IWB Viewer

The IWB Viewer renders exported interactive whiteboard content for review, verification, and archiving. It reconstructs frames, slides, and layered elements from common IWB export bundles, preserving layout fidelity and media embedding. The tool operates on input files (export bundles, PDFs, or images), builds an in-memory scene graph, and provides a faithful preview suitable for validation before deployment. It enables educators and administrators to verify sequencing, annotations, and embedded media without installing full IWB software, supporting offline workflows and streamlined content sharing. Conceptually, it decouples export formats from classroom run-time by normalizing frame order, scale, and layering, enabling consistent previews across devices. The unique value lies in fast, portable previews that maintain fidelity to original interactive content, along with metadata extraction (frame count, dimensions, timestamps) for cataloging. Core features include format detection, multi-file bundle handling, frame rendering, viewport transformation, and optional preview export to image or PDF. Use cases span lesson preparation, quality assurance for district materials, and educator content curation, where rapid verification and easy distribution are key. The tool is deliberately read-only with respect to source content to avoid accidental modification; it favors performance, local processing, and secure sharing of previews.
