    Object[] PDFObjectsAsPoJos=extract.getFormComponentsFromDocument("Mabel", ReturnValues.FORMOBJECTS_FROM_NAME);

    //a form with PDF Reference 25 0 R
    Object[] PDFObjectsAsPoJos=extract.getFormComponentsFromDocument("25 0 R", ReturnValues.FORMOBJECTS_FROM_REF);

    //all Swing versions of the Form objects
    Object[] swingComponents=extract.getFormComponentsFromDocument(null, ReturnValues.GUI_FORMS_FROM_NAME);

    //all formNames on page 5
    Object[] names=extract.getFormComponentsFromPage(null, ReturnValues.FORM_NAMES,5);

    // all forms in document called Mabel on page 5
    Object[] PDFObjectsAsPoJos=extract.getFormComponentsFromPage("Mabel", ReturnValues.FORMOBJECTS_FROM_NAME,5);

    //a form with PDF Reference 25 0 R on page 5
    Object[] PDFObjectsAsPoJos=extract.getFormComponentsFromPage("25 0 R", ReturnValues.FORMOBJECTS_FROM_REF,5);

    //all Swing versions of the Form objects on page 5

//Convenience static method (see class for additional options)
ExtractClippedImages.writeAllClippedImagesToDir("inputFileOrDirectory", "outputDir", "outputImageFormat", new String[] {"imageHeightAsFloat", "subDirectoryForHeight"});

//Convenience static method (see class for additional options)
ExtractTextAsWordList.writeAllWordlistsToDir("inputFileOrDirectory", "outputDir", -1);

//Convenience static method (see class for additional options)
ArrayList resultsForPages = FindTextInRectangle.findTextOnAllPages("/path/to/file.pdf", "textToFind");

PrintPdfPages print = new PrintPdfPages("C:/pdfs/mypdf.pdf");

if (print.openPDFFile()) {
    print.printAllPages("Printer Name");
}

//Convenience static method (see class for additional options)
