Can save Plotly image to Cloudinary?

Question

Is it possible to write a Plotly chart directly into Cloudanary without first saving to a file?

So Plotly is something like this.

fig.write_image("fig1.png")

I want to upload the fig straight into Cloudinary. Which is something like this.

cloudinary.uploader.upload("dog.mp4",
                   asset_folder="pets",
                   public_id="my_dog",
                   overwrite=True)

can the fig.write_image() go inside the uploader?

Possible? Not possible. Trying to skip writing it to disk due to permission issues.

Thanks.

All depends on if both functions allow to use file-like object instead of filename.
It could allow to use io.Bytes() to create file in memory instead of file on disk.

I didn't test it but documentation for Plotly write_image() suggests it can use writeable object instead of filename and it could allow to use file-like object

Something similar to:

import io

file_object = io.BytesIO()

fig.write_image(file_object, format='png')

Documentation for upload() shows that it can use data_stream (byte array buffer)
which can be file-like object

file_object.seek(0)  # move to the beginning of file after writing ,
                     # to read from the beginning of data

cloudinary.uploader.upload(file_object, ...)

The same documentation also shows that it can send data converted to string base64 and it also could be used for this - but it would need more work.

It would need to use io.BytesIO to write image in memory, and later read it as bytes file_object.getvaule() and convert to base64 using Python module base64.b64encode()

import io
import base64

file_object = io.BytesIO()

fig.write_image(file_object)

#file_object.seek(0)
#data_bytes = file_object.read()

data_bytes = file_object.getvalue()  # it gets bytes from object without using `.seek()` and `.read()`

data_base64 = base64.b64encode(data_bytes)

text_base64 = data_base64.encode()

text = "data:image/png;base64," + text_base64

cloudinary.uploader.upload(text, ...)
