  1. Hi everyone, I just released a small LabVIEW tool that allows you to embed custom data into PNG files and extract it back. The image remains fully viewable while carrying hidden data. Optionally, the data can also be exported in XML format. Included VIs: Encode VI – Appends data to a PNG file or exports to XML. Decode VI – Retrieves the embedded data from a PNG file, including XML if used. Key Features: Preserve image appearance while storing hidden data. Optional XML export for structured data. Combine images and related data in a single portable file. Store hidden notes or annotations without affecting the image. Possible Use Cases: Data + Image packaging for measurement results. Metadata storage (experiment details, settings, version info). Lightweight data transport. Scientific experiments or field work with images + sensor readings. Archiving visual and numerical data together. Secure sharing of proprietary information. Dependencies: The tool uses two VIs from the MGI Library (BSD 3-Clause License). For simplicity, these VIs are included directly in the repo. You can check it out and download it here: https://github.com/BitPackTools/pixpack Feedback and suggestions are welcome!
