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)
Copy after login

使用:

复制代码 代码如下:

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
pdf
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

复制代码 代码如下:

D:\>tree svg /F
Folder PATH listing
Volume serial number is 4603-09B2
D:\SVG
    a.svg
    db2.svg
    db3.svg
 
No subfolders exist
 
 
D:\>tree images /F
Folder PATH listing
Volume serial number is 4603-09B2
D:\IMAGES
    a.png
    db2.png
    db3.png
 
No subfolders exist
