Fax images are big, so don't worry about the size on screen. A typical fax image is 1728 pixels across, and 2200 pixels down. The first number in each line is the all important 'field marker'. The field name is for reference only. When you build your own address dialog, then you can define what ever fields you want.
Text is word wrapped to fill the display box.
For now there are no checks for height overflow. Any Windows supported font can be used as the text font. Best results occur when you use a true type font. Point sizes are relative to the output page size. A standard visible size is around 40 to 50 points.
