How to Dither JPEG Images and Photos with Python

Enhancing image and photo parameters for a website significantly impacts web traffic. Among these optimizations, reducing an image’s color palette effectively minimizes file sizes and accelerates page loading. Yet, to prevent abrupt edges or disturbances in color gradients, leveraging the dithering method is recommended. This technique aids in refining color transitions and enhancing overall image quality. It introduces a slight “noise” that positively influences image perception. For dither images in the JPEG format, we’ll apply Aspose.Imaging for Python via .NET API which is a feature-rich, powerful and easy to use image manipulation and conversion API for Python platform. You may install it using the following command from your system command.

The system command line

>> pip install aspose-imaging-python-net

Steps to Dither JPEG via Python

You need the aspose-imaging-python-net to try the following workflow in your own environment.

  • load JPEG files with Image.Load method;
  • dither image;
  • save dithered image to disc in the supported by Aspose.Imaging format.

System Requirements

Aspose.Imaging for Python is supported on all major operating systems. Just make sure that you have the following prerequisites.

  • Microsoft Windows / Linux with .NET Core Runtime.
  • Python and PyPi package manager.

  • About Aspose.Imaging for Python API

    Aspose.Imaging API is an image processing solution to create, modify, draw or convert images (photos) within applications. It offers: cross-platform Image processing, including but not limited to conversions between various image formats (including uniform multi-page or multi-frame image processing), modifications such as drawing, working with graphic primitives, transformations (resize, crop, flip&rotate, binarization, grayscale, adjust), advanced image manipulation features (filtering, dithering, masking, deskewing), and memory optimization strategies. It’s a standalone library and does not depend on any software for image operations. One can easily add high-performance image conversion features with native APIs within projects. These are 100% private on-premise APIs and images are processed at your servers.

    JPEG What is JPEG File Format

    A JPEG is a type of image format that is saved using the method of lossy compression. The output image, as result of compression, is a trade-off between storage size and image quality. Users can adjust the compression level to achieve the desired quality level while at the same time reduce the storage size. Image quality is negligibly affected if 10:1 compression is applied to the image. The higher the compression value, the higher the degradation in image quality.
