将Texture Packer制作的.pvr.ccz和.plist文件还原为多个原图

1.首先安装python-2.7.6

2.安装PIL-1.1.7（python2.7.6对应的版本）

3.使用Texture Packer工具将.pvr.ccz文件转换为.png文件

4.将以下代码保存为：split.py

#!python
import os,sys
from xml.etree import ElementTree
from PIL import Image

def tree_to_dict(tree):
d = {}
for index, item in enumerate(tree):
if item.tag == 'key':
if tree[index+1].tag == 'string':
d[item.text] = tree[index + 1].text
elif tree[index + 1].tag == 'true':
d[item.text] = True
elif tree[index + 1].tag == 'false':
d[item.text] = False
elif tree[index+1].tag == 'dict':
d[item.text] = tree_to_dict(tree[index+1])
return d

def gen_png_from_plist(plist_filename, png_filename):
file_path = plist_filename.replace('.plist', '')
big_image = Image.open(png_filename)
root = ElementTree.fromstring(open(plist_filename, 'r').read())
plist_dict = tree_to_dict(root[0])
to_list = lambda x: x.replace('{','').replace('}','').split(',')
for k,v in plist_dict['frames'].items():
rectlist = to_list(v['frame'])
width = int( rectlist[3] if v['rotated'] else rectlist[2] )
height = int( rectlist[2] if v['rotated'] else rectlist[3] )
box=( 
int(rectlist[0]),
int(rectlist[1]),
int(rectlist[0]) + width,
int(rectlist[1]) + height,
)
sizelist = [ int(x) for x in to_list(v['sourceSize'])]
rect_on_big = big_image.crop(box)

if v['rotated']:
rect_on_big = rect_on_big.rotate(90)

result_image = Image.new('RGBA', sizelist, (0,0,0,0))
if v['rotated']:
result_box=(
( sizelist[0] - height )/2,
( sizelist[1] - width )/2,
( sizelist[0] + height )/2,
( sizelist[1] + width )/2
)
else:
result_box=(
( sizelist[0] - width )/2,
( sizelist[1] - height )/2,
( sizelist[0] + width )/2,
( sizelist[1] + height )/2
)
result_image.paste(rect_on_big, result_box, mask=0)

if not os.path.isdir(file_path):
os.mkdir(file_path)
outfile = (file_path+'/' + k).replace('gift_', '')
print outfile, "generated"
result_image.save(outfile)

if __name__ == '__main__':
filename = sys.argv[1]
plist_filename = filename + '.plist'
png_filename = filename + '.png'
if (os.path.exists(plist_filename) and os.path.exists(png_filename)):
gen_png_from_plist( plist_filename, png_filename )
else:
print "make sure you have boith plist and png files in the same directory"

4.修改文件名称：

.png文件命名为：aaaaaa.png（和.plist文件名称相同）

.plist文件命名为：aaaaaa.png（和.png文件名称相同）

.py文件命名为：split.py（.py名称随意）

5.将.png和.plist以及.py文件放在同一目录内，运行CMD，进入目录，执行以下命令：

python split.py aaaaaa

注：aaaaaa没有后缀名，名称与.png和.plist相同
