python 实现turtle画图并导出图片格式的文件

今天小编就为大家分享一篇python 实现turtle画图并导出图片格式的文件，具有很好的参考价值，希望对大家有所帮助。一起跟随小编过来看看吧

python turtle导出图片工具

import turtle def draw_ring(radius, color): turtle.pendown() turtle.color(color) turtle.circle(radius) turtle.penup() def draw_olympic_rings(): turtle.speed(10) turtle.penup() colors = ["blue", "black", "red", "yellow", "green"] for i in range(5): turtle.goto(i * 120, 0) draw_ring(50, colors[i]) turtle.hideturtle() draw_olympic_rings() turtle.done()

这段代码是一个 Python 程序，使用了 turtle 库来绘制奥林匹克五环图案。它定义了两个函数： 1. draw_ring(radius, color)：绘制半径为 radius，颜色为 color 的圆环。 2. draw_olympic_rings()：绘制奥林匹克五环...

import turtle from PIL import Image def draw_image(image): turtle.speed(0) turtle.penup() turtle.goto(-250, 250) turtle.pendown() for row in image: for pixel in row: if pixel == 1: turtle.forward(10) else: turtle.penup() turtle.forward(10) turtle.pendown() turtle.penup() turtle.backward(len(row)10) turtle.right(90) turtle.forward(10) turtle.left(90) turtle.pendown() filename = "image.jpg" image = get_image_data(filename) draw_image(image) turtle.done() def get_image_data(filename): # 打开图片 image = Image.open(filename) # 将图片转换为黑白模式 image = image.convert('1') # 获取图片的宽度和高度 width, height = image.size # 创建一个二维数组来存储图片数据 data = [[0]width for _ in range(height)] # 遍历图片的每个像素点，将其值存储到二维数组中 for y in range(height): for x in range(width): pixel = image.getpixel((x, y)) data[y][x] = pixel return data调整代码缩进

turtle.goto(-250, 250) turtle.pendown() for row in image: for pixel in row: if pixel == 1: turtle.forward(10) else: turtle.penup() turtle.forward(10) turtle.pendown() turtle.penup() turtle...

import turtle def draw_heart(): turtle.color('red') turtle.begin_fill() turtle.left(140) turtle.forward(180) turtle.circle(-90, 200) turtle.setheading(60) turtle.circle(-90, 200) turtle.forward(180) turtle.end_fill() turtle.speed(0) turtle.penup() turtle.goto(0, 0) turtle.pendown() draw_heart() turtle.hideturtle() turtle.done()在这段代码基础上加个闪烁效果

import turtle import time def draw_heart(): ...turtle.goto(0, 0) turtle.pendown() while True: draw_heart() time.sleep(0.5) turtle.clear() time.sleep(0.5) turtle.hideturtle() turtle.done()

import turtle def draw_balloon(): # 设置画笔和填充颜色 turtle.pensize(3) turtle.fillcolor("#FF69B4") # 粉色 # 绘制气球的主体 turtle.begin_fill() turtle.circle(100) turtle.end_fill() def draw_text(): # 设置字体样式和大小 turtle.penup() turtle.color("#FFFFFF") # 白色 turtle.goto(-40, -10) turtle.pendown() turtle.write("六一儿童节", align="left", font=("Arial", 16, "bold")) turtle.penup() turtle.goto(-40, -40) turtle.pendown() turtle.write("快乐", align="left", font=("Arial", 16, "bold")) def main(): turtle.speed(2) # 设置绘制速度 draw_balloon() draw_text() turtle.hideturtle() # 隐藏海龟箭头 turtle.done() # 结束绘制 if name == "main": main()

首先定义一个名为draw_balloon的函数来绘制气球的主体，然后定义一个名为draw_text的函数来在气球上写字。最后定义一个名为main的函数来调用这两个函数，并设置绘制速度、隐藏海龟箭头以及结束绘制。如果在命令行中...

import turtle # 创建一个窗口和画笔对象 window = turtle.Screen() pen = turtle.Turtle() # 设置画笔的初始位置和形状 pen.penup() import turtle def draw_star(size, points, color, x, y): angle = 360 / points outer_angle = 180 - angle turtle.penup() turtle.goto(x, y) turtle.pendown() turtle.color(color) turtle.begin_fill() for i in range(points): turtle.forward(size) turtle.right(outer_angle) turtle.forward(size) turtle.right(180 - angle) turtle.end_fill() draw_star(100, 9090, "red", 0, 0) 解释一下

import turtle # create a turtle my_turtle = turtle.Turtle() # move the turtle forward by 100 units my_turtle.forward(100) # turn the turtle left by 90 degrees my_turtle.left(90) # move the turtle ...

运行这个代码：import turtle def draw_balloon(): # 设置画笔和填充颜色 turtle.pensize(3) turtle.fillcolor("#FF69B4") # 粉色 # 绘制气球的主体 turtle.begin_fill() turtle.circle(100) turtle.end_fill() def draw_text(): # 设置字体样式和大小 turtle.penup() turtle.color("#FFFFFF") # 白色 turtle.goto(-40, -10) turtle.pendown() turtle.write("六一儿童节", align="left", font=("Arial", 16, "bold")) turtle.penup() turtle.goto(-40, -40) turtle.pendown() turtle.write("快乐", align="left", font=("Arial", 16, "bold")) def main(): turtle.speed(2) # 设置绘制速度 draw_balloon() draw_text() turtle.hideturtle() # 隐藏海龟箭头 turtle.done() # 结束绘制 if name == "main": main()

1. 将代码保存为一个.py文件，例如 "draw_balloon.py"。 2. 打开终端（或命令提示符）并进入保存了代码文件的目录。 3. 输入以下命令来运行代码： python draw_balloon.py 4. 如果一切正常，你将看到一...

28. 使用 turtle 库函数绘制4个等距排列的正方形，边长为40像素，间距宽度为40。最左边的正方形左上角坐标为(0,0)。 import turtle n = (1) for j in range(n): turtle. (2) for i in range(4): turtle. (3) turtle.right((4)) turtle.penup() turtle.fd((5)) turtle.done()

import turtle n = 4 for j in range(n): turtle.penup() turtle.goto(j*80, 0) turtle.pendown() for i in range(4): turtle.fd(40) turtle.right(90) turtle.penup() turtle.fd(40) turtle.done()

import turtle def koch(size, n): if n == 0: turtle.fd(size) else: for angle in [0, 60, -120, 60]: turtle.left(angle) koch(size/3, n-1) def main(): turtle.setup(800,400) turtle.speed(1) turtle.penup() turtle.goto(-300,-50) turtle.pendown() turtle.pensize(2) koch(600,3) turtle.hideturtle() main() 使科赫曲线反向绘制，从直线开始，中间部分呢向下方绘制。

import turtle def koch(size, n): if n == 0: turtle.fd(size) else: for angle in [0, -60, 120, -60]: turtle.right(angle) # 左转角度改为右转角度，右转角度改为左转角度 koch(size/3, n-1) def main()...

import turtle def setPen(): turtle.setup(width=0.9, height=0.8) turtle.pensize(10) turtle.speed(10) def movePen(x,y): turtle.penup() turtle.goto(x,y) turtle.pendown() def drawing(): setPen() x,y=-275,0 penColor=['blue','black','red','yellow','green'] for i in range(5): if i<3: movePen(x+i230,y) turtle.pencolor(penColor[i]) turtle.circle(100) if i==3: x,y=-155,-105 if i>=3: movePen(x + (i-3) 230, y) turtle.pencolor(penColor[i]) turtle.circle(100) turtle.hideturtle() if name=='main': drawing() turtle.done()

这段代码是使用 Python 的 turtle 库绘制一个五环图案。首先定义了三个函数，setPen() 用于设置画笔属性，movePen(x,y) 用于移动画笔到指定位置，drawing() 函数则是实际的绘图代码。在 drawing() 函数中，先调用 ...

修改代码使图中的小圆绕大圆圈的圆心以200圈每秒的速度进行圆周运动：import turtle import math # Set up the turtle screen screen = turtle.Screen() screen.bgcolor("white") screen.title("Circle with Moving Black Dot") # Create the turtle for drawing the circle circle_turtle = turtle.Turtle() circle_turtle.speed(0) circle_turtle.hideturtle() circle_turtle.penup() circle_turtle.goto(0, -80) circle_turtle.pendown() circle_turtle.color("black") circle_turtle.circle(80, 2880) # Create the turtle for drawing the black dot dot_turtle = turtle.Turtle() dot_turtle.speed(0) dot_turtle.hideturtle() dot_turtle.penup() dot_turtle.goto(40, 0) dot_turtle.pendown() dot_turtle.color("black") dot_turtle.begin_fill() dot_turtle.circle(4) dot_turtle.end_fill() # Calculate the angle increment for each frame of animation angle_increment = 1 / 60 # 200 degrees per second, 60 frames per second # Animate the movement of the black dot while True: dot_turtle.clear() angle = dot_turtle.heading() + angle_increment x = 40 * math.cos(math.radians(angle)) y = 40 * math.sin(math.radians(angle)) dot_turtle.goto(x, y) dot_turtle.begin_fill() dot_turtle.circle(6) # 小圆 dot_turtle.end_fill()

circle_turtle.speed(0) circle_turtle.hideturtle() circle_turtle.penup() circle_turtle.goto(0, -80) circle_turtle.pendown() circle_turtle.color("black") circle_turtle.circle(80, 2880) # Create ...

import turtle import datetime # 画刻度线 def draw_scale(t, length, num): # 移动到起点 t.penup() t.right(90) t.forward(10) t.right(180) t.pendown() # 绘制刻度线 for i in range(num): t.forward(length) t.penup() t.backward(length) t.left(360 / num) t.pendown() # 画指针 def draw_hand(t, length, thickness, angle): t.penup() t.right(90) t.forward(10) t.right(180 - angle) t.pensize(thickness) t.pendown() t.forward(length) # 获取当前时间 now = datetime.datetime.now() # 创建 Turtle 对象 t = turtle.Turtle() t.speed(0) # 设置画布和画笔属性 turtle.setup(400, 400) turtle.bgcolor("white") t.pensize(3) t.pencolor("black") # 画钟表框 t.penup() t.goto(0, 0) t.pendown() t.circle(100) # 画刻度线和数字 draw_scale(t, 80, 12) # 画时针、分针和秒针 hour = now.hour % 12 minute = now.minute second = now.second hour_angle = (hour + minute / 60) * 30 minute_angle = minute * 6 second_angle = second * 6 draw_hand(t, 50, 5, hour_angle) draw_hand(t, 70, 3, minute_angle) draw_hand(t, 90, 1, second_angle) # 隐藏 Turtle 对象 t.hideturtle() # 保持窗口不关闭 turtle.mainloop()

代码中使用了两个函数，一个是 draw_scale() 函数，用于绘制时钟刻度线和数字，另一个是 draw_hand() 函数，用于绘制时针、分针和秒针。在代码中首先创建了一个 Turtle 对象 t，并设置了画布和画笔属性。然后绘制...

下面的代码要小海龟绘制一个以(-100, -20)这个点为左上角的边长为50的正方形，请补齐代码。 import turtle t = turtle.Turtle() t.speed(2) t.penup() ____ t.pendown() for i in range(4): # 循环结构，下面两行缩进的代码会重复执行4次 t.forward(50) t.getscreen().exitonclick()

import turtle t = turtle.Turtle() t.speed(2) t.penup() t.goto(-100, -20) # 移动到左上角 t.pendown() for i in range(4): t.forward(50) # 前进50步 t.right(90) # 右转90度这段代码首先创建了一个...

from PIL import Image import numpy as np import turtle # 加载图像 img = Image.open("image.png") width, height = img.size # 图像分割，获取人物像素数据 data = np.array(img.convert("RGBA")) alpha = data[:, :, 3] mask = alpha > 0 person = np.zeros_like(data) person[mask] = data[mask] # 获取人物像素的矩形区域 non_empty_columns = np.where(person.max(axis=0) > 0)[0] non_empty_rows = np.where(person.max(axis=1) > 0)[0] xmin, xmax = non_empty_columns.min(), non_empty_columns.max() ymin, ymax = non_empty_rows.min(), non_empty_rows.max() # 初始化turtle turtle.setup(xmax - xmin + 50, ymax - ymin + 50) turtle.speed(3) turtle.hideturtle() turtle.penup() # 遍历人物像素并转换为turtle指令 for y in range(ymin, ymax+1): for x in range(xmin, xmax+1): if mask[y, x]: turtle.goto(x - width // 2 - xmin, ymax - y + 25) turtle.pendown() else: turtle.penup() # 显示turtle turtle.done()加快绘画速度，跳过空白区域

这段代码似乎是Python语言实现的，使用了PIL库、numpy库和turtle库，目的是将一张PNG格式的图像中的人物像素转换为turtle指令，并使用turtle绘制出人物的轮廓。为了加快绘画速度和跳过空白区域，代码使用了以下...
