Recognize TIFF images
Aspose.OCR for Java provides the RecognizeTIFF method that can recognize text on the images extracted from multipage TIFF files. The RecognizeTIFF method takes the TIFF path as a parameter and DocomentRecognitionSettings object. You have to set the number of pages for recognition in the DocomentRecognitionSettings constructor or using setter. 0 means all pages will recognize. The following code snippet demonstrates the use of the RecognizeTiff method to recognize images from multipage TIFF file.
Sample Code
...
// For complete examples and data files, please go to https://github.com/aspose-ocr/Aspose.OCR-for-Java
// The path to the documents directory.
String dataDir = Utils.getSharedDataDir(PerformOCROnPage.class);
// The image path
String imagePath = dataDir + "p3.tiff";
// Initialize an instance of AsposeOcr
AsposeOCRPdf api = new AsposeOCR();
// Set license
License.setLicense("Aspose.Total.lic");
// settings (set the pages amount in constructor).
DocumentRecognitionSettings set = new DocumentRecognitionSettings(1);
set.setStartPage(2);
// Recognize images from TIFF
ArrayList<RecognitionResult> result = api.RecognizeTiff(imgPath, set);
// result
for(RecognitionResult page : result) {
System.out.print("PAGE: ");
printResult(page);
}
}
static void printResult(RecognitionResult result) {
//TEXT
System.out.println("TEXT:\n" + result.recognitionText);
//SKEW
System.out.print("SKEW: ");
System.out.println(result.skew);
//PARAGRAPHS
System.out.println("\nPARAGRAPHS:");
for (String paragraph : result.recognitionAreasText){
System.out.println(paragraph);
}
//PARAGRAPHS COORDS
System.out.println("PARAGRAPHS COORDS:");
for (Rectangle rectangle : result.recognitionAreasRectangles){
System.out.println("X: " + rectangle.x + "Y: " + rectangle.y + "Width: " + rectangle.width + "Height: " + rectangle.height);
}
//LINES
System.out.println("LINES:");
for (LinesResult line : result.recognitionLinesResult){
System.out.print("X: " + line.line.x + "Y: " + line.line.y + "Width: " + line.line.width + "Height: " + line.line.height);
System.out.println(" " + line.textInLine);
}
//POSSIBLE CHOICES FOR CHARACTERS
System.out.println("POSSIBLE CHOICES FOR CHARACTERS:");
for (char[] choices : result.recognitionCharactersList){
System.out.println("character: " + choices[0] + " " + choices[1] + " " + choices[2] + " " + choices[3] + " " + choices[4]);
}
//WARNINGS
System.out.println("WARNINGS:");
for (String warning : result.warnings){
System.out.print(warning);
}
//JSON
System.out.println("JSON:");
System.out.print(result.GetJson());
//SPELL-CHECK CORRECTED TEXT
System.out.println("SPELL-CHECK CORRECTED TEXT:");
System.out.print(result.getSpellCheckCorrectedText());
