Public API changes and backwards compatibility
This section lists all public API changes introduced in Aspose.OCR for C++ 22.9 that may affect the code of existing applications.
Added public APIs:
The following public APIs have been introduced in this release:
Receipt recognition.
Added a function asposeocr_recognize_receipt
that is specifically tailored for extracting text from printed receipts.
Recognition of small fonts
Added the small_text
image recognition setting. When enabled (set to true
), it activates a special upscaling algorithm that greatly improves small font recognition and detection of dense lines.
Updated public APIs:
No changes.
Removed public APIs:
No changes.
Usage examples
The examples below illustrates the changes introduced in this release:
Receipt recognition.
void read_receipt()
{
const std::string filePath = current_dir + "/source.png";
// Set Chinese recognition language
RecognitionSettings recognitionSettings;
recognitionSettings.language_alphabet = language::chi;
// Extract text from receipt
const size_t len = 4096;
wchar_t buffer[len] = { 0 };
size_t result = asposeocr_recognize_receipt(filePath.c_str(), buffer, len, recognitionSettings);
}
Recognition of small fonts
void read_small_text()
{
const std::string filePath = current_dir + "/source.png";
// Activate font upscaling
RecognitionSettings recognitionSettings;
recognitionSettings.small_text = true;
// Extract text from image
const size_t len = 10000;
wchar_t buffer[len] = { 0 };
size_t result = asposeocr_page_settings(f.c_str(), buffer, len, recognitionSettings);
}
