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.
