有关线形设定和画线函数的例子
有关线形设定和画线函数的例子如下:
#include "stdlib.h"
#include "graphics.h"
main()
{
int gdriver=DETECT, gmode, i;
initgraph(&gdriver, &gmode, "");
setbkcolor(RED);
cleardevice();
setcolor(BLUE);
circle(320,240,50);
circle(320,240,100);
setlinestyle(0, 0, 3); /*设置三点宽实线*/
setcolor(2);
rectangle(220, 140, 420, 340);
setcolor(WHITE);
setlinestyle(4, 0xaaaa, 1); /*设置一点宽用户定义线*/
line(220, 240, 420, 240);
line(320, 140, 320, 340);
getch();
closegraph();
}
