Usage examples
The examples below illustrates the changes introduced in this release:
Reading Hindi images
const std::string filePath = current_dir + "/hindi.jpg";
const size_t len = 4096;
wchar_t buffer[len] = { 0 };
RecognitionSettings settings;
settings.all_image = true;
settings.language_alphabet = language::hin;
size_t size = asposeocr_page_settings(filePath.c_str(), buffer, len, settings);
std::wcout << buffer;
Saving recognition results in RTF format
directory dir(".");
#ifdef _WIN32
string current_dir = dir.full_name() + "/";
#else
string current_dir = dir.full_name() + "/";
#endif
const std::string filePath = current_dir + "/source.png";
RecognitionSettings settings;
settings.save_format = file_format::format_rtf;
asposeocr_page_save(filePath.c_str(), "test_res.rtf", settings);
ASSERT_TRUE(exists_test("test_res.rtf") == true);
std::remove("test_res.rtf");
