python——生成带logo的二维码图片并且保存、控制打印机打印图片二维码、整合打印（获取输入框的值）、打包成exe文件

1、生成带logo的二维码图片并且保存

前提条件：在D盘里有logo.png的图片，生成的二维码图片在D盘里的111.png

import qrcode
from PIL import Image# 前提条件：在D盘里有logo.png的图片，生成的二维码图片在D盘里的111.png
def create_qrcode(url, filename):qr = qrcode.QRCode(version=1,# 设置容错率为最高error_correction=qrcode.ERROR_CORRECT_H,box_size=10,border=4,)qr.add_data(url)qr.make(fit=True)img = qr.make_image()# 设置二维码为彩色img = img.convert("RGBA")icon = Image.open('D:/logo.png')w, h = img.sizefactor = 4size_w = int(w / factor)size_h = int(h / factor)icon_w, icon_h = icon.sizeif icon_w > size_w:icon_w = size_wif icon_h > size_h:icon_h = size_hicon = icon.resize((icon_w, icon_h), Image.ANTIALIAS)w = int((w - icon_w) / 2)h = int((h - icon_h) / 2)icon = icon.convert("RGBA")# 这里可以修改宽度newimg = Image.new("RGBA", (icon_w + 5, icon_h + 5), (255, 255, 255))img.paste(newimg, (w - 4, h - 4), newimg)img.paste(icon, (w, h), icon)img.save('D:/' + filename + '.png', quality=100)if __name__ == "__main__":create_qrcode('https://blog.csdn.net/wy313622821?spm=1011.2124.3001.5343', "111")

2、控制打印机打印图片二维码

背景：需要打印二维码图片，保证手动能够打开图片并且点打印可以打印出来（安装了对应的打印机驱动）
代码为：

import win32print
import win32ui
from PIL import Image, ImageWin#
# Constants for GetDeviceCaps
#
#
# HORZRES / VERTRES = printable area
#
HORZRES = 30
VERTRES = 30
#
# LOGPIXELS = dots per inch
#
# LOGPIXELSX = 40
# LOGPIXELSY = 45
#
# PHYSICALWIDTH/HEIGHT = total area
#
PHYSICALWIDTH = 30
PHYSICALHEIGHT = 30
#
# PHYSICALOFFSETX/Y = left / top margin
#
PHYSICALOFFSETX = 112
PHYSICALOFFSETY = 113printer_name = win32print.GetDefaultPrinter()
file_name = "test.jpg"#
# You can only write a Device-independent bitmap
# directly to a Windows device context; therefore
# we need (for ease) to use the Python Imaging
# Library to manipulate the image.
#
# Create a device context from a named printer
# and assess the printable size of the paper.
#
hDC = win32ui.CreateDC()
hDC.CreatePrinterDC(printer_name)
printable_area = hDC.GetDeviceCaps(HORZRES), hDC.GetDeviceCaps(VERTRES)
printer_size = hDC.GetDeviceCaps(PHYSICALWIDTH), hDC.GetDeviceCaps(PHYSICALHEIGHT)
printer_margins = hDC.GetDeviceCaps(PHYSICALOFFSETX), hDC.GetDeviceCaps(PHYSICALOFFSETY)#
# Open the image, rotate it if it's wider than
# it is high, and work out how much to multiply
# each pixel by to get it as big as possible on
# the page without distorting.
#
bmp = Image.open(file_name)
if bmp.size[0] > bmp.size[1]:bmp = bmp.rotate(90)ratios = [1.0 * printable_area[0] / bmp.size[0], 1.0 * printable_area[1] / bmp.size[1]]
scale = min(ratios)#
# Start the print job, and draw the bitmap to
# the printer device at the scaled size.
#
hDC.StartDoc(file_name)
hDC.StartPage()dib = ImageWin.Dib(bmp)
scaled_width, scaled_height = [int(scale * i) for i in bmp.size]
x1 = int((printer_size[0] - scaled_width) / 2)
y1 = int((printer_size[1] - scaled_height) / 2)
x2 = x1 + scaled_width
y2 = y1 + scaled_height
dib.draw(hDC.GetHandleOutput(), (x1, y1, x2, y2))hDC.EndPage()
hDC.EndDoc()
hDC.DeleteDC()

3、整合

import tkinter
import win32print
import win32ui
from PIL import Image, ImageWin
import qrcode
import pyperclip# 前提条件：在D盘里有logo.png的图片，生成的二维码图片在D盘里的111.png
# 打包成exe文件：1、在Terminal中安装pip install pyinstaller
# 2、在Terminal中 pyinstaller.exe -F print2.py，把print2.py文件放到build文件夹里
# 3、生成的exe就放在dis里面#
# 使用字符串生成二维码图片
#
def create_qrcode(url, filename):qr = qrcode.QRCode(version=1,# 设置容错率为最高error_correction=qrcode.ERROR_CORRECT_H,box_size=10,border=4,)qr.add_data(url)qr.make(fit=True)img = qr.make_image()# 设置二维码为彩色img = img.convert("RGBA")# icon = Image.open('D:/logo.png')icon = Image.open('logo.png')w, h = img.sizefactor = 4size_w = int(w / factor)size_h = int(h / factor)icon_w, icon_h = icon.sizeif icon_w > size_w:icon_w = size_wif icon_h > size_h:icon_h = size_hicon = icon.resize((icon_w, icon_h), Image.ANTIALIAS)w = int((w - icon_w) / 2)h = int((h - icon_h) / 2)icon = icon.convert("RGBA")# 这里可以修改宽度newimg = Image.new("RGBA", (icon_w + 5, icon_h + 5), (255, 255, 255))img.paste(newimg, (w - 4, h - 4), newimg)img.paste(icon, (w, h), icon)img.save(filename + '.png', quality=100,dpi=(600.0,600.0))#
# 使用默认打印机打印二维码图片
#

4、打包成exe文件

1、在Terminal中安装pip install pyinstaller
2、在Terminal中 pyinstaller.exe -F print2.py，把print2.py文件放到build文件夹里，不要黑色的空窗口的打包：pyinstaller.exe -w -F print2.py
总结命令：
Pyinstaller -F setup.py 打包exe
Pyinstaller -F -w setup.py 不带控制台的打包
Pyinstaller -F -i xx.ico setup.py 打包指定exe图标打包
3、生成的exe就放在dis里面
