在SDL中顯示GBK點陣漢字

1、在SDL中顯示GBK點陣漢字    大家注意到?jīng)]有，RA2的中文版本使用的是GBK點陣字庫，這樣做有一個好處：不管玩家是用的簡體還是繁體都能識別顯示的文字。 GBK的意思大概是“國家標(biāo)準(zhǔn)漢字?jǐn)U展字符集”吧，記不清了。但它的確是個好東東，比GB2312、BIG5什么的強多了。因為它包括GB2312、GBK的所有字符而且還補充了很多字，另外，還包括日文、朝鮮文以及大量的符號字符。 我在UCDOS for win版本里面找到了GBK的點陣字庫（HZK12.GBK、HZK14.GBK、HZK16.GBK）。分析了一下，知道了結(jié)構(gòu)。這里是我寫的一個演示程序，程序編

2、譯需要有sdl庫。遵循“慣例”，按F4切換全屏/窗口狀態(tài)，Esc退出。程序把標(biāo)準(zhǔn)輸出和標(biāo)準(zhǔn)錯誤重定向到"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

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

8、rocessEvent( ) Uint8 *keystate; keystate = SDL_GetKeyState( NULL ); if ( ( keystateSDLK_ESCAPE ) | ( keystateSDLK_q ) ) return 0; return 1; void DrawFrame( ) char tmp256; int step = 4; / sprintf( tmp, "TotalFrame=%u", frames ); TileBlt( bg, 0, 0 ); if ( rand( ) % 400 < 2 ) jx = rand( )

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, "電子對抗顯示" ); HZ_TextOut( screen, 10, 334, 12, 0, "陳青山" ); HZ_TextOut( screen , 10, 380, 12, 0, &quo
