Surface * SetMode( int Width, int Height, int BPP, int Flags ); SDL_Surface * LoadBMP( char * filename ); void MainLoops( int ( * EventFunc)( )

6、eString256; time_t timer; struct tm *tblock; HZ_Init(); frames = 0; timer = time(NULL); tblock = localtime(&timer); strftime( TimeString, 256, "Time=%Z: %Y-%m-%d %a %H:%M:%S", tblock ); printf( "%sn", TimeString ); SetMode( Width, Height, bpp, SDL_SWSURFACE|ScreenMode ); SDL_

7、ShowCursor(0); SDL_WM_SetCaption( "demo", "demo" ); bg = IMG_Load( "2k_bg.jpg" ); ix=iy=0; jx=jy= Height>>1; srand( (Uint32)timer ); MainLoops( ProcessEvent, DrawFrame, 0 ); printf( "ScreenMode=%d*%d*%dnFPS=%u", Width, Height, bpp, fps ); return 0; int P

9、% ( Width - 10 ); jy = rand( ) % ( Height - 10 ); sprintf( tmp, "FPS=%d", fps ); HZ_TextOut( screen, 10, 300, 12, 0, "正面面板"); HZ_TextOut( screen, 10, 318, 12, 0, "电子对抗显示" ); HZ_TextOut( screen, 10, 334, 12, 0, "陈青山" ); HZ_TextOut( screen , 10, 380, 12, 0, &quo
