Features

Image by Wikipedia

• Write OCR text into Note attributes, which is easy to search
• Skip writing OCR text if Note already exists
• OCR is provided by Cloud Vision API, which supports many languages

Prerequisites

• Google Cloud Platform (GCP) credential for calling Cloud Vision API
• node (pnpm is preffered)

Usage

Set up GCP credential, then type

pnpm install
pnpm run ocr <Images.library path>

Then, Force Realod Library in Eagle. You can search images with OCR result.

Considerations

• Approximately $1.5 per 1,000 images. If you want to filter some images out, modify code.
• Currently, there is no special deal with break lines. Removing BRs has pros/cons, so this topic is debatable.
