responsiveimage 1.0.0

Create different scaled versions of an image, in webp, jpg, png, svg,... to be used on resposive website

Introduction

responsiveimage is a python package aimed at building responsive version of images.

Supported image format are webp, jpg, png, gif and svg.

Usage

Installation

Run python -m pip install responsiveimage to install the python package.

Also, please install the binaries ffmpeg and optipng (using apt-get, pacman, or directly from sourceforge) to further optimize the png version of the sprite.

Usage

• resize and save all images in <srcdir> into <dstdir>. New size is 1920px by default (at largest dimension, keep the aspect-ratio), and save quality is:
  • gif and svg: direct copy
  • png: use Pillow library, with Optimize=True
  • jpg: quality=80, progressive, 4:2:2
  • webp: quality=80
  • mp4: use ffmpeg to scale at 1024

python -m responsiveimage --src-dir <srcdir> --dst-dir <dstdir>

• --export-to-webp: also export the webp version of the image

• --size <s1,s2...>: different scaling are generating, instead of the default 1920px. In such a case, the created images are suffixed using -size. As an example, using --size 1024,512, an image img.jpg will be rescaled with 1024px and named img-1024.jpg, and another one rescaled at 512px and named img-512.jpg

• --mp4-as-gif: from a mp4 file, the gif and the webp animated versions are created, using ffmpeg
