奥特曼的组成
奥特曼是由斜的椭圆,圆角矩形,圆形,以及曲线的组成的。此处绘制中,主要应用了曲线的的绘制,将奥特曼画的比较饱满。
值得学习的地方
本次绘制过过程中,自己编写了两个函数。一个是绘制有倾斜角的椭圆,用来表示奥特曼的眼睛,这样可以使得奥特曼更加有灵魂。另一个是心形。再平时绘制别的东西时,如果需要,可以直接借鉴。
代码如下:
#include<conio.h>
#include<graphics.h>
#include<math.h>
#define PI acos(-1.0)
double th = PI / 180;// 绘制斜的椭圆
void DrawEllipse(int x0, int y0, int a, int b, int k, int color);
// 绘制心形
void heart(int x0, int y0, int size, COLORREF C);int main()
{initgraph(640, 640);setbkcolor(WHITE);cleardevice();// 设置线的宽度setlinestyle(PS_SOLID, 5);setlinecolor(BLACK);setfillcolor(RGB(238, 238, 238));// 左耳朵fillrectangle(175, 266, 190, 325);fillrectangle(159, 281, 175, 315);// 右耳朵fillrectangle(393, 268, 410, 324);fillrectangle(410, 286, 423, 311);fillellipse(187, 196, 397, 402);setfillcolor(WHITE);fillroundrect(288, 146, 302, 242, 10, 20);// 绘制左右眼睛DrawEllipse(243, 297, 38, 30, -30, BLACK);DrawEllipse(350, 297, 38, 30, 30, BLACK);setfillcolor(RGB(248, 245, 143));floodfill(243, 297, BLACK);floodfill(350, 297, BLACK);line(296, 422, 249, 394);line(296, 422, 336, 394);setfillcolor(RGB(235, 110, 69));floodfill(295, 410, BLACK);setfillcolor(RGB(137, 211, 211));fillcircle(294, 432, 10);// 绘制身体arc(222, 399, 286, 591, 145.0 / 180 * PI, PI + 145.0 / 180 * PI);arc(305, 413, 364, 591, PI + 35.0 / 180 * PI, 55.0 / 180 * PI);line(224, 485, 359, 485);line(224, 511, 278, 549);line(278, 549, 312, 549);line(312, 549, 360, 515);setfillcolor(RGB(235, 110, 69));floodfill(294, 517, BLACK);setfillcolor(RGB(238, 238, 238));floodfill(252, 554, BLACK);floodfill(334, 559, BLACK);// 绘制左边胳膊arc(189, 387, 353, 647, 109.0 / 180 * PI, PI);arc(189, 480, 223, 537, 10.0 / 180.0 * PI + PI, 0);line(196, 471, 222, 491);setfillcolor(RGB(235, 110, 69));floodfill(207, 501, BLACK);// 绘制右胳膊arc(230, 319, 424, 455, 110.0 / 180 * PI + PI, 5.0 / 180 * PI);arc(392, 360, 424, 395, -5.0 / 180 * PI, PI + PI / 2);arc(310, 286, 402, 394, 70.0 / 180 * PI + PI, 150.0 / 180 * PI + PI);line(372, 390, 394, 431);setfillcolor(RGB(235, 110, 69));floodfill(399, 402, BLACK);// 给身体颜色setfillcolor(RGB(238, 238, 238));floodfill(296, 458, BLACK);// 连接气球line(463, 187, 422, 365);heart(464, 67, 30, BLACK);setfillcolor(RGB(235, 110, 69));floodfill(464, 70, BLACK);setfillcolor(RGB(255, 232, 201));solidcircle(508, 70, 6);_getch();return 0;

}
效果如图:
