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.
