Bài 5 - Kỹ thuật đồ họa - Vẽ đền Tajmaha

Tāj Mahal (tiếng Urdu: تاج محل, tiếng Hindi: ताज महल) là một lăng mộ nằm tại Agra, Ấn Độ. Hoàng đế Môgôn Shāh Jahān (gốc Ba Tư, lên ngôi năm 1627); trong tiếng Ba Tư Shah Jahan (شاه ‌جها) có nghĩa là "chúa tể thế giới" đã ra lệnh xây nó cho người vợ yêu dấu của mình là Mumtaz Mahal.Công việc xây dựng bắt đầu năm 1632 và hoàn thành năm 1653. Một số tranh cãi xung quanh câu hỏi ai là người thiết kế Taj Mahal; rõ ràng một đội các nhà thiết kế và thợ thủ công đã chịu trách nhiệm thiết kế công trình và Ustad Ahmad Lahauri được coi là kiến trúc sư chính.

Tạo màu ngẫu nhiên từ 1 đến 15, ta có đoạn code sau:

#include <stdio.h>

#include <conio.h>

#include <graphics.h>

#include <time.h>

int main(){

    initwindow(800,600);

    srand((unsigned int) time(0));

    int t=0;

    while (1){

        for(int i=0;i<300;i=i+10){

Cách sử dụng hàm setbkcolor trong thư viện WinBGIm là phải sử dụng liên tục 2 câu lệnh setbkcolor(mau) và cleardevice(). 

Hàm settextstyle(font_chữ,hướng,kích_cỡ) dùng để thiết lập font chữ (0-10), hướng (trái sang phải - 0, dưới lên trên - 1) và cỡ chữ.

Xem ví dụ:

#include <stdio.h>

#include <graphics.h>

int main(){

    initwindow(500,300);

    setbkcolor(GREEN);

    cleardevice();

    settextstyle(10,0 ,5);

    moveto(50,100);

    outtext("Xin chao TH9");

    int maxx = getmaxx();//499

    int maxy = getmaxy();//299

    printf("%d  %d",maxx,maxy);

    int x = getx();//350

    int y = gety();//100

    printf("\n%d %d\n",x,y);

    getch();

    return 0;

}

Vẽ ngôi sao quay bằng cách sử dụng cấu trúc accoordstype và getarccoords:

    arccoordstype a;

    int g = 0;

    int c = 1;

    int gtang = 144;

    while (1){ //lap vo tan

        int gt = g;

        for(int i=0;i<5;i++){

            setcolor(BLACK);

            arc(400,300, gt,gt+gtang,200);

            getarccoords(&a);

            setcolor(c);

            line(a.xstart,a.ystart,a.xend,a.yend);

            gt=gt+gtang;

        }

        g+=5; //tang goc bat dau len 5 sau moi lan ve

        delay(100);

        c++;

        if (c==16)// mau thay doi nhung k vuot qua gioi han

            c=1;

        if (g==360) //goc tang nhung k vuot qua gioi han

            g=0;

        cleardevice();//xoa man hinh
