Special Text Fields
Two special field names exist: the PRC field and the DES field. These fields are predefined
with certain enhancements to allow more flexibility in “price+description” environments.
PRC Field Fonts
The PRC field uses PNG format graphics to display the numbers, decimal point and currency
mark. Portable Network Graphics (PNG) format is used because it supports transparency,
allowing for customization and integration within the background.
Each character available in the PRC field (“0” - ”9”, “.” and a currency mark) is contained
in its own image located in the directory pointed to by the Numeral Image Directory
command line argument. The names of the files are simply “1.png”, “2.png”, etc... for the
numerals and “dollar.png” for the currency mark. The decimal point should be named
“point.png”, and a blank image that should be used for spaces should be called
“blank.png”. The default images are shown below.
