Using rulers
Corel Painter lets you show or hide rulers along the top and left sides of the document
window. Each mark on a ruler is known as a tick and represents the selected unit of
measurement. You can set the unit of measurement to pixels, inches, centimeters,
points, or picas.
As you rotate an image in the document window, the rulers scroll to show the position
of the canvas in the document window. The origin of the document is the intersection
of the zero (0) ticks on each ruler. By default, the origin is the upper left corner of the
canvas. Changing the origin resets the location of the zero ticks on the rulers.
To show or hide rulers
• Choose Canvas Rulers, and choose either Show Rulers or Hide Rulers.
To set the ruler units
1 Choose Canvas Rulers Ruler Options.
2 In the Ruler Options dialog box, choose a unit of measurement from the Ruler
Units list box.
You can also open the Ruler Options dialog box by holding down Option
(Mac OS) or Alt (Windows) and clicking the ruler.
To change the document origin
1 Click the box at the intersection of the rulers (upper-left corner of the document
window).
2 Drag diagonally into the document window.
Crosshairs mark the new origin point.
3 Drag the crosshairs to the desired position.
The ruler numbers update to show the new origin as 0,0.
To restore the origin
• Double-click the box at the intersection of the rulers (upper-left corner of the
document window).
