Rulers, Unit of Measurement
The rulers on the top and left sides of the Preview window help you with
measurement and alignment, marking off measurement according to the
selected unit (inch, pica, pixel, etc.).
The rulers change when dimensions are altered in the preview area of the
Overview Setup command (in the Preferences menu). For example, if you
change the preview area size from 5" x 8" to 6" x 9", the rulers will change
accordingly.
The unit of measurement can be selected in two ways:
• Through the Unit box in the Settings window.
• Through the arrow at the corner where the rulers meet in the Preview
window. The drop-down menu through this method also lets you format the
text color and background color of your rulers.
The options for unit of measurement include inch, centimeter, millimeter, point,
pica, and pixel. The pixel option is dimmed if the selected resolution unit is lpi.
Select the unit of measurement for the rulers in either
the Settings window or the Preview window.
