qt-blob

Utility library for decoding and encoding Qt QWidget::saveGeometry() and QMainWindow::saveState() binary blobs stored as Base64 strings. Motivated by OBS Studio's global.ini but works with any Qt application.

Requirements

Node.js >= 18

Installation

npm install qt-blob

Example

import * as qt from 'qt-blob';

const geometry = qt.decodeGeometry(base64String);
console.log(geometry.frameGeometry); // { x, y, width, height, ... }

geometry.frameGeometry.x = 100;

const updated = qt.encodeGeometry(geometry);
