Document Scanner SDKPxBundledOcrData Class
@interface PxBundledOcrData : NSObject
Resolves the directory of OCR data that ships bundled inside the SDK, so text-orientation detection works offline on a fresh install with no network download.
Overview
The SDK bundles the Tesseract OSD (orientation and script detection) model in encrypted form. On first use it is decrypted into a writable directory owned by the SDK; the resolver returns that directory, which can be passed straight to PxTextDetector’s initialiser. Subsequent calls return the cached directory without re-decrypting.
The first-run decrypt processes ~10 MB and must not run on the main thread — use osdDirectoryWithCompletion: from UI code, or call osdDirectoryWithError: from a background thread.
Type Methods
| Name | Summary |
|---|---|
| osdDirectoryWithCompletion: | Resolves the directory containing the bundled OSD data, decrypting it on first use off the main thread. The completion runs on an arbitrary queue. |
| osdDirectoryWithError: | Resolves the directory containing the bundled OSD data (osd.traineddata), decrypting it on first use. Synchronous. |
