Kivy 从memory 读取image

借助PIL来处理的图片数据

fp = BytesIO()                                                                         
img = Image.frombytes('RGB', img_size, buf_bytes, 'raw', 'BGR;16', 0, 1)               
img.save(fp, 'png')                                                                    
                                                                                               
return fp.getvalue()                 

之后,用kivy.core.image.Image处理数据

               
self.texture = CoreImage(BytesIO(data), ext = 'png').texture
