qt-webp-plugin

March 3, 2016 ยท View on GitHub

Enables Qt4 and Qt5 applications to load and save images in the WebP image format.

NOTICE Since version 5.3, Qt is bundled with a WebP plugin. You might need to install the qt5-imageformats package (or similar) to get it. See https://github.com/ArchangelSDY/qwebpa for a fork with animation support. For Qt 4, you would still need this or https://github.com/stevenyao/webp .

Features

  • Reading WebP images
  • Writing Lossless WebP images when Quality == 100
  • Writing Lossy WebP images when Quality <= 99. Quality is passed to libwebp in the range 1 to 100.

Installation

After successful compilation you should have a webp.* file (extension dependent on OS). You can install this globally or application specific. To install it globally, copy it to QTDIR/plugins/imageformats/. To only use it with a specific application, create a folder called imageformats in the executable's folder and place the plug-in there.
