前言

因為學習需要制作遊戲，經常會在網上尋找一些資源進行學習，而一般資源分積分下載下傳源資源或者線上扒取别人的圖集資源。是以很多時候需要對一張合集圖進行拆分，今天主要講解有描述檔案的圖集拆分。

我常接觸的圖集格式一般是

CocosCreator TexturePacker .plst 格式的圖集

LayaBox .json ,atlas引擎自帶貼圖合集格式

Egret 引擎的.json圖集格式

一、為什麼需要圖集打包？

做過遊戲開發的童靴都知道紋理打包，用于下載下傳節約流量減少io操作。也能讓渲染合批提升性能。市面上常用打包工具TexturePacker,還有一些引擎自帶圖集打包的工具。

二、使用python批量拆解plist格式檔案

1.引入庫

代碼如下（示例）：

Python庫主要依賴PIL下Image模闆對圖檔的操作

import os,sys
from xml.etree import ElementTree
from PIL import Image
reload(sys)  
sys.setdefaultencoding('utf8')

2.具體實作代碼

代碼如下（示例）：

#!python
# coding: utf-8
import os,sys
from xml.etree import ElementTree
from PIL import Image
reload(sys)  
sys.setdefaultencoding('utf8')

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 == 'integer':
				d[item.text] = int(tree[index + 1].text) 
            elif tree[index+1].tag == 'dict':
                d[item.text] = tree_to_dict(tree[index+1])

    return d 
	
def read_rect(dict):
	return [dict['x'],dict['y'],dict['width'],dict['height']];
	
    
def gen_png_from_plist(filename, outPath):
	plist_filename = filename + '.plist'
	png_filename = filename + '.png' 
	
	if checkPath(plist_filename) == False or checkPath(png_filename) ==False:
		print("don't find %s png  or plist"%filename)
		return
	
	#擷取大圖
	big_image = Image.open(png_filename)
	
	#讀取plist
	root = ElementTree.fromstring(open(plist_filename, 'r').read())
	plist_dict = tree_to_dict(root[0])
	to_list = lambda x: x.replace('{','').replace('}','').split(',')
	to_int = lambda x:int(x)
	
	for k,v in plist_dict['frames'].items():
		if v.has_key('textureRect'):
			textureRect = to_list(v['textureRect'])
		elif v.has_key('frame'):
			textureRect = to_list(v['frame'])
		else:
			textureRect = read_rect(v)
		
		#獲得圖像尺寸
		if v.has_key('spriteSize'):
			spriteSize = v['spriteSize']
		elif v.has_key('sourceSize'):
			spriteSize = v['sourceSize']
		elif v.has_key('spriteSourceSize'):
			spriteSize = v['spriteSourceSize']
		elif v.has_key("width"):
			spriteSize = str(v['width']) + ',' +  str(v['height'])
			
		spriteSize = to_list(spriteSize)
		spriteSize = map(to_int, spriteSize) 
		result_box = textureRect
		
		#防止寬高小于0導緻錯誤
		if spriteSize[0] <= 0 or spriteSize[1]<0 :
			print "< 0"
			continue
		result_image = Image.new('RGBA', spriteSize, (0,0,0,0))
	 
		if (v.has_key('textureRotated') and v['textureRotated']) or (v.has_key('rotated') and v['rotated']): 
			result_box[0] = int(textureRect[0])
			result_box[1] = int(textureRect[1])
			result_box[2] = int(textureRect[0] + spriteSize[1])
			result_box[3] = int(textureRect[1] + spriteSize[0])
		else:
			result_box[0] = int(textureRect[0])
			result_box[1] = int(textureRect[1])
			result_box[2] = int(textureRect[0] + spriteSize[0])
			result_box[3] = int(textureRect[1] + spriteSize[1])

		
		#獲得小圖
		rect_on_big = big_image.crop(result_box)
		# 有旋轉
		if (v.has_key('textureRotated') and v['textureRotated']) or (v.has_key('rotated') and v['rotated']):
			rect_on_big = rect_on_big.transpose(Image.ROTATE_90)
			
		result_image.paste(rect_on_big) 
		
		 
		if not os.path.isdir(outPath):
			os.mkdir(outPath)
		k = k.replace('/', '_')
		outfile = (outPath+'/' + k).replace('gift_', '')
		#print k
		if outfile.find('.png') == -1:
			outfile = outfile + '.png'
		print outfile, "generated"
		result_image.save(outfile)


def read_dir( path, outPath):
	for name in os.listdir( path ): 
		if os.path.isdir( os.path.join(path, name) ): 
			find_file(os.path.join(path, name),outPath )
		else:
			portion = os.path.splitext(name)
			if portion[1] == '.plist':
				fileName = os.path.join(path, portion[0])
				outDir = os.path.join(outPath, portion[0]); 
				gen_png_from_plist(fileName , outDir)
				
def checkPath(path):
	if not os.path.exists( path ):
		print "not find 1 %s"%path
		return False
	return True


if __name__ == '__main__': 
	if len( sys.argv ) < 2:
		dirName = raw_input("Enter your DirName: ")
	else:
		dirName = sys.argv[1]
		
	if len( sys.argv ) < 3:
		outPath = raw_input("Enter your outPath: ")
	else:
		outPath = sys.argv[2]
	
	 
	outPath = os.path.join( os.getcwd(), outPath )
	if not os.path.isdir( outPath ):
		os.mkdir( outPath )
	
	path =  os.path.join(os.getcwd(),dirName)
	if checkPath(path): 
		read_dir(path,outPath)

三、使用python批量拆解laya引擎圖集檔案 

# coding: utf-8
import os
import sys
import json
import time
from PIL import Image

def checkPath(path):
	if not os.path.exists( path ):
		print "not find 1 %s"%path
		return False
	return True


def splitImage(path, fileName, outPath ):
	# 檢查JSON檔案 
	jsonPath = os.path.join(path, "%s.json"%fileName  )
	if not os.path.exists( jsonPath ):
		jsonPath = os.path.join( path, "%s.atlas"%(fileName ))
		if not os.path.exists( jsonPath ):
			print "not find 0 {}".format(jsonPath)
			return
	
	# 檢查PNG檔案 
	pngPath = os.path.join( path, "%s.png"%fileName )
	if checkPath(pngPath) == False:
		return
	
	# 檢查輸出目錄
	outPath = os.path.join( path, outPath )
	if not os.path.isdir( outPath ):
		os.mkdir( outPath )
		
	# 取JSON檔案
	f = open( jsonPath, 'r' )
	fileStr = f.read()
	f.close()
	jsonData = json.loads( fileStr ) 
	
	#檢查image集合
	meta = jsonData.get( "meta" )
	imageStr = meta.get( "image" )
	
	#拆分檔案名
	images = imageStr.split(",") 
	
	#拆分檔案名
	images = imageStr.split(",") 
	
	imgList = []
	
	#打開多個檔案準備切割
	for img in images: 
		pngPath = os.path.join( path, img ) 
		pngPath = pngPath.replace("~","-")
		if not os.path.exists( pngPath ):
			print "not find 2 %s"%pngPath 
			break;
		imgList.append(Image.open( pngPath, 'r' ))
	
	# 開始切圖
	lastIdx = 0
	frames = jsonData.get( "frames" )
	for fn in frames.keys():
		data = frames.get( fn )
		frame = data.get( "frame" )
		idx = frame.get( "idx" ) 
		x = frame.get("x")
		y = frame.get("y")
		w = frame.get("w")
		h = frame.get("h")
		box = ( x, y, x+w, y+h )
		outFile = os.path.join( outPath, fn )
		imgData = imgList[idx].crop( box )
		imgData.save( outFile, 'png' )

#讀取指定目錄	 
def find_file( path, outPath):
	for name in os.listdir( path ): 
		if os.path.isdir( os.path.join(path, name) ): 
			find_file(os.path.join(path, name),outPath )
		else:
			portion = os.path.splitext(name)
			if portion[1] == '.atlas' or portion[1] == '.json': 
				fileName = os.path.join(path, portion[0])
				outDir = os.path.join(outPath, portion[0]); 
				splitImage(path,fileName , outDir)
				


if __name__=='__main__':
	# 取得參數
	if len( sys.argv ) < 2:
		target = raw_input("Enter your DirName: ")
	else:
		target = sys.argv[1]
	if len( sys.argv ) < 3:
		outPath = raw_input("Enter your outPath: ")
	else:
		outPath = sys.argv[2]

	outPath = os.path.join( os.getcwd(), outPath )
	if not os.path.isdir( outPath ):
		os.mkdir( outPath )

	path =  os.path.join(os.getcwd(),target)
	if checkPath(path): 
		find_file(path,outPath)

四、使用python批量拆解Egret引擎圖集檔案 

# coding: utf-8
import sys
reload(sys)
sys.setdefaultencoding('utf8')
import os 
import json
import time
from PIL import Image

def checkPath(path):
	if not os.path.exists( path ):
		print "not find 1 %s"%path
		return False
	return True


def splitImage(path, fileName, outPath ):
	# 檢查JSON檔案 
	jsonPath = os.path.join( path, "%s.json"%fileName  ) 
	if not os.path.exists( jsonPath ):
		print "not find %s"%jsonPath
		return
	
	# 檢查PNG檔案 
	pngPath = os.path.join( path,  "%s.png"%fileName ) 
	if not os.path.exists( pngPath ):
		print "not find %s"%pngPath
		return

	# 檢查輸出目錄 
	if not os.path.isdir( outPath ):
		os.mkdir( outPath )
		

	# 取JSON檔案
	f = open( jsonPath, 'r' )
	fileStr = f.read()
	f.close()
	jsonData = json.loads( fileStr ) 
	
	#檢查image集合
	imgList = []
	imageStr = jsonData.get( "file" )
	img = Image.open(os.path.join(path,imageStr),'r')
	imgList.append(img)
	
	# 開始切圖
	frames = jsonData.get( "frames" )
	for fn in frames.keys():
		data = frames.get( fn )  
		x = data.get("x")
		y = data.get("y")
		w = data.get("w")
		h = data.get("h")
		box = ( x, y, x+w, y+h )
		outFile = os.path.join( outPath, fn )
		imgData = imgList[0].crop( box )
		# if imgData.mode == "P":
		# 	imgData = imgData.convert('RGB')
		outFile = outFile + ".png"
		imgData.save( outFile )
	 
#讀取指定目錄	 
def find_file( path, outPath):
	for name in os.listdir( path ): 
		if os.path.isdir( os.path.join(path, name) ): 
			find_file(os.path.join(path, name),outPath )
		else:
			portion = os.path.splitext(name)
			if portion[1] == '.json': 
				fileName = portion[0]
				outDir = os.path.join(outPath, portion[0]);  
				splitImage( path ,fileName, outDir )
	
if __name__=='__main__':
	# 取得參數
	if len( sys.argv ) < 2:
		dirName = raw_input("Enter your dirName: ")
	else:
		dirName = sys.argv[1]
	if len( sys.argv ) < 3:
		outPath = raw_input("Enter your outPath: ")
	else:
		outPath = sys.argv[2]
	
	outPath = os.path.join( os.getcwd(), outPath )
	if not os.path.isdir( outPath ):
		os.mkdir( outPath )

	path =  os.path.join(os.getcwd(),dirName) 
	if checkPath(path): 
		# 開始切圖
		find_file(path, outPath)
