“简单的笔记”
最近在工程中需要去裁剪一些图集，所以写了一个根据xml数据裁剪图集的小脚本。
基本思路
- 使用Python的PIL库打开图集；
- 解析Xml配置表获取图片的像素位置与大小，调用Crop()进行裁剪；
附上脚本
from PIL import Image
import os
from xml.dom.minidom import parse
import xml.dom.minidom as xmldom
#图集路径与配置表路径
imgPath = "./TroopCardAll.png"
xmlPath = "./TroopCardAll.xml"
# 使用PIL打开图像
img = Image.open(imgPath)
# 使用minidom解析器打开 XML 文档
DOMTree = xmldom.parse(xmlPath)
# 获取子节点
collection = DOMTree.documentElement
print("DocumentElement:", collection)
# 子节点的签名为 SubTexture
subTextures = collection.getElementsByTagName("SubTexture")
print("getElementsByTagName:", type(subTextures))
print(len(subTextures))
# 遍历子节点并切图
for subTexture in subTextures:
name = subTexture.getAttribute("name")
x = int(subTexture.getAttribute("x"))
y = int(subTexture.getAttribute("y"))
w = int(subTexture.getAttribute("width"))
h = int(subTexture.getAttribute("height"))
print("name:", name, "x:", x, "y:", y, "w:", w, "h:", h)
subImg = img.crop((x, y, x+w, y+h))
filename = ("./TroopCardAll/" + name + ".png")
print(filename)
# 确认是否有子路经并存储
if "/" in name:
dir = name.rfind("/")
fileDir = "./TroopCardAll/" + name[0:dir]
if not (os.path.exists(fileDir)):
os.makedirs(fileDir)
print("CreateDir:", fileDir)
# 存储图片
subImg.save(filename)
print("Done")
