Addon

How can I generate PDF/A files?

Dynamic Web TWAIN does not support the generation of PDF/A files. However, OCR Basic and OCR Pro Addon support.

For OCR Basic, you can set SetOutputFormat to OCROF_PDFPLAINTEXT_PDFX (3) or OCROF_PDFIMAGEOVERTEXT_PDFX (4). Check out the enum API here: EnumDWT_OCROutputFormat.

For OCR Pro, configure the output format through Settings, use OutputFormat and PDFAVersion to specify the output format and PDF/A version.

For the differences between OCR Basic and OCR Pro, please refer to this article.
