JS image decode
|
|
===============
|
|
|
|
Background
|
|
----------
|
|
|
|
It is currently cumbersome to go from an encoded Blob or ArrayBuffer of image bytes to
|
|
an ImageData (Uint8ClampedArray) for further image processing.
|
|
See current/index.html for an example where a user can select an image from disk
|
|
and have JS turn it into a grayscale version (no backend server).
|
|
|
|
|
|
Proposal
|
|
--------
|
|
We propose... See proposed/index.html for an API that makes this much cleaner.
|
|
It uses the CanvasKit WASM library under the hood to provide functionality, but
|
|
the intent is for Web Browsers to support this natively. |
