Use Python for JP2 Images Dithering

Create Python Apps to Dither JP2 Images and Photos via Server APIs

How to Dither JP2 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 JP2 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 JP2 via Python

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

  • load JP2 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.

    JP2 What is JP2 File Format

    JPEG 2000 (JP2) is an image coding system and state-of-the-art image compression standard. Designed, using wavelet technology JPEG 2000 can code lossless content in any quality at once. Moreover, without any substantial penalty in coding efficiency, JPEG 2000 have the capability to access and decode the same content efficaciously into a variety of other resolutions and qualities. The code streams in JPEG 2000 is significantly scalable having regions of interest that provide the facility for spatial random access. Possessing Up to 16384 diverse components with the dimensions in terapixels, and precision that can be high as 38 bits/sample.
