Python实现批量把SVG格式转成png、pdf格式的代码分享

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)
