上述是修改单一的图片,若要批量修改文件夹下的所有图片,则要使用循环,在上面基础添加 例如:
def BFS_Dir(dirPath, dirCallback=None, fileCallback=None):
queue = []
ret = []
queue.append(dirPath);
while len(queue) > 0:
tmp = queue.pop(0)
if os.path.isdir(tmp):
ret.append(tmp)
for item in os.listdir(tmp):
queue.append(os.path.join(tmp, item))
if dirCallback:
dirCallback(tmp)
elif os.path.isfile(tmp):
ret.append(tmp)
if fileCallback:
fileCallback(tmp)
return ret
第一个参数为图片的目录路径,第二个参数是(目录路劲的回掉方法),第三个参数是图片处理回掉方法
