自制python 終端畫布模塊

python在終端繪制一個畫布：consoleCanvas

效果如圖 ：

 

已發布到pypi

https://pypi.org/project/ConsoleCanvas/

 

Project description

ConsoleCanvas用法：

0.安裝

pip install ConsoleCanvas -i https://pypi.python.org/simple

 

0.1.終端顯示cv2的img：

import consoleCanvas,cv2
img=cv2.imread("C:\\Users\\Administrator\\Desktop\\1.png")
consoleCanvas.cvShow(img)

1.先初始化對象：

import consoleCanvas
A=consoleCanvas.consoleCanvas()

 

2.生成畫布：

A.ProduceCanvas(80,80)#創建畫布

 

3.繪制像素點：

A.reviseCanvas([x,y],1)
#[x,y]是坐標，1是代表繪制黑色點，0是繪制白色點

 

4.顯示畫布：

A.show() #顯示畫布

 

5.清空畫布：

A.ProduceCanvas(80,80)#也就是重新創建畫布

 

6.例子

#繪制圓形
import consoleCanvas
a=10
b=10
r=10
A=consoleCanvas.consoleCanvas()#初始化
A.ProduceCanvas(21,21)#創建畫布
A.reviseCanvas([0,0],1)
for x in range(a-r,a+r):
    y=int((((r**2)-(x-a)**2)**(1/2))+b)
    A.reviseCanvas([x,y],1)#繪制畫布像素
for x in range(a+r,a-r,-1):
    y=int(-1*(((r**2)-(x-a)**2)**(1/2))+b)
    A.reviseCanvas([x,y],1)#繪制畫布像素
A.show() #顯示畫布

 

輸出:
