To remove a guide, drag and drop it anywhere outside the page area. A ruler guide line appears parallel to the ruler ( Alt-drag to create the guide at 90 degrees to the ruler). To create a ruler guide, click on a ruler, hold down your mouse button, then drag onto your page. Guides are by default “sticky” so that stuck objects can be dragged around the page by their ruler guide-a great way to move previously aligned objects in bulk and simultaneously. PagePlus lets you to set up horizontal and vertical ruler guides-non-printing lines you can use to align headlines, pictures, and other layout elements. On the View menu, check or uncheck a guide option. Use Bleed area guides to specify the extra margin you want to allow around the original Page Setup dimensions or “trim area.” Note that if the setting is zero or you have View>Bleed Area Guides unchecked, you won’t see the bleed area displayed.įor ruler guides, use the Guides tab to precisely create, edit or delete ruler guides, or more commonly, just drag the guides from the rulers. If you want rows or columns of uneven width, first place them at fixed intervals, then drag to reposition them as required. Use the Row and Column Guides section to define guides for rows and columns. Remember to set up your margins so that you leave enough room for any intended header or footer. The dialog also provides options for Balanced margins (left matching right, top matching bottom) or for Mirrored margins on facing pages where the “left” margin setting becomes the “inside,” and the “right” margin becomes the “outside.” In the Margin Guides section, you can set the left, right, top, and bottom page margins individually, or click the From Printer button to derive the page margin settings from the current printer settings. Then in the Layout Guides dialog, use the Margins tab to set guide lines for page margins, rows and columns, and bleed areas. They are “ sticky” so that objects can snap to them, then be moved collectively with guide movement.ĭefining layout guides To define layout guides:Ĭlick Layout Guides on the Page context toolbar, Layout Guides… from the File menu, or right-click on a blank part of the page and choose Layout Guides. Ruler guides are free-floating red lines that you set by clicking and dragging from the rulers. Note that these guide lines are just a visual aid only the Bleed limit setting in the Publish as PDF or Print dialog extends the actual output page size. With bleed guides switched on, the page border expands by a distance you specify, and the trim edge is shown with dashed lines and little “scissors” symbols. To allow for inaccuracies in the trimming process in professional printing, it’s a good idea to extend these elements beyond the “trim edge”-the dimensions defined by your Page Setup. Rather, they serve as visual aids that help you match the frame layout to the desired column layout.īleed area guides assist you in positioning “bleed” elements that you want to run to the edge of a trimmed page. Unlike the dashed gray frame margins and columns, row and column guides don’t control where frame text flows. PagePlus represents rows and columns on the page area with dashed blue guide lines. You also have the option of setting up row and column guides as an underlying layout aid. If you like, you can set the margins to match your current printer settings. The page margins are shown as a blue box which is actually four guide lines-for top, bottom, left, and right-indicating the underlying page margin settings. Page margin settings are fundamental to your layout, and usually are among the first choices you’ll make after starting a publication from scratch. They can include page margins, row and column guides, bleed area guides, and ruler guides. This suggests that breathing-induced motion should be accounted for separately, with the breathing margin added linearly to the quadrature sum of the other contributing errors.Layout guides are visual guide lines that help you position layout elements. Applying this relation to realistic breathing models results in a dose distribution in which the sharp edge of the step function is still evident even after blurring caused by the motion. This paper shows that the blurred dose distribution D(z) arising from a step function beam edge that is moving cyclically along the z-axis is given by D(z) = 2t/tau, where t(z) relates time to position and tau is the cycle duration. This approach is satisfactory when the probability distributions of the component errors are Gaussian, but breathing-induced motion of the CTV is generally not Gaussian. The width of the margin is commonly based upon the quadrature sum of the standard deviations of the contributory errors. Geometric uncertainties in radiotherapy treatment may be accommodated by drawing an adequate margin around the clinical target volume (CTV).
