OCR and rasterization

When Ovrin falls back to OCR, how a page is rasterised first, and why a cloud provider that accepts a PDF needs no local renderer at all.

When a PDF or image lacks a usable text layer, Ovrin can rasterize the page and run OCR or image-based reading. This is where the rendering seam matters.

Why OCR is a fallback

OCR is slower, noisier, and less precise than native text extraction, but it is essential for scanned documents and images.

Renderer seam

The renderer is responsible for turning pages into images suitable for OCR or vision-based interpretation.
