Image translate

[FrontEnd07]

Thank you for the open source code, I have a question: can it be translated using an image?

[cjvnjde]

In theory, yes. However, I couldn't find a way to make it work.

Here is the code I tested. It consistently responds with the same image data without any translation.

import https from "node:https";
import fs from 'node:fs';
import path from 'node:path';
import zlib from 'node:zlib';

export function translate(filePath) {
    const imagePath = path.resolve(__dirname, filePath);
    const fileData = fs.readFileSync(imagePath);
    const base64 = Buffer.from(fileData).toString('base64');

    return new Promise((resolve, reject) => {
        let body = encodeURIComponent(`[[["WqWDPb","[[\\"${base64}\\",\\"image/png\\"],\\"en\\",\\"es\\"]",null,"generic"]]]`);
        body = `f.req=${body}&`;

        const searchParams = new URLSearchParams({
            rpcids: "WqWDPb",
            "source-path": "/",
            "bl": "boq_translate-webserver_20240220.05_p0",
            hl: "en-US",
            "soc-app": "1",
            "soc-platform": "1",
            "soc-device": "1",
            rt: "c"
        });

        const url = `https://translate.google.com/_/TranslateWebserverUi/data/batchexecute?${searchParams}`;

        const req = https
            .request(
                url,
                {
                    method: "POST",
                    headers: {
                        "Accept-Encoding": "gzip, deflate, br",
                        "Content-Type": "application/x-www-form-urlencoded;charset=utf-8",
                        "Content-Length": Buffer.byteLength(body),
                    }
                },
                (resp) => {
                    const gunzip = zlib.createGunzip();
                    resp.pipe(gunzip);
                    let data = "";

                    gunzip.on("data", (chunk) => {
                        data += chunk;
                    });

                    gunzip.on("end", () => {
                        resolve(data);
                    });
                },
            )
            .on("error", reject);

        req.write(body);
        req.end();
    });
}

translate("image.png").then((data) => {
    console.log(data)
})

Anyway, did you manage to read the image?

[cjvnjde]

It uses images in base64 encoding.

In this example, the selected text is an image:

@cjvnjde Did you manage to get translated image? I am getting same Image I sent.

[cjvnjde]

no, most likely we need to pass the X-Goog-BatchExecute-Bgr header to be able to translate images. But the algorithm by which it is generated is a mystery

I tried passing it, but same response. Google is good at hiding stuffs, IG. Pls do let me know if you get some luck
