settextjustify為圖形函式設定文本的對齊方式
基本介紹
- 中文名：settextjustify
- 功能：為圖形函式設定文本的對齊方式
- 作用對象：圖形函式
- 性質：函式名
簡介,程式例,
簡介
用 法: void far settextjustify(int horiz, int vert);
horiz將決定（x,y）點水平位置相對輸出位置如何確定，
vert參數決定（x,y）點的垂直位置相對輸出位置如何確定。
程式例
#include <graphics.h>#include <stdlib.h>#include <stdio.h>#include <conio.h>/* function prototype */void xat(int x, int y);/* horizontal text justification settings */char *hjust[] = { "LEFT_TEXT","CENTER_TEXT","RIGHT_TEXT"};/* vertical text justification settings */char *vjust[] = { "LEFT_TEXT","CENTER_TEXT","RIGHT_TEXT"};int main(void){/* request auto detection */ int gdriver = DETECT, gmode, errorcode; int midx, midy, hj, vj; char msg[80];/* 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;/* loop through text justifications */for (hj=LEFT_TEXT; hj<=RIGHT_TEXT; hj++) for (vj=LEFT_TEXT; vj<=RIGHT_TEXT; vj++) { cleardevice();/* set the text justification */ settextjustify(hj, vj);/* create a message string */ sprintf(msg, "%s %s", hjust[hj], vjust[vj]);/* create cross hairs on the screen */ xat(midx, midy);/* output the message */ outtextxy(midx, midy, msg); getch(); }/* clean up */ closegraph(); return 0;}/* draw an "x" at (x, y) */void xat(int x, int y){ line(x-4, y, x+4, y); line(x, y-4, x, y+4);}
