C Tips:显示点阵汉字的小样例
非常简陋的一段小程序,演示怎样显示点阵字库。有时间的时候再详解。
#include <stdio.h> #include <stdlib.h> struct HzkInfoStruct { int HzkSelect; int HzkSquare; char * fileName; FILE * file; int martixBytesCount; unsigned char *pMatrix; }; typedef struct HzkInfoStruct HzkInfo; void SelectHZK(HzkInfo * pHzkInfo); void LoadHzkInfo(HzkInfo * pHzkInfo); void CleanupHzkInfo(HzkInfo hzkInfo); void GetQuWh(unsigned char *chineaseWord, int * qu, int * wh); void FillMartix(HzkInfo * pHzkInfo, const int qu, const int wh); void PrintMartix(HzkInfo hzkInfo); int _tmain(int argc, _TCHAR* argv[]) { unsigned char chinease[3] = "京"; HzkInfo hzkInfo; int qu; int wh; SelectHZK(&hzkInfo); if(hzkInfo.file == NULL || hzkInfo.pMatrix == NULL) { printf("HZK loading failed.
