HTML Canvas API - research

@Jarda

const imageData = new ImageData(pixels, WIDTH, HEIGHT);
ctx.putImageData(imageData, 0, 0);

second this. I do not understand what is the problem to allow this, when it was readily available in CEP. Like 4 years of UXP development, and we still do not have basic features, available in any browser.

I just found this topic and I have a question / feedback about the Canvas API, I posted a new topic here:

Missing methods for the canvas API (`.save()` / `.restore()`)

Hello I have an issue with canvas when writing a plugin for Photoshop 2024 - 25.11.0 Release. For context Paper.js is a very powerful library that uses the canvas APIs, see examples of what can be done with Paper.js: Paper.js — Examples My problem is that the CanvasRenderingContext2D object is missing the save() and .restore() methods. This line: github dot com/paperjs/paper.js/blob/92775f5279c05fb7f0a743e9e7fa02cd40ec1e70/src/canvas/CanvasProvider.js#L49 throws when loading Paper.js …

Let me know what you think about that in that new topic

WebGl would be even more useful, because canvas API from web is pretty slow if we want to draw many objects (while WebGl could use GPU acceleration)

Apparently due to resource savings, the CSS property “opacity” still hasn’t been added. And as for WebGL - that’s from a fantasy world with unicorns

WebGL is supported in webview though, it is enough
