The designer has two rulers at the top and left side of the editor window. Rulers provide a visual reference on the actual size of report and report objects.
Rulers use the units configured for the edited report to display the measurement marks.
Guidelines can be placed on rulers. Guidelines provide a visual reference in the shape of vertical or horizontal lines stretching across the report page. Clicking on the ruler's active (white) area creates a new guideline at that position. Dragging a guideline around changes its position. A guideline is deleted by dragging it outside of the ruler's active area.
