A simple library to get ImageData on Node.js and browsers

import path from "node:path";

export async function getImageDataWithSharp(inputData, longPathFix = true) {
    if (!sharpCache) {
        const sharpModule = await import("sharp");

    }
    if (longPathFix && typeof inputData === "string") {
        inputData = path.toNamespacedPath(inputData);
    }
    else if (ArrayBuffer.isView(inputData)) {
        inputData = inputData.buffer;
    }
    const sharp = sharpCache;
    const imageData = await sharp(inputData)
        .ensureAlpha()
        .raw()
        .toBuffer({ resolveWithObject: true });
    const { data, info } = imageData;
    return {
        width: info.width,
        height: info.height,
        data: new Uint8ClampedArray(data),
        colorSpace: "srgb",
