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 TXT 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 TXT 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.

A file with .TXT extension represents a text document that contains plain text in the form of lines. Paragraphs in a text document are recognized by carriage returns and are used for better arrangement of file contents. A standard text document can be opened in any text editor or word processing application on different operating systems. All the text contained in such a file is in human-readable format and represented by sequence of characters.
