Hi,

Here's a simple example of how you can integrate image compression with a button click action in an Odoo model:


from odoo import models, fields, api

from PIL import Image

import io

import base64


class MyModel(models.Model):

    _name = 'my.model'


    name = fields.Char(string="Name")

    image = fields.Binary(string="Image")


    @api.multi

    def compress_image(self):

        for record in self:

            try:

                img = Image.open(io.BytesIO(base64.b64decode(record.image)))

                output_stream = io.BytesIO()


                # Compress the image with the specified quality (adjust as needed)

                img.save(output_stream, format='JPEG', quality=85)


                # Update the image field with the compressed image

                record.image = base64.b64encode(output_stream.getvalue())

                output_stream.close()


                print("Image compression successful!")

            except Exception as e:

                print(f"An error occurred: {e}")


Make sure to adjust the code according to your specific requirements and the structure of your Odoo module. Additionally, handle error cases and edge scenarios appropriately.


Hope it helps
