Polygon annotation in PDFBox PDAnnotation

I want to add the polygon in the PDF at the given coordinates, I referred this link for adding the annotation of circle and rectangle, but it does not contain anything for polygon. Does anyone know how to do it? Or does anyone know where do I get all documentation about PDFBox annotation.
Here I am sharing what I'vs done until now. But I couldn't proceed further.

As far I have seen, There isn't any method for adding vertices in polygon in PDAnnotation jar. So is there any way we can draw polygon here?
Thanks.

Here's some code that will soon be added to the AddAnnotations.java example from the source code download:
static final float INCH = 72;
float pw = page1.getMediaBox().getUpperRightX();
float ph = page1.getMediaBox().getUpperRightY();
PDAnnotationMarkup polygon = new PDAnnotationMarkup();
polygon.getCOSObject().setName(COSName.SUBTYPE, PDAnnotationMarkup.SUB_TYPE_POLYGON);
position = new PDRectangle();
position.setLowerLeftX(pw - INCH);
position.setLowerLeftY(ph - INCH);
position.setUpperRightX(pw - 2 * INCH);
position.setUpperRightY(ph - 2 * INCH);
polygon.setRectangle(position);
polygon.setColor(blue); // border color
polygon.getCOSObject().setItem(COSName.IC, red.toCOSArray()); // interior color
COSArray triangleVertices = new COSArray();
triangleVertices.add(new COSFloat(pw - INCH));
triangleVertices.add(new COSFloat(ph - 2 * INCH));
triangleVertices.add(new COSFloat(pw - INCH * 1.5f));
triangleVertices.add(new COSFloat(ph - INCH));
triangleVertices.add(new COSFloat(pw - 2 * INCH));
triangleVertices.add(new COSFloat(ph - 2 * INCH));
polygon.getCOSObject().setItem(COSName.VERTICES, triangleVertices);
polygon.setBorderStyle(borderThick);
annotations.add(polygon);
to adjust your own code, you need to adjust the rectangle and pass your vertices:
position.setLowerLeftX(418);
position.setLowerLeftY(110);
position.setUpperRightX(523);
position.setUpperRightY(133);
polygon.setRectangle(position);
float[] vertices = {418, 110, 523, 110, 522, 132, 419, 133};
COSArray verticesArray = new COSArray();
for (float v : vertices)
verticesArray.add(new COSFloat(v));
polygon.getCOSObject().setItem(COSName.VERTICES, verticesArray);
This is for 2.0 only. In 3.0 there will be a PDAnnotationPolygon type with appropriate methods. That version will also support the construction of appearance streams, i.e. you will be able to show the PDF with other viewers than Adobe Reader. Most viewers, e.g. PDF.js and PDFBox don't build missing appearances so you'll see nothing.
If you need the appearance for 2.0 you can try with the code in the file ShowAnnotation-6.java in https://issues.apache.org/jira/browse/PDFBOX-3353 .
To test with the 3.0 version, get the jar here:
https://repository.apache.org/content/groups/snapshots/org/apache/pdfbox/pdfbox-app/3.0.0-SNAPSHOT/
To build the appearance, call polygon.constructAppearances();

LineBreakMeasurer produces result differ from MS Word / LibreOffice

In a swing application, I need to foresee text wrapping of a string like when putting it in a word processor program such as MS Word or LibreOffice. Providing the same width of the displayable area, the same font (face and size) and the same string as following:
displayable area width: 179mm (in a .doc file, setup an A4 portrait page - width = 210mm, margin left = 20mm, right = 11mm; the paragraph is formatted with zero margins)
Font Times New Roman, size 14
Test string: Tadf fdas fdas daebjnbvx dasf opqwe dsa: dfa fdsa ewqnbcmv caqw vstrt vsip d asfd eacc
And the result:
On both MS Word and LibreOffice, that test string is displayed on single line, no text wrapping occurs.
My bellow program report a text wrapping occurs, 2 lines
Line 1: Tadf fdas fdas daebjnbvx dasf opqwe dsa: dfa fdsa ewqnbcmv caqw vstrt vsip d asfd
Line 2: eacc
Is it possible to achieve the same text wrapping effect like MS Word in swing? What could be wrong in the code?
Bellow the my program
public static List<String> wrapText(String text, float maxWidth,
Graphics2D g, Font displayFont) {
// Normalize the graphics context so that 1 point is exactly
// 1/72 inch and thus fonts will display at the correct sizes:
GraphicsConfiguration gc = g.getDeviceConfiguration();
g.transform(gc.getNormalizingTransform());
AttributedCharacterIterator paragraph = new AttributedString(text).getIterator();
Font backupFont = g.getFont();
g.setFont(displayFont);
LineBreakMeasurer lineMeasurer = new LineBreakMeasurer(
paragraph, BreakIterator.getWordInstance(), g.getFontRenderContext());
// Set position to the index of the first character in the paragraph.
lineMeasurer.setPosition(paragraph.getBeginIndex());
List<String> lines = new ArrayList<String>();
int beginIndex = 0;
// Get lines until the entire paragraph has been displayed.
while (lineMeasurer.getPosition() < paragraph.getEndIndex()) {
lineMeasurer.nextLayout(maxWidth);
lines.add(text.substring(beginIndex, lineMeasurer.getPosition()));
beginIndex = lineMeasurer.getPosition();
}
g.setFont(backupFont);
return lines;
}
public static void main(String[] args) throws Exception {
JFrame frame = new JFrame();
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
JTextPane txtp = new JTextPane();
frame.add(txtp);
frame.setSize(200,200);
frame.setVisible(true);
Font displayFont = new Font("Times New Roman", Font.PLAIN, 14);
float textWith = (179 * 0.0393701f) // from Millimeter to Inch
* 72f; // From Inch to Pixel (User space)
List<String> lines = wrapText(
"Tadf fdas fdas daebjnbvx dasf opqwe dsa: dfa fdsa ewqnbcmv caqw vstrt vsip d asfd eacc",
textWith,
(Graphics2D) txtp.getGraphics(),
displayFont);
for (int i = 0; i < lines.size(); i++) {
System.out.print("Line " + (i + 1) + ": ");
System.out.println(lines.get(i));
}
frame.dispose();
}

+1 for the question
From my experience with text editors it's not possible to achieve exactly the same measuring.
You can try to play with DPI there is default DPI=72 and 96 on windows.
Also you can try to play with all the rendering hints of the Graphics - text antialiasing etc.

Tactics for parsing fixed-width text log in Java

I'm trying to figure out how to best parse the following log file, splitting each section seperated by the horizontal lines and extract various pieces of data, e.g. 'COMPANY123', 'BIMMU', the date (2/18 etc.) and then create a string containing all of the other data contained in a section delimited by the horizontal lines.
I.e., I want to create an array of 'statement' objects each with the following attributes:
Company name, Account, Date, Data.
E.g. for the second record below,
Account = 'BIMMU'
Firm = 'Super Corporation'
Date= 9/14/11
Data = '* * * * * * * * TODAYS ACCOUNT ACTIVITY * * * * * * * * * * *
9/14/11 Y9 CALL OESX OCT 11 ........ etc'
The log is a fixed-width text file and the variables (date etc.) always occur at the same position in the line, e.g. sSalesCode = line.substring(142, 147);
Should I maybe do this in two passes, e.g. split the code into sections delimited by the horizontal line, and then parse these sections individually?
Just writing this out here has helped me get my train of thought, but if anybody else has any smart ideas then it would be great to hear them.

You can try to use framework Fixedformat4j. It uses annotations and works fast. I have implemented it partially for my project to understand how it works.
You can create class with annotations like this:
#Record
public class LogRecord {
private String firm;
private String user;
private Date logonDate;
private String logData;
public String getFirm() {
return firm;
}
#field(offset=10, length=10)
public void setFirm(String firm) {
this.firm = firm;
}
public String getUser() {
return user;
}
#field(offset=0, length=10)
public void setUser(String user) {
this.user = user;
}
public Date getLogonDate() {
return logonDate;
}
#field(offset=nn, length=8)
#FixedFormatPattern("mm/dd/yy")
public void setLogonDate(Date logonDate) {
this.logonDate = logonDate;
}
public String getLogData() {
return logData;
}
#field(offset=mm, length=yy)
public void setLogData(String logData) {
this.logData = logData;
}
}
And then instantiate it with FixedFormatManager.

i had similar problem recenly, i ended up using Flapjack (Google Code: Flapjack)... See the examples on google code, i guess it should help you out.

You may be aware of this already, but it appears that somewhere, the code is trying to access a property called "varchar" on the Product object:
Caused by: java.lang.NoSuchMethodException: Unknown property 'varchar' on class 'class ar.com.fdvs.dj.test.domain.Product' at .....
I don't see where this is happening in your example. It may be that there is a place where name is expected and you are instead passing in type. Or somewhere in your configuration, you've got name and type switched around, so it's looking for a field named "varchar". Does that make sense?
In general, I find that the "Caused by" portion of the error log is the most informative.
