I needed a zoomable image view in SwiftUI that allows user to pan and zoom the image with useful constraints like:

• snap back zoom in beyond 3x
• snap back zoom out beyond entire image is visible
• snap back pan beyond image bounds.

TODO:

• Add rotation support

function randomNoise(canvas, x, y, width, height, alpha) {
    x = x || 0;
    y = y || 0;
    width = width || canvas.width;
    height = height || canvas.height;
    alpha = alpha || 255;
    var g = canvas.getContext("2d"),

Error: Only plain objects, and a few built-ins, can be passed to Client Components from Server Components.
Classes or null prototypes are not supported.

When above error is thrown in React 14+, root cause may be QueryClientProvider not being defined in client scope using "use client".

While this note is useful for achieving compatibility with non-node.js crypto code, it contains implementation details which maybe outdated in the near future. Beware.

key argument

key arguments are expected to be binary strings which is bytes packed as chararacter codes of a string.

What this means is that only lower byte of each character will be used.
