public final class TextDevice extends PageDevice
Represents class for converting pdf document pages into text.
The example demonstrates how to extract text on the first PDF document page. Document doc = new Document(inFile); String extractedText; ByteArrayOutputStream ms = new ByteArrayOutputStream(); try { // create text device TextDevice device = new TextDevice(); // convert the page and save text to the stream device.process(doc.getPages().get_Item(1), ms); // use the extracted text extractedText = Encoding.getUnicode().getString(ms.toByteArray()); ms.close(); } catch (IOException e) { e.printStackTrace(); } The {@code TextDevice} object is basically used to extract text from pdf page.

getEncoding
public Charset getEncoding()
Gets encoding of extracted text.
Returns: Charset element
The example demonstrates how to represent extracted text in UTF-8 encoding. Document doc = new Document(inFile); String extractedText; // create text device TextDevice device = new TextDevice(java.nio.charset.Charset.forName(“UTF-8”)); // convert the page and save text to the stream device.process(doc.getPages().get_Item(1), outFile);
getEncodingInternal
public TextEncodingInternal getEncodingInternal()
Gets encoding of extracted text.
Returns: TextEncodingInternal element
The example demonstrates how to represent extracted text in UTF-8 encoding. Document doc = new Document(inFile); String extractedText; // create text device TextDevice device = new TextDevice(java.nio.charset.Charset.forName(“UTF-8”)); // convert the page and save text to the stream device.process(doc.getPages().get_Item(1), outFile);
getExtractionOptions
public TextExtractionOptions getExtractionOptions()
Gets text extraction options.
Returns: TextExtractionOptions element
The example demonstrates how to extracted text in raw order. Document doc = new Document(inFile); String extractedText; // create text device TextDevice device = new TextDevice(new TextExtractionOptions(TextExtractionOptions.TextFormattingMode.Raw)); // convert the page and save text to the stream device.process(doc.getPages().get_Item(1), outFile);
process

The example demonstrates how to extract text on the first PDF document page. Document doc = new Document(inFile); String extractedText; ByteArrayOutputStream ms = new ByteArrayOutputStream(); // create text device TextDevice device = new TextDevice(); // convert the page and save text to the stream device.process(doc.getPages().get_Item(1), ms); // use the extracted text extractedText = Encoding.getUnicode().getString(ms.toByteArray()); ms.close();
processInternal
Convert page and save it as text stream.
setEncoding
Sets encoding of extracted text.
setEncodingInternal
Sets encoding of extracted text.
