++ How to recolor icons for doc.qt.io
++ ==================================
++
++ You can view Qt Documentation online at https://doc.qt.io in dark and light
++ modes. To make the icons you use in the docs visible in both modes, save icon
++ files as gray-scale images with a transparent background.
++
++ If you receive a large number of icons that are not visible in either light
++ or dark mode or have a solid background, run the ``recolordocsicons.py``
++ Python script.
++
++ The script runs ImageMagick to recolor the images and optipng to optimize the
++ icon files.
++
++ ## Preparation
++
++ To run the script, you will need to install the following tools and add them
++ to the PATH:
++
++ - Python 3.x (the script has been tested to work with 3.10)
++ - ImageMagick
++ - optipng
++
++ ## Running the script
++
++ Use the `-docspath` option to specify the path to the folder where you stored
++ the icons.
++
++ For example, if you saved the new icons in `C:\iconconversions`, switch to
++ the `qttools\util\recolordocsicons` folder and enter:
++
++ `recolordocsicons.py -docspath C:\iconconversions`
