perform
fun performOcr(imageBytes: ByteArray, mode: String, options: Map<String, String> = emptyMap()): String
Performs OCR directly on the given image bytes, returning a JSON result.
Called by AiProxy for external OCR requests — Tesseract runs in-process (JNI) so there is no HTTP server to forward to, unlike LLAMA or Whisper.
Return
A JSON string with the OCR result.
Parameters
image
The raw image bytes (PNG, JPEG, etc.).
mode
The OCR mode: print, extract, verify, or extract fields.
options
Additional options: pattern, regex_flags, rotate, preprocess, field_patterns.
