Python实现批量把SVG格式转成png、pdf格式的代码分享
需要提前安装cairosvg模块,下载地址http://cairosvg.org/download/
Code:
#! encoding:UTF-8 import cairosvg import os loop = True while loop: svgDir = raw_input("请输入SVG文件目录") if os.path.exists(svgDir) and os.path.isdir(svgDir): loop = False else: print "错误:您输入的SVG文件目录不存在或者不是一个有效的目录,请重新输入" loop = True while loop: exportDir = raw_input("请输入导出目录") if os.path.exists(exportDir): loop = False else: print "错误:您输入的导出目录[" , exportDir , "] 不存在,是否要创建这个目录?" loops = True while loops: msg = "" cmd = raw_input("创建 (Y) 重新 (R)") if cmd.upper() == "R": loops = False elif cmd.upper() == "Y": os.makedirs(exportDir, True) if os.path.exists(exportDir): loop = False loops = False else: print "创建目录失败[",exportDir,"], 请重新输入" else: print "找不到您输入的命令,请重新输入" cate = ("png", "pdf") print "导出类型:" for i in cate: print i loop = True while loop: exportFormat = raw_input("请输入导出类型") if exportFormat.lower() in cate: loop = False else: print "您输入的类型不存在,请重新输入" def export(fromDir, targetDir, exportType): print "开始执行转换命令..." files = os.listdir(fromDir) num = 0 for fileName in files: path = os.path.join(fromDir,fileName) if os.path.isfile(path) and fileName[-3:] == "svg": num += 1 fileHandle = open(path) svg = fileHandle.read() fileHandle.close() exportPath = os.path.join(targetDir, fileName[:-3] + exportType) exportFileHandle = open(exportPath,'w') if exportType == "png": cairosvg.svg2png(bytestring=svg, write_to=exportPath) elif exportType == "pdf": cairosvg.svg2pdf(bytestring=svg, write_to=exportPath) exportFileHandle.close() print "Success Export ", exportType, " -> " , exportPath print "已导出 ", num, "个文件" export(svgDir, exportDir, exportFormat)
使用:
请输入SVG文件目录d:\svg
请输入导出目录d:\images
错误:您输入的导出目录[ d:\images ] 不存在,是否要创建这个目录?
创建 (Y) 重新 (R)Y
导出类型:
png
请输入导出类型png
开始执行转换命令...
Success Export png -> d:\images\a.png
Success Export png -> d:\images\db2.png
Success Export png -> d:\images\db3.png
已导出 3 个文件

VS Code extensions pose malicious risks, such as hiding malicious code, exploiting vulnerabilities, and masturbating as legitimate extensions. Methods to identify malicious extensions include: checking publishers, reading comments, checking code, and installing with caution. Security measures also include: security awareness, good habits, regular updates and antivirus software.

In VS Code, you can run the program in the terminal through the following steps: Prepare the code and open the integrated terminal to ensure that the code directory is consistent with the terminal working directory. Select the run command according to the programming language (such as Python's python your_file_name.py) to check whether it runs successfully and resolve errors. Use the debugger to improve debugging efficiency.

VS Code can run on Windows 8, but the experience may not be great. First make sure the system has been updated to the latest patch, then download the VS Code installation package that matches the system architecture and install it as prompted. After installation, be aware that some extensions may be incompatible with Windows 8 and need to look for alternative extensions or use newer Windows systems in a virtual machine. Install the necessary extensions to check whether they work properly. Although VS Code is feasible on Windows 8, it is recommended to upgrade to a newer Windows system for a better development experience and security.

VS Code can be used to write Python and provides many features that make it an ideal tool for developing Python applications. It allows users to: install Python extensions to get functions such as code completion, syntax highlighting, and debugging. Use the debugger to track code step by step, find and fix errors. Integrate Git for version control. Use code formatting tools to maintain code consistency. Use the Linting tool to spot potential problems ahead of time.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.

VS Code is available on Mac. It has powerful extensions, Git integration, terminal and debugger, and also offers a wealth of setup options. However, for particularly large projects or highly professional development, VS Code may have performance or functional limitations.

The key to running Jupyter Notebook in VS Code is to ensure that the Python environment is properly configured, understand that the code execution order is consistent with the cell order, and be aware of large files or external libraries that may affect performance. The code completion and debugging functions provided by VS Code can greatly improve coding efficiency and reduce errors.

Golang is more suitable for high concurrency tasks, while Python has more advantages in flexibility. 1.Golang efficiently handles concurrency through goroutine and channel. 2. Python relies on threading and asyncio, which is affected by GIL, but provides multiple concurrency methods. The choice should be based on specific needs.
