The entry point for a pipeline that starts from an image rather than a PDF. It wraps the bytes as they are and probes the dimensions, so wrapping a 40 MB scan costs a header read rather than a full decode.

import { Pipeline, DataToImage } from '@stabrise/scaledp'
import { PaddleTextRecognizer } from '@stabrise/scaledp/ocr'

const rows = await new Pipeline([
    new DataToImage(),
    new PaddleTextRecognizer(),
]).transform(pngFile)

imageType is recorded on the output; the bytes pass through unchanged, so declaring 'jpeg' for a PNG mislabels it rather than converting it. resolution is the DPI to record when the row does not already carry one — it is metadata, not a resample.

Zero bytes throw ImageError('Empty image data'), which under the default error contract becomes an Image with that message in exception.
