0.1.0

hdr-canvas 0.1.0

Introduction

Since the last release many areas of handling HDR contet in the browser have evolved.
Most notably is certainly the introduction of the Float16Array in the ImageData construtor:

• The WhatWG spec, MDN and [BCD](new ImageData(new Float16Array(4), 1, 1, {pixelFormat:"rgba-float16"})) have been updated accordingly. You can test your own browser using new ImageData(new Float16Array(4), 1, 1, {pixelFormat:"rgba-float16"}).
  • Still open in Firefox
  • Hidden behind flag in Safari
  • Chromium has implemented it starting with 137: **The ImageData constructor only acceppts Float16Array instead of Uint16Array. This makes older versions of this modue obsolute, since they targeted the chromium specific solution.
  • If Safari enables it by default it will be also in the Typescript DOM types

As @reitowo pointed out, there has been a change to the getContext("2d") method. The key pixelFormat has been replaced by colorType.

In parallel threre have been changes to the UltraHDR image format, especially te encoding of gain map matadata. While this used to be don in XMP it's now done according to ISO 21496-1. This ihas been adopted by Google and Apple in newer OS versions like Android 15 and iOS 18 to avoid cross-platform fragmentation. The UltraHDR Library has already changed to ussin the ISO format as default.

Currently the ThreeJS UHDR loader doesn't know how to handle this change, see mrdoob/three.js#32293.

Key Changes & New Features

• Better support for official Web-APIs
  • Use Float16Array instead of Uint16Array
  • Use the correct option for initializing 2D canvas context

Improved Documentation

The documentation have been greatly improved, there is now also a site including the examples and API docs.

Examples

The examples fro the blog are now part of this repository:

• tests/site/assets/ts/hdr-three.js.ts - Three JS with HDR texture
• tests/site/assets/ts/image-slider.ts - Generated HDR content
• tests/site/assets/ts/main.ts - feature detection

These example are also avalable on the new documentation site

Advocacy

Since the changes by the WhatWG weren't picked up already there had to be some Issues in the relevant repos to be raised.
