GPU version: 21.7.0
All Features
| Key | Summary | Category |
|---|---|---|
| OCRCPP-245 | Import Craft model and get the result | Enhancement |
| OCRCPP-241 | Import optimized models | Enhancement |
Enhancements
- reduced package size
- added ability to choose mode of areas detection
Public API and Backwards Incompatible Changes
New API
| Enum | Fields |
|---|---|
| detect_areas_mode_enum | |
NONE - Doesn’t detect paragraphs. Better for a simple one-column document without pictures. | |
| DOCUMENT = Detects paragraphs uses NN model for documents. Better for multicolumn document, document with pictures or with other not text objects. | |
| PHOTO = Detects paragraphs uses NN model for photos. Better for image with a lot of pictures and other not text objects. | |
| COMBINE = Detects paragraphs with text and then uses other NN model to detect areas inside of paragraphs. Better for images with complex structure. | |
| Field | Description |
|---|---|
| detect_areas_mode_enum detect_areas_mode | |
Field in RecognitionSettings structure. Default value: detect_areas_mode_enum::DOCUMENT | |
Removed APIs
No Changes
Example (C++17 since filesystem)
#include <iostream>
#include <aspose_ocr.h>
#include <filesystem>
#include <corecrt_io.h>
#include <fcntl.h>
int main()
{
_setmode(_fileno(stdout), _O_U16TEXT);
//Current directory const
std::filesystem::path path{ std::filesystem::current_path() };
/* asposeocr_set_license */
const std::string lic = "/Aspose.Total.lic";
std::filesystem::path license = path.string() + lic;
asposeocr_set_license(license.string().c_str());
/* asposeocr_set_license */
bool lic_result = asposeocr_get_state();
//Recognize image
const string image = "img.jpg";
// Prepare buffer for result (in symbols, len_byte = len * sizeof(wchar_t))
const size_t len = 4096;
wchar_t buffer[len] = { 0 };
/* asposeocr_page_settings*/
RecognitionSettings settings;
settings.detect_areas_mode = detect_areas_mode_enum::COMBINE;
size_t size = asposeocr_page_settings(image.c_str(), buffer, len, settings);
#ifdef _WIN32
setmode(_fileno(stdout), 0x00020000);
#else
setlocale(LC_CTYPE, "");
#endif
std::wcout << buffer;
