Embed a PDF Viewer in Blazor Applications

  • Responsive UI – pinch‑zoom, rotate, flip, and thumbnail navigation work seamlessly on desktop and mobile browsers.

  • Instant keyword highlighting across scanned PDFs.
  • Fine‑grained filters for page range, confidence score, and annotation type.
  • Search API returns JSON that any front‑end framework can consume.

Secure CAD Rendering in Cloud Environments

Doconut’s CAD pipeline supports DWG, DXF, and other engineering formats:

  • Container‑ready – runs on Docker, Azure Container Instances, or AWS Fargate.
  • Enterprise‑grade security – TLS encryption, role‑based access control, and audit logging.
  • Scalable – horizontal scaling keeps preview times sub‑second, even under heavy load.
