Aspose.OCR for C++
Overview
processes scanned images or even smartphone photos in JPEG format and creates JPEG documents containing recognized text. To add it to your project, you just need to get Aspose.OCR
Aspose Maven Repository or specify Aspose Maven Repository configuration and install it within your Maven-based project by adding the following configurations to the pom.xml. For Graddle, Ivy, Sbt examples check out our repository .
Package Manager Console Command
PM> Install-Package Aspose.OCR.Cpp
With C++ OCR and just a few lines of code, you can create full-featured application that converts an JPEG image to PDF document:
- Create an instance of AsposeOcr class
- Call AsposeOCR.asposeocr_page() method
- Pass the JPEG file path as parameter
- AsposeOCR.asposeocr_page returns a String or file of PDF type
System Requirements
Before running the example, make sure that Microsoft.ML.OnnxRuntime 1.7.0 or above is added to the project. It should be automatically installed if you install Aspose.OCR via NuGet Package Manager.
- NET Standard 2.0+ compatible solution
- Aspose.OCR for .NET referenced in your project.
std::string img_path = "../srcSample.png";
// Prepare buffer for result (in symbols, len_byte = len * sizeof(wchar_t))
const size_t len = 4096;
wchar_t bfr[len] = { 0 };
size_t result = aspose::ocr::page(image_path.c_str(), bfr, len);
//Print result
std::wcout << bfr << L"\n";
JPEG What is JPEG File Format
A JPEG is a type of image format that is saved using the method of lossy compression. The output image, as result of compression, is a trade-off between storage size and image quality. Users can adjust the compression level to achieve the desired quality level while at the same time reduce the storage size. Image quality is negligibly affected if 10:1 compression is applied to the image. The higher the compression value, the higher the degradation in image quality.

Portable Document Format (PDF) is a type of document created by Adobe back in 1990s. The purpose of this file format was to introduce a standard for representation of documents and other reference material in a format that is independent of application software, hardware as well as Operating System. The PDF file format has full capability to contain information like text, images, hyperlinks, form-fields, rich media, digital signatures, attachments, metadata, Geospatial features and 3D objects in it that can become as part of source document.
