Scaling Rectangle
We have document management application that creates graphic annotations for documents of various types such as word, text, spreadsheets, PDF and such. I need to take the PDFs and merge the graphic annotations by creating PDF annotations and placing them in the PDF. The problem I am having is that the graphic annotation were positioned using 96 dpi and the PDF specification is 72 dpi. I tried scaling the rectangle from document management application down by 25 percent as this is roughly the difference going from 96 to 72 but the annotations don't line up. Below is the code I use to scale the rectangle.
java.awt.Rectangle borderRect = annotation.getRefreshRect();
float x = (float) (borderRect.x / 1.25);
float y = (float) (borderRect.y / 1.25);
float h = (float) (borderRect.height/ 1.25);
float w = (float) (borderRect.width/ 1.25);
PDRectangle borderLocation = new PDRectangle(x,
(pageHeight - y)-h,
w,
y);
The placement is in the ballpark but still way off. How should I approach this problem.

Thank you for your help. The "getRefreshRect" method is an API method from the document management application that the users used to create the annotations. Your suggestions worked. I don't know what I was thinking. It was so obvious only after the fact where my error was.

1 / 96 * 72 = 0.75 so you should multiply by 0.75 instead of dividing by 1.25. Because 1 / 1.25 = 0.8
Another idea:
Could it be that the PDF has a cropbox and that the application didn't know what when it calculated the position?
There is no "getRefreshRect" method in PDFBox.
If you still don't get it to work, how about creating a PDF that has a grid at 100, 200, 300 etc. and then place annotations to see what numbers come up. To draw in a PDF, see the CreateLandscapePDF.java example in the source code download (moveto, lineto, stroke)
