When selected, the Colours dialog box is displayed and allows the choice of a colour with which the image bars and text font will be rendered when the barcode image is redrawn.
The Barcode settings dialog also displays the current setting for the font used for human readable form and a Change button that allows the normal Windows Font dialog to be displayed and an alternative font selected.
Other options for the barcode may be set by puching the Options button that displays the Options dialog.
