Preview Units
The preview area of a symbology window shows the dimensions of the barcode with your customization. This option sets the unit of measure to millimeters, inches, or pixels.
Editor & Settings Preview Background
These options set the background pattern of the barcode preview areas. A checkerboard background makes it easy to see the size and shape of a barcode that has a white background. Several backgrounds are available, but the fourth background option is unsupported.
