基本框架
#include "graphics.h"

main()
{
    int driver=VGA,model=VGAHI;
    initgraph(&driver,&model,"");
    setbkcolor(EGERGB(0x00, 0xFF, 0x00));
    setcolor(RED);
    circle(200,200,20);
    getch();
}

随机圆
#include "graphics.h"
#include "time.h"

main()
{
    srand(time(0));
    int driver=VGA,model=VGAHI;
    initgraph(&driver,&model,"");
    setbkcolor(BLACK);
    while(1)
    {
        setcolor(RGB(rand()%256, rand()%256, rand()%256));
        circle(rand()%1000,rand()%800,rand()%500);
        Sleep(100);

    }
    getch();
}

随机方块
#include "graphics.h"
#include "time.h"

main()
{
    srand(time(0));
    int x1,y1,x2,y2;
    int driver=VGA,model=VGAHI;
    initgraph(&driver,&model,"");
    ege::initgraph(1000,800);
    setbkcolor(BLACK);
    while(1)
    {
        setfillstyle(SOLID_FILL,RGB(rand()%256, rand()%256, rand()%256));
        x1=rand()%1000+1;
        y1=rand()%800+1;
        x2=rand()%1000+1;
        y2=rand()%800+1;
        bar(x1,y1,x2,y2);
        Sleep(100);

    }
    getch();
}

其他常用绘图功能
#include "graphics.h"
#include "time.h"

main()
{
    srand(time(0));
    int x1,y1,x2,y2,i;
    int driver=VGA,model=VGAHI;

    setcolor(RGB(rand()%156+100,rand()%156+100,rand()%156+100));
    circle(100,100,100);
    for(i=0; i<10; i++)
        putpixel(300+i,300,WHITE);
    setlinestyle(DOTTED_LINE,0,1);
    line(100,100,300,300);
    rectangle(400,400,500,500);
    setviewport(400,400,500,500,1);
    setcolor(GREEN);
    setlinestyle(SOLID_FILL,0,1);
    rectangle(10,10,90,90);
    setfont(60, 60, "宋体");
    outtextxy(20,20,"A");
    getch();
}

 

国际象棋
#include "graphics.h"

main()
{
    int driver=VGA,model=VGAHI;
    int i=0,j=0;
    initgraph(&driver,&model,"");
    ege::initgraph(800,800);
    setbkcolor(WHITE);
    setcolor(BLACK);
    for(i=0; i<8; i++)
        for(j=0; j<8; j++)
        {
            if(i%2==0)
            {
                bar(i*100,j*100,(i+1)*100,(j+1)*100);
                j++;
            }
            if(i%2==1)
            {
                j++;
                bar(i*100,j*100,(i+1)*100,(j+1)*100);
            }
        }
    getch();

鼠标处理
#include "graphics.h"
#include "stdio.h"
#include "stdlib.h"

main()
{
    int driver=VGA,model=VGAHI;
    int i=0,j=0;
    initgraph(&driver,&model,"");
    ege::initgraph(800,800);

    {
        while (mousemsg())
        {
            mouse_msg m = getmouse();
            if (m.msg == mouse_msg_down)
            {
                bar(m.x-2, m.y-2,m.x+2, m.y+2);
            }
        }
    }

#include "graphics.h"

main()
{
    int driver=VGA,model=VGAHI;
    initgraph(&driver,&model,"");
    setbkcolor(RGB(100,100,100));
    setlinestyle(SOLID_LINE,0,3);
    setcolor(WHITE);
    line(100,100,300,100);
    line(100,100,100,150);
    setcolor(BLACK);
    line(300,100,300,150);
    line(100,150,300,150);
    for ( ; is_run(); delay_fps(120))
    {
        while (mousemsg())
        {
            mouse_msg m = getmouse();
            if (m.msg == mouse_msg_down)
            {
                setcolor(BLACK);
                line(100,100,300,100);
                line(100,100,100,150);
                setcolor(WHITE);
                line(300,100,300,150);
                line(100,150,300,150);
            }
            else
            {
                setcolor(WHITE);
                line(100,100,300,100);
                line(100,100,100,150);
                setcolor(BLACK);
                line(300,100,300,150);
                line(100,150,300,150);
            }
        }
    }
