Does anyone know how the pixels are calculated in the report designer?

If I create a new report with the scale unit set to pixels, drop a field onto my report, then save the report and open up the .frx file the VPOS is something like 33437.500 and the HPOS is 15104.167

If I create a form and do the same thing, the TOP property is like 25 and the LEFT property is 30.

What I am trying to accomplish is to take a simple report form (no data groupings, headers, footers, etc.) and scan through the .frx file getting the field positions and then creating a form object and adding textbox objects in the same position on the form as they are on the report.

There seems to be some pixel calculation factor taking place that I just can't seem to figure out.

Any help would be appreciated!
