需要提前安装cairosvg模块,下载地址http://cairosvg.org/download/
Code:
#! encoding:UTF-8import cairosvgimport osloop = Truewhile loop:svgDir = raw_input("请输入SVG文件目录")if os.path.exists(svgDir) and os.path.isdir(svgDir):loop = Falseelse: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 = Truewhile loop:exportDir = raw_input("请输入导出目录")if os.path.exists(exportDir):loop = Falseelse: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 = Truewhile loops:msg = ""cmd = raw_input("创建 (Y) 重新 (R)")if cmd.upper() == "R":loops = Falseelif cmd.upper() == "Y":os.makedirs(exportDir, True)if os.path.exists(exportDir):loop = Falseloops = Falseelse: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 iloop = Truewhile loop:exportFormat = raw_input("请输入导出类型")if exportFormat.lower() in cate:loop = Falseelse: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 = 0for fileName in files:path = os.path.join(fromDir,fileName)if os.path.isfile(path) and fileName[-3:] == "svg":num += 1fileHandle = 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, " -> " , exportPathprint "已导出 ", num, "个文件"export(svgDir, exportDir, exportFormat)
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
