Convert PDF with HOCR to PDF/A-3B

Hi,
We are trying to convert a PDF with custom HOCR information to PDF/A-3B.
When searching in the result PDF, the positioning of the cursor is wrong.

Our code:

    public void convert(InputStream inputPdf, OutputStream outputPdf, Optional<String> hocr) {
        Document pdfDoc = new Document(inputPdf);
        if(hocr.isPresent()){
            pdfDoc.convert(bufferedImage -> hocr.get());
        }
        //pdfDoc.validate(new PdfFormatConversionOptions(PdfFormat.PDF_A_3B));
        PdfFormatConversionOptions pdfConvertOptions = new PdfFormatConversionOptions(PdfFormat.PDF_A_3B);
        pdfDoc.convert(pdfConvertOptions);
        pdfDoc.save(outputPdf);
    }

Example:
Input PDF:
Custom-Input.pdf (353.2 KB)

Input HOCR (zipped):
Custom-Input.hocr.7z (5.0 KB)

Result PDF:
Custom-Result.pdf (443.0 KB)

Thanks
Didi

This is not a bug of Aspose.PDF but an incorrectly created OCR with incorrect positions for text. We used for Example tesseract to receive text (image.tesseract.hocr) for the recognized image received in CallBackGetHocr and after adding this result into pdf, text matches positions on the image. image.tesseract.zip (6.0 KB)
