property TextFont: TFont;
For the TBarcode_UPCA, TBarcode_UPCE, TBarcode_UPCE0, and TBarcode_UPCE1 barcode components, if the human readable text is displayed, and the TextAlignment property is set to taCustom, the property specifies the font size of the left quiet zone mark and the right quiet zone mark. Otherwise it will be ignored. See diagram:
The font name, style, and color of the left quiet zone mark and the right quiet zone mark are specified by the TextFont property. The color value that's specified by the SpaceColor property will be used as the background color.
It defaults to 0, meaning that the font size that's specified by the TextFont property. If the property value is set to less than 0, or greater than the font size that's specified by the TextFont property, the font size that's specified by the TextFont property will be used too.
