如何從plist文件中提取png圖像？

-1

我目前有一組plist文件。裏面是PNG圖像，一些文件有很多圖像。我正在使用win64 vista。如何從plist文件中提取png圖像？

我已經找過專門用於此目的的東西，比如FileJuicer，但那隻適用於mac用戶。

我認爲plist文件是屬性列表文件。它們只包含圖像文件名，還是包含實際的圖像數據？如果是後者，它們是如何編碼的，或者什麼程序產生了它們？ – 2011-05-22 07:25:21

http://www1.picturepush.com/photo/a/5700734/img/5700734.png 這個圖像是我認爲是代碼視圖中的一個樣子嗎？ – CAN 2011-05-22 07:38:20

不包含任何像素數據。實際的png文件必須在別的地方。 BTW plist文件可以採用XML格式，因此可以是您發佈的plist文件原始內容的屏幕截圖。 – 2011-05-22 07:43:23

哈哈，這是史蒂夫喬布斯所做的一切。你可以使用ChadBurggraf的庫https://github.com/ChadBurggraf/plists-cs來解析C＃中的plist。但正如評論中所討論的那樣，你想要的文件可能不在plist文件中。

在plist文件的同一目錄中還有一個.dat文件。這會更有意義嗎？而我將如何通過從中提取圖像？ – CAN 2011-05-22 07:58:51

我應該提到.dat文件是11.3 MB – CAN 2011-05-22 08:16:38

我寫了這個劇本解壓png文件在plist文件由TexturePacker

第一打包，請確保您有兩個在同一個目錄下的PNG和的plist文件，在我的情況：freeGifts.plist和freeGifts png格式

其次，下同腳本unpack_plist.py

然後，蟒蛇unpack_plist.py freeGifts，它會產生大量的PNG文件到一個名爲freeGifts

要求：python，PIL

感謝Sean.Z.
爲unpack_plist.py，你需要：
1：PIL已經安裝在你的電腦上。
2：使用python 2.5
python2.5 unpack_plist.py birdfly
否則您將失敗。
----- 2013-07-25--
對於一些旋轉的plist，上面的腳本可能有一些bug。我修改它如下：



#python2.5 unpack_plist.py birdfly

感謝Sean.Z.第一。
但我發現旋轉不好，並且ygweric的補丁不夠好。
，因爲當png包含jpg文件（模式P）時它會失敗。有時透明將成爲黑色背景。
我試圖解決這個問題，我的代碼如下：

 
    #! /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) 
     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_', '')

      gen_png_from_plist(plist_filename, png_filename) 
     else: 
      print "make sure you have boith plist and png files in the same directory"

如果您有JRE在你的電腦，或者您也可以安裝，然後你可以使用我創建解壓的.plist文件的工具。它還支持在LibGdx項目中使用的.pack文件以及用於像unity這樣的許多引擎中的.xml文件來打包紋理。
