graphics.h是針對DOS下的一個C語言圖形庫 (c++也可以)
目前支持下載此頭文件的常用的有兩種:
1. EGE (Easy Graphics Engine)
2. EasyX Graphics Library
EGE, 全名Easy Graphics Engine, 是windows下的簡易繪圖庫，是一個類似BGI(graphics.h)的面向C/C++語言新手的圖形庫
EasyX, 全名EasyX Graphics Library, 是針對 Visual C++ 的免費繪圖庫，支持 VC6.0 ~ VC2022，簡單易用，學習成本極低，應用領域廣泛。目前已有許多大學將 EasyX 應用在教學當中
我建議Visual Studio用EasyX, Dev-C++可以用EGE
解決的方法：去 EasyX官網 下載EasyX的exe程序，點擊后直接對自己使用的VC版本進行安裝就行了，很簡單。.
Graphics.h常用用法:
1.initgraph(width, height)和closegraph()
initgraph可以創(chuàng)建一個寬度為width, 高度為height的圖形界面窗口
運行結束后可以通過closegraph來關閉窗口
注, closegraph之前記得用getch()函數(shù)來接收用戶輸入, 防止程序剛繪畫玩就關閉窗口了
2.line(x1,y1,x2,y2)
從x1,y1坐標畫一條直線到x2,y2坐標
3.setcolor和RGB
setcolor()可以把line畫出來的直線變成另外一種顏色
RGB可以返回setcolor的自定義參數(shù)
RGB(r,g,b)可以修改不同濃度的紅, 綠, 藍
EX:
setcolor(RGB(200,0,0))可以將line畫出來的直線變成紅色
4.circle(x,y,radius)
在x,y坐標點畫一個半徑為radius的圓
EX:
circle(200, 200, 100);
5.setfillcolor, bar(x1,y1,x2,y2)
bar函數(shù)可以畫出一個矩形
范圍為：x坐標從50-300，y坐標從100-200
setfillcolor()可以改變Bar的填充顏色值,參數(shù)也是RGB()函數(shù)的自定義顏色
6.fillellipse(x,y,xr,yr);
畫一個在x, y坐標點的實心橢圓
x軸上的半徑為xr
y軸上的半徑為yr
注:setfillcolor也可以改變其填充顏色值
7.setfontbkcolor(), setfont(12, 0, "宋體")
setfontcolor可以修改創(chuàng)建的文字的背景顏色值
setfont(12,0,"宋體")的第一個參數(shù)是字體的高度
第二個參數(shù)是字體的寬度, 如果填0, 那就會使用默認比例值
第三個參數(shù)是設置文字的字體樣式
8.outtextxy(x, y, 字符串);
這個函數(shù)可以在坐標x,y坐標點輸出字符串
注:字符串也可以是中文
EX:
outtextxy(100, 150, "中文也是支持的");
