Topic: Possible text offset problem?

I tried to figure this out on my own but I've been working on this for about a week to no avail. At the bottem of this message is the screenshots of the problems I'm having.

The main problem is that font offsets seem to be grosly off, but only in certain cases. Because it only happens in a few text runs inside a block of over 100 text runs, I believe that there is simply some parameter I am not accounting for. Here is how I currectly get my text positions:

1) Get the text matrix of the current text run with PDETextGetMatrix. (I use the HScale param accordinly but this is always 1.0 with all my PDFs)
2) Get the character and word spacing for the text run.
3) Get the font size (i set the font's height to this size due to the documentation not really explaining what 'font size' means) but it seems to look correct in the output.


When I render I have my own custom text drawing function that has a floating-point X offset variable that increments the X offset by the width of the characte printed + the character spacing (and possibly + the width of the word spacing if it is a space character).

This looks fine for the most part but some things simply don't look right.

Any clue?
