public class PrintTextColors extends org.apache.pdfbox.text.PDFTextStripper
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".
