Get image metadata (dimensions, format, orientation, size, alpha, density).

Draw multiple annotations (bbox, arrow, highlight, callout, text, circle) on an image. Returns annotated image + manifest JSON.

Draw a single bounding box on an image. Convenience wrapper around annotate.

Highlight a rectangular region on an image. Convenience wrapper around annotate.

Draw numbered callout circles on an image. Convenience wrapper around annotate.

Detect 1D barcodes (EAN, UPC, Code 128/39, etc.) and 2D codes (QR, DataMatrix, PDF417) in an image. Returns deterministic pixel bounding boxes for each detected code. Requires pyzbar + zbar library.

Detect text regions in an image using Tesseract OCR. Returns each region with its text content, pixel bounding box, and confidence score. Use this to find the coordinates of brand titles, dosage tables, ingredients lists, etc. Supports multiple languages (e.g. eng+rus) and various preprocessing modes for photos vs. clean scans. Set filter_garbage=false to keep OCR-noise regions, or crop_regions=true to also save per-region image crops that a vision model can re-recognize (useful when tesseract quality is low).

Crop a region of an image and save it to a new file. Useful for iteratively zooming into a region so a vision model can give more precise coordinates. Bounding box can be in pixel or normalized [0, 1] coordinates; optional padding expands the crop on each side.
