如何从 plist 文件中提取 png 图像？

Question

我目前有一组 plist 文件。里面是png图片，有些文件有很多图片。我用的是win64 vista。

我已经寻找了专门为此目的的东西，例如 FileJuicer，但这仅适用于 mac 用户。

Answer 1

我编写了此脚本来解压 TexturePacker

首先，确保 png 和 plist 文件都在同一目录中，在我的例子中： freeGifts.plist 和 freeGifts.png

其次，与 unpack_plist.py 相同的以下脚本

然后， python unpack_plist .py freeGifts，它会生成很多png文件到名为freeGifts的目录

要求：python，PIL

#! /usr/lical/bin/python
import os,Image,sys
from xml.etree import ElementTree

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)
        result_image = Image.new('RGBA', sizelist, (0,0,0,0))
        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 v['rotated']:
            result_image = result_image.rotate(90)
        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"

哈哈，这都是史蒂夫·乔布斯所做的。您可以使用 ChadBurggraf 的库在 C# 中解析 plist https://github.com/ChadBurggraf/plists-cs。但正如评论中所讨论的，您想要的文件可能不在 plist 文件中。

感谢肖恩·Z。首先。
但我发现rotate不好，而且ygweric的patch也不够好。
因为当 png 包含 jpg 文件（模式 P）时，它会失败。有时透明会变成黑色背景。
我尝试修复此问题和我的代码如下：

    #! /usr/lical/bin/python
    import os,Image,sys
    from xml.etree import ElementTree

    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)

        plist_dict = tree_to_dict(root[0])

        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=(

            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=(

                    )

感谢 Sean.Z。
对于 unpack_plist.py，您需要：
1: PIL已安装在您的电脑上。
2：使用python 2.5
python2.5 unpack_plist.py Birdfly

否则你会失败。
-----2013-07-25--
对于一些旋转的plist，上面的脚本可能有一些错误。我将其修改如下：

如果您的 PC 中有 JRE 或者您可能已经安装了 JRE，那么您可以使用我创建的工具来解压 .plist 文件。它还支持 LibGdx 项目中使用的 .pack 文件和 Unity 等许多引擎中使用的 .xml 文件来打包纹理。
