atlas解包求助

有没有支持非预乘alpha的批量解包atlas工具,找遍github只有利用spine的命令行的,不支持非预乘alpha

from pathlib import Path
from typing import Literal
from SpineAtlas import ReadAtlasFile

def batch(fp: str = '', mode: Literal['Normal', 'Premul', 'NonPremul'] = 'Normal', scale: bool = True, subfolder: bool = True):
    path = Path(fp) if fp else Path.cwd()
    need = [i for i in (path.rglob('*.atlas') if subfolder else path.glob('*.atlas')) if i.is_file()]
    for i in need:
        try:
            atlas = ReadAtlasFile(i)
        except:
            print(f'读取Atlas错误 --- {i.as_posix()}')
            continue
        if scale:
            atlas.ReScale()
        atlas.SaveFrames(i.parent.joinpath(i.stem), mode=mode)

if __name__ == '__main__':
    path = r'' # atlas在pc上的路径
    mode = 'Normal' # ['Normal', 'Premul', 'NonPremul'] Normal - 不做任何处理, Premul - 将贴图转换为预乘, NonPremul - 将贴图转换为非预乘
    scale = True # 当贴图尺寸与atlas记录的贴图尺寸不符合时 重新计算帧的范围
    subfolder = True # 是否查找子文件夹内的atlas
    batch(path, mode, scale, subfolder)

试试这个库 https://pypi.org/project/SpineAtlas/
