使用python制作一个压缩图片小程序
更新时间:2023年10月27日 16:30:11 作者:hbqjzx
这篇文章主要为大家详细介绍了如何使用python制作一个压缩图片小程序,文中的示例代码简洁易懂,具有一定的学习价值,感兴趣的小伙伴可以了解下
学生正在学习图像的编码与压缩,记录一下这个python小程序,给他们提供一下帮助。需要用到PIL库,记得安装:
pip install pillow
完整代码
import tkinter as tk from tkinter import filedialog from PIL import Image import tkinter.messagebox as messagebox class ImageCompressor: def __init__(self, window): self.window = window self.window.title("图片压缩工具By ZYX 2023") self.source_path = tk.StringVar() self.output_path = tk.StringVar() frame1 = tk.Frame(window) frame1.pack(padx=5, pady=5) lbl_source = tk.Label(frame1, text="原始图片路径:") lbl_source.pack(side=tk.LEFT) entry_source = tk.Entry(frame1,textvariable=self.source_path, width=40) entry_source.pack(side=tk.LEFT) btn_source =tk.Button(frame1, text="打开", command=self.open_source_image) btn_source.pack(side=tk.LEFT) frame2 = tk.Frame(window) frame2.pack(padx=5, pady=5) lbl_output = tk.Label(frame2, text="输出图片路径:") lbl_output.pack(side=tk.LEFT) entry_output = tk.Entry(frame2,textvariable=self.output_path, width=40) entry_output.pack(side=tk.LEFT) btn_output =tk.Button(frame2, text="保存", command=self.save_output_image) btn_output.pack(side=tk.LEFT) quality_label = tk.Label(window, text='质量(1-95):') quality_label.pack(pady=5) self.quality_slider = tk.Scale(window, from_=1, to=95, length=400,tickinterval=19, orient='horizontal', resolution=1) self.quality_slider.set(80) self.quality_slider.pack() btn_compress =tk.Button(window, text="开始压缩", command=self.compress_image) btn_compress.pack(pady=10) def open_source_image(self): file_path = filedialog.askopenfilename() self.source_path.set(file_path) def save_output_image(self): file_path = filedialog.asksaveasfilename(defaultextension=".jpg") self.output_path.set(file_path) def compress_image(self): try: img = Image.open(self.source_path.get()) img.save(self.output_path.get(), "JPEG", quality=self.quality_slider.get()) messagebox.showinfo("成功", "图片压缩成功!") except Exception as e: messagebox.showerror("失败", f"压缩过程中发生错误:{e}") if __name__ == '__main__': window = tk.Tk() app = ImageCompressor(window) window.mainloop()
知识补充
除了上文的方法,小编还为大家整理了其他python压缩图片的方法,希望对大家有所帮助
使用PIL库压缩图片大小(按比例压缩)
from PIL import Image infile = 'cxq1.jpg' outfile = 'cxq2.jpg' im = Image.open(infile) (x,y) = im.size #read image size x_s = 1000 #define standard width y_s = int(y * x_s / x) #calc height based on standard width out = im.resize((x_s,y_s)) #resize image with high-quality out.save(outfile) print('original size: ',x,y) print('adjust size: ',x_s,y_s)
Python实现批量压缩图片 无大小限制
