Convert Color Image to Black and White using Python REST API

This short guide explains how to convert color image to black and white using Python REST API. You will learn to develop a color picture to black and white converter using Python REST Interface with a Python-based Cloud SDK. It will guide you through uploading images to the Cloud storage and changing the color to Black and White.

Prerequisite

Steps to Convert an Image to Black and White using Python RESTful Service

  1. Setup ImagingApi credentials by providing the Cloud endpoint, client ID, and secret
  2. Read the input image from the local file system into a memory stream
  3. Upload the local image to the Cloud storage so it can be processed remotely
  4. Once the image is uploaded, create a grayscale image request using the filename
  5. Send the request to the server using the GrayscaleImage() method and fetch the returned grayscale as a stream
  6. Save the grayscale image locally with a new filename

These steps define the process to convert image to grayscale using Python REST Interface. Commence the process by setting up the API credentials, reading the input image from the local file system, uploading the image to the Cloud storage, creating the grayscale image request, and sending the request to the server. Once the call is successful, it will return the resultant image in a stream.

Code to Convert Picture to White and Black using Python Low Code API

This code has demonstrated the process for converting an image to grayscale using Python-based API. You can also use this feature without Cloud storage. It is also possible to save the output in different file formats if required.

This article has taught us to change colored pictures to black and white. To crop images, refer to the article on Crop Image with Python REST API.
