函数名: getfillsettings 功 能: 取得有关当前填充模式和填充颜色的信息 用 法: void far getfillsettings(struct fillsettingstype far *fillinfo); 程序例: #include #include #include #include / the names of the fill styles supported */ char *fname = { "EMPTY_FILL", "SOLID_FILL", "LINE_FILL", "LTSLASH_FILL", "SLASH_FILL", "BKSLASH_FILL", "LTBKSLASH_FILL", "HATCH_FILL", "XHATCH_FILL", "INTERLEAVE_FILL", "WIDE_DOT_FILL", "CLOSE_DOT_FILL", "USER_FILL" }; int main(void) { /* request auto detection */ int gdriver = DETECT, gmode, errorcode; struct fillsettingstype fillinfo; int midx, midy; char patstr, colstr; /* initialize graphics and local variables */ initgraph(&gdriver, &gmode, ""); /* read result of initialization */ errorcode = graphresult(); if (errorcode != grOk) /* an error occurred */ { printf("Graphics error: %s\n", grapherrormsg(errorcode)); printf("Press any key to halt:"); getch(); exit(1); /* terminate with an error code */ } midx = getmaxx() / 2; midy = getmaxy() / 2; /* get information about current fill pattern and color */ getfillsettings(&fillinfo); /* convert fill information into strings */ sprintf(patstr, "%s is the fill style.", fname[fillinfo.pattern]); sprintf(colstr, "%d is the fill color.", fillinfo.color); /* display the information */ settextjustify(CENTER_TEXT, CENTER_TEXT); outtextxy(midx, midy, patstr); outtextxy(midx, midy+2*textheight("W"), colstr); /* clean up */ getch(); closegraph(); return 0; }
