Public API changes and backwards compatibility
This section lists all public API changes introduced in Aspose.OCR for .NET 26.1 that may affect the code of existing applications.
Added public APIs:
The following public APIs have been introduced in this release:
Aspose.OCR.AsposeOcr.RecognizeTables - a new method
Detect all tables in the image, identify their structure, recognize text within each cell, and return a list of OCRTablePage objects.
If the Language property is not specified, the OCR engine defaults to a lightweight Latin character model, which does not support diacritics.
New Methods
| Method | Description |
|---|---|
RecognizeTables(OcrInput images, Language language = Language.Latin) | Detect tables and structure and recognizes text cells. |
Aspose.OCR.AI.KeywordsAIProcessor - a new class
Performs AI-based keyword and numeric value search in OCR-recognized text. You can set the keywords used for searching OCR-recognized text and get the JSON-formatted string with the following structure:
[
{
“keyword”: “string”,
“value”: “string”,
“number”: “string”
}
]
Updated public APIs:
The following public APIs have been updated in this release:
Aspose.OCR.OcrOutput.GetTableData
Return a list of OCRTablePage objects.
Aspose.OCR.AI.AIResult
Added property ‘Result’
Removed public APIs:
The following public APIs was removed:
Aspose.OCR.AI.AIResult
Removed property RecognitionText
Examples
The code samples below illustrate the changes introduced in this release:
Detect and Recognize tables
Aspose.OCR.AsposeOcr recognitionEngine = new Aspose.OCR.AsposeOcr();
// Add an image to OcrInput object
Aspose.OCR.OcrInput input = new Aspose.OCR.OcrInput(Aspose.OCR.InputType.SingleImage);
input.Add("source.png");
// Detect all tables and recognize text in cells
List<Aspose.OCR.OCRTablePage> results = recognitionEngine.RecognizeTables(input);
// Print result
foreach (OCRTable table in results[0].Tables)
{
foreach (OCRTableRow row in table.Rows)
{
foreach (OCRTableCell c in row.Cells)
Console.WriteLine($"Row [{row.RowIndex}, col {c.ColumnIndex}] = {c.Text}");
}
}
Get values from image by keywords (using AI)
Aspose.OCR.AsposeOcr recognitionEngine = new Aspose.OCR.AsposeOcr();
// Add an image to OcrInput object
Aspose.OCR.OcrInput input = new Aspose.OCR.OcrInput(Aspose.OCR.InputType.SingleImage);
input.Add("source.png");
// Recognize image
OcrOutput results = recognitionEngine.Recognize(input);
// Set up AI component
Aspose.OCR.AI.AsposeAI ai = new Aspose.OCR.AI.AsposeAI();
Aspose.OCR.AI.KeywordsAIProcessor proc = new Aspose.OCR.AI.KeywordsAIProcessor();
// Set up keywords list
proc.SetKeywords(new string[] { "Total", "Tax" });
ai.SetPostProcessor(proc);
ai.RunPostprocessor(results);
// Print results (json)
Console.WriteLine(proc.GetResult()[0].Result);
// [
// {
// "keyword": "Total",
// "value": "Donald Patrick",
// "number": "101"
// },
// {
// "keyword": "Tax",
// "value": "Samuel Samson",
// "number": "101"
// }
//]
