Batch recognition

Aspose.OCR for C++ can read up to 20 PNG, JPEG or BMP images in a single call. Images are be provided as a list of files, a folder, or a ZIP archive. Use one of the following methods:

Method	Description
pages_multi()	Read all images from a folder or a ZIP archive. Subfolders and nested archives are not supported.
pages_multi_array()	Read images provided as an array or paths.
pages_multi_array_from_raw_bytes()	Read images provided as pixel arrays.

These methods allow you to optionally customize recognition accuracy, performance, and other settings.

Read images from ZIP achive

std::string image_path = "source.zip";
const size_t len = 4096;
wchar_t buffer[len] = { 0 };
RecognitionSettings settings;
size_t res_len = aspose::ocr::pages_multi(image_path.c_str(), buffer, len, settings);
std::wcout << buffer;

Read images from folder

std::string image_path = "../book/pages";
const size_t len = 4096;
wchar_t buffer[len] = { 0 };
RecognitionSettings settings;
size_t res_len = aspose::ocr::pages_multi(image_path.c_str(), buffer, len, settings);
std::wcout << buffer;

Read images from array

const int files_number = 2;
const char** files = new const char* [files_number];
files[0] = "../book/pages/page1.png";
files[1] = "../book/pages/page2.png";
const size_t len = 4096;
wchar_t buffer[len] = { 0 };
RecognitionSettings settings;
aspose::ocr::pages_multi_array(files, files_number, buffer, len, settings);
std::wcout << buffer;
