如何仅使用xml代码在odoo中调整二进制(64)图像的大小？(最大高度)

<field name="image" widget="image" options='{"size": [200, 200]}'/>

from PIL import Image
import io

# 获取二进制图像数据
image_data = self.image

# 将二进制数据转换为Image对象
image = Image.open(io.BytesIO(image_data))

# 调整图像大小
max_height = 200
height_percent = (max_height / float(image.size[1]))
new_width = int((float(image.size[0]) * float(height_percent)))
new_size = (new_width, max_height)
resized_image = image.resize(new_size, Image.ANTIALIAS)

# 将调整后的图像保存回二进制字段
buffer = io.BytesIO()
resized_image.save(buffer, format="PNG")
self.image = buffer.getvalue()
