html2canvas-oklch v1.5.0-alpha.0

html2canvas-oklch

JavaScript HTML renderer

html2canvas-oklch is a fork of html2canvas that allows you to take "screenshots" of webpages (or parts thereof) directly in the user's browser. In addition to the original features, this fork adds support for the OKLCH color function.

How does it work?

The script renders the current page as a canvas image, by reading the DOM and the different styles applied to the elements.

It does not require any rendering from the server, as the whole image is created on the client's browser. However, as it is heavily dependent on the browser, this library is not suitable to be used in nodejs. It doesn't magically circumvent any browser content policy restrictions either, so rendering cross-origin content will require a proxy to get the content to the same origin.

The script is still in a very experimental state, so I don't recommend using it in a production environment nor start building applications with it yet, as there will be still major changes made.

• OKLCH Support: This fork adds support for OKLCH color values, ensuring compatibility with Tailwind CSS 4 and other modern styling techniques.

Browser compatibility

The library should work fine on the following browsers (with Promise polyfill):

• Firefox 3.5+
• Google Chrome
• Opera 12+
• IE9+
• Safari 6+

As each CSS property needs to be manually built to be supported, there are a number of properties that are not yet supported.
