Kivy在更改Image.texture后，给出黑色效果

我的代码：

self.ids['profimage'].source = './add_photo.png'
几行之后

pimg = Image.open(bio).convert('RGB') # bio is a valid _io.BytesIO object with image data
pimg = pimg.crop((0, 0, int(self.width*0.3), int(self.width*0.3)))
pimg.save(data, format='png')
data.seek(0)
im = CoreImage(BytesIO(data.read()), ext='png')
self.ids['profimage'].texture = im.texture

在改变纹理之前^

改变纹理后^

有人能帮我吗
