Are you sure you know what right and center alignment means?

> Hi,
>
> I am a Java/J2EE developer in Parsippany, NJ. I have been asked to use
> iText to generate and process PDF files for an upcoming project. One of
> the requirements of this project is to place column text at specified X1
> (lower left X corner), Y1 (lower left Y corner), X2 (upper right X corner)
> and Y2 (upper right Y corner) positions on a PDF file and to align this
> column at a position specified by the client (either left, right or
> center). The parameters for this task (X1, Y1, X2 and Y2 coordinates, type
> of column text to right, type of alignment, etc.) are specified in a
> property file.
>
> In this case, I am trying to write a column text that starts at X1
> position 44 and Y1 position 45 and ending at X2 position 123 and Y2
> position 67. I find that if the column text is left-aligned, then it
> starts at the correct X1 position. However, if its alignment is changed to
> Right or Centered, then its X1 position gets messed up, i.e., it starts at
> an X1 position that is further to the right from the leftmost side of the
> PDF page (e.g., in this case, it will start at position 74 if it is
> center-aligned and at position 124 if it is right-aligned). Is there any

> correct X1 position at the same time?
