DocWire DocToText - Powered by Silvercoders 5.0.5
A multifaceted, data extraction software development toolkit that converts all sorts of files to plain text and html. Written in C++, this data extraction tool has a parser able to convert PST & OST files along with a brand new API for better file processing. To enhance its utility, DocToText, as a data extraction tool, can be integrated with other data mining and data analytics applications. It comes equipped with a high grade, scriptable and trainable OCR that has LSTM neural networks based character recognition. This document parser is able to extract metadata along with annotations and supports a list of formats that include: DOC, XLS, XLSB, PPT, RTF, ODF (ODT, ODS, ODP), OOXML (DOCX, XLSX, PPTX), iWork (PAGES, NUMBERS, KEYNOTE), ODFXML (FODP, FODS, FODT), PDF, EML, HTML, Outlook (PST, OST), Image (JPG, JPEG, JFIF, BMP, PNM, PNG, TIFF, WEBP) and DICOM (DCM)

Detailed Description

The Transformer transforms data from Importer or from another Transformer.

auto reverse_text = [](doctotext::Info &info) {
std::reverse(info.plain_text.begin(), info.plain_text.end())}; // create function to reverse text in callback
TransformerFunc transformer(reverse_text); // wraps into transformer
Importer(parser_manager, "test.pdf") | transformer | PlainTextExporter | std::cout; // reverse text in pdf file
doctotext::Importer
The Importer class. This class is used to import a file and parse it using available parsers.
