public static String getOCRJsonFromImage (PDFDoc dst, String src, OCROptions options)
Perform OCR on an image and return resulting JSON string. Side effect: source image is converted to PDF and stored in the destination document. The box is a summary for a text fragment bounding box (leftmost x, bottommost y, width, height) The box coordinates are in units of points (1/72 of an inch), with the origin at the top left, and larger x and y coordinates representing further right and down, respectively
Parameters
| dst | -- The destination document |
|---|---|
| src | -- The path to the input image |
| options | -- OCR options (optional) |
Returns
- JSON string representing OCR results
Throws
| PDFNetException |
