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)
