The Units tab controls ruler options and the default resolutions for new images.
In the Rulers group box, choose from the following options:
Choose a measurement system for the rulers from the Display units drop-down list.
Choose Toolbar colors to have the ruler color match Paint Shop Pro’s toolbars or choose Black on White rulers.
In the Default Resolution group box choose a measurement system from the drop-down list and enter the default resolution for images that do not contain resolution information, such as scanned images.
Mark the Vector Coordinates check box to snap objects to the center of pixels while they’re moving. You will have to be zoomed in at a very high percentage in order to see this.
