I Need to Fetch the Color of Text in a PDF using pdfbox 2.0.0 , for the same i have written java code as 

import java.io.ByteArrayOutputStream;
import java.io.File;
import java.io.IOException;
import java.io.OutputStreamWriter;

import org.apache.pdfbox.text.TextPosition;

/**
 * This is an example on how to get the colors of text. Note that this will not tell the background,
 * and will only work properly if the text is not overwritten later, and only if the text rendering
 * modes are 0, 1 or 2. In the PDF 32000 specification, please read 9.3.6 "Text Rendering Mode" to
 * know more. Mode 0 (FILL) is the default. Mode 1 (STROKE) will make glyphs look "hollow". Mode 2
 * (FILL_STROKE) will make glyphs look "fat".

                PDFTextStripper stripper = new PDF_Box_1();
                stripper.setSortByPosition(true);
                stripper.setStartPage(0);
                stripper.setEndPage(document.getNumberOfPages());

                Writer dummy = new OutputStreamWriter(new ByteArrayOutputStream());
               
                stripper.writeText(document, dummy);
            }
        
    }

    @Override
    protected void processTextPosition(TextPosition text)
    {
        super.processTextPosition(text);

        PDColor strokingColor = getGraphicsState().getStrokingColor();
        PDColor nonStrokingColor = getGraphicsState().getNonStrokingColor();
        String unicode = text.getUnicode();
        RenderingMode renderingMode = getGraphicsState().getTextState().getRenderingMode();
        System.out.println("Unicode:            " + unicode);
        System.out.println("Rendering mode:     " + renderingMode);
        System.out.println("Stroking color:     " + strokingColor);
        System.out.println("Non-Stroking color: " + nonStrokingColor);
        System.out.println("Non-Stroking color: " + nonStrokingColor);
        System.out.println();

        // See the PrintTextLocations for more attributes
    }

    /**
     * This will print the usage for this document.
     */
/*    private static void usage()
    {
        System.err.println("Usage: java " + PDF_Box_1.class.getName() + "D://Vimal//New folder//b1.pdf");
    }*/
}

But by using this I am getting Text of a Byte , but i want it for the word . Can you please help me in how to do this.
