前面看过我文章的都知道本人喜欢用pythonnet, 温故而知新,先说python嵌入.net.
首先: 需要安装 安装.偷个懒. 贴上上次的下载脚本. 后面需要什么直接往后面添..
import os
def cmd(S="pause"):
os.system(S)
def P_install(S="mvtec-halcon==20111"):
cmd(rf"pip install {S} -i https://pypi.doubanio.com/simple")
IN_list=[
"mvtec-halcon==20111","pythonnet",
"pywin32","pyautogui","keyboard","Pyinstaller",
"pillow","numpy","opencv-python"
]
for i in IN_list:
P_install(f"{i}")
while True:
cmd(rf"pip list"); CMD=input("请输入:");
cmd(rf"pip install {CMD} -i https://pypi.doubanio.com/simple"); 如果计算机只有一个python环境 并且3.5以上3.10以下理论上都可以用. 顺便提一下,3.7以下版本不支持f字符串,所以老版本需要占位符+.format(). #大概就有这么回事..
接下来:导入clr ,下来C#那一套命名空间就可以当作python自己的包导入进来了.
#--------------------------------------------------------------------------
import clr
import System
from System import String, Char, Int32,UInt16, Int64, Environment, IntPtr
print(f"{clr.AddReference('System')}")
print(f"{clr.AddReference('System.Drawing')}")
#---------------------------------------------------------------------------导入以后,就可以开心的写程序了. 我先来,在python里用>NET,写一个图片格式转换.
from tkinter import ttk
from tkinter import messagebox
from tkinter import *
import tkinter as tk
import tkinter.messagebox
import os,sys,time
import tkinter.filedialog
from ctypes import *
from tkinter import Tk,Frame
def cmd(s="pause"):
os.system(s)
#--------------------------------------------------------------------------
import clr
import System
from System import String, Char, Int32,UInt16, Int64, Environment, IntPtr
print(f"{clr.AddReference('System')}")
print(f"{clr.AddReference('System.Drawing')}")
#---------------------------------------------------------------------------
文件名="11"
R=f"{文件名}.bmp"
W=f"{文件名}.jpg"
System.Drawing.Bitmap(f"{R}").Save(f"{W}",System.Drawing.Imaging.ImageFormat.Jpeg);
print("done!")
time.sleep(2)
#cmd()可以看到主要就是这一句;
System.Drawing.Bitmap(f"{R}").Save(f"{W}",System.Drawing.Imaging.ImageFormat.Jpeg);脚本同级目录放一张 “11.bmp”的图片. 运行之后 会生成 “11.jpg”的图,
尺寸从1282变成了98,尺寸缩小了十几倍.而图像精度几乎没有损失.
接下来:贴一个官方例子:
