Saving recognition results as a file

To save recognition results to a file or write them to the memory stream, use page_save() method.

The file format is defined by save_format property of recognition settings. The following formats are supported:

Format	Description
file_format::txt	Plain text with line breaks.
file_format::pdf	Portable Document Format.
file_format::docx	Microsoft Word document (version 2007 or later).
file_format::format_rtf	RTF, a universal format for exchanging rich text documents between different word processing programs.
file_format::xlsx	Microsoft Excel spreadsheet (version 2007 or later).
file_format::format_json	JSON is a popular format widely used in software development and data exchange. The de facto standard for websites and REST APIs.
file_format::format_xml	Extensible Markup Language (XML), a universal data exchange and storage format for most systems.

directory dir(".");
const string current_dir = dir.full_name();
const string image = current_dir + "p.png";
const size_t len = 6000;
wchar_t buffer[len] = { 0 };
RecognitionSettings settings;
settings.save_format = file_format::docx;
aspose::ocr::page_save(image.c_str(), "result.docx", settings);

Saving recognition results as a multi-page document

You can merge several recognition results into one document. Simply provide several images as a semicolon-separated string to page_save() method. This can be useful for recognizing books, contracts, articles, and other printouts consisting of multiple pages, as well as for batch recognition.

const size_t len = 4096;
wchar_t buffer[len] = { 0 };
RecognitionSettings settings;
settings.save_format = file_format::pdf;
asposeocr_page_save("1.png;2.jpg;3.jpg", "result.pdf", settings);

When saving recognition results in PDF format, the original image is placed as the background of the resulting document. The recognized text is added as an invisible overlay on top of the background image, and can be searched and copied to the clipboard.
