You can display rulers along the top and left side of the Image Preview pane in Fiery ImageViewer.

1. To display rulers in the Image Preview pane, do one of the following:

   • Click the Rulers icon () in the toolbar.

   • Press ctrl+shift+R.

   • Click View > Rulers.

2. Place the cursor at any point along either of the rulers to display a horizontal or vertical guideline across the document canvas to assist with identifying where content is placed on the page.
3. To view both the horizontal and vertical rulers together, click and drag from the top left corner of the ruler. This is useful to measure the vertical and horizontal distance to any point on the image.
