A great presentation begins with a pleasing and well thought out slide design. You also need consistency between your slides, elements that fit them together. In LibreOffice, you can use the Master Pages to create the base design for your presentation. Master Pages become the framework for the entire presentation, binding the elements of our presentation together. Much of this is accomplished through styles, and Master Pages are the main style. You can think of Master Pages being equivalent to Page Styles in Writer.
Editing Master Pages
To edit master pages, you must switch to the Master View. Start Master View through View > Masters > Slide Master. Alternatively, you can right-click the master page you want to edit in the Master Page section of the Tasks pane, and select Edit Master.
When you enter Master View, the master toolbar appears. The master toolbar gives you options specific to editing master pages. Use add to add a new master page. Delete allows you to delete the selected master page. Delete is grayed out when you have only one master page, because you must have at least one. Rename lets you rename the currently selected master page, and Close Master View exits master page editing.
You have five predefined editable areas in a master page:
Title Area – The title area contains the title of the slide. Think of it as the subject of the slide.
Object Area – The object area contains the data of the slide, whether it is text, an image, a chart, or a table. As you will learn, the data of the slide is not confined to the object area. You can add elements outside the object area, but it's a good idea to keep data generally in this area for consistency in your presentation.
Date, Footer, and Slide Number Area – By default, these areas do not show up on the actual slide. To change, go to View > Header and Footer, and you can change whether or not these objects will appear on the slides.
Modifying the Master Page
We will start with the default style for your master page. First, let's change the background. Format > Page. On the background tab, use the dropdown box and select gradient. In the gradient list, select Radial red/yellow. Click OK. This gives you a bright, sunny background to work on.
NOTE: You can download the icon graphic used in this tutorial at http://eeperry.co.cc/resources/modules.png.
Next, we will add a graphic to your master page. The graphic will show up on all slides that use this master page. I created a ribbon graphic containing the icons for all the LibreOffice applications. We want it to sit just below the object area. Insert > Picture > From file. Select your picture and Open. Move the image to the position you want it, just below the object area. You want the image centered at the bottom. Rick-click the image and select Alignment > Centered. You also want the image to appear behind any objects which might go over it. Right-click the image again, and select Arrange > Send to back.
Now, let's add a line under the title. Select the line tool from the drawing toolbar at the bottom of the window, and draw a line under the title area. You can change the line style using the line toolbar. Change the style of the line, the thickness, color, and the start and end arrow styles.
Finally, let's edit the date, footer, and slide number areas (below). While in Master View, you can change the size and placement of these objects, but actually filling them with content can be done at any time. View > Header and Footer. On the slide tab, there is a checkbox for each of the three areas: date, footer, and slide number.
Under date and time, you can choose a fixed date or a variable date. You can use fixed date when you have a presentation that is presented one time, or you want the date to appear in a non-standard way. Place your date text in the textbox beside the variable selection. What you place in the textbox is what will show in the date textbox on the slide. Use variable date when a presentation date is unknown, or you will give the presentation more than once. Variable will place the current date in the date textbox. With variable, you need to select a format in the dropdown. You can also change the language.
For the footer area, you type the text you want in the footer area in the textbox. Whatever you type in the textbox appears in the footer area.
There's not much to the slide number. You either check it to show or not show. When checked, the slide number will show up in the slide number area.
NOTE: The date, footer, and slide number areas are disabled on the first slide, the title page.
Click the Apply to All button to apply the settings to all the slides except the title page. Click the Apply button to apply it to only the current slide.
Impress Styles
Just like in Writer and Calc, Impress can use styles to keep everything uniform. Styles are also a time saver. However, styles are a little different in Impress. Impress only has two different style types, Presentation and Graphic.
An easy way to think about presentation styles is as the styles related to the master pages. You have styles for backgrounds, background objects, outline text, notes, titles, and subtitles. You can modify these styles any way you want. However, you cannot create new presentation styles.
Graphics styles are styles for objects and text not directly related to the master pages. You can modify these styles in any way you want, and you can create new ones.
Editing of styles is done from the Styles and Formatting dialog. You can open the Styles and Formatting dialog by clicking on the button in the line and filling toolbar, pressing the F11 key on the keyboard, or by going to Format > Styles and Formatting.
Let's do a couple of modifications to the presentation styles to show how they work. First, enter master view mode, View > Master > Slide Master, and open the Styles and Formatting dialog, Format > Styles and Formatting. Right-click Title in the dialog and select Modify. On the font tab, select a suitable serif or slab font. Maybe make it bold. Switch to the area tab and change the fill to gradient. Select the first gradient in the list (black to white). On the transparency tab, switch the mode to transparency and the percentage to 50%. Click OK, and you will see the font for the title has changed and it has a semitransparent gradient background.
Now, select Outline 1 in the Styles and formatting dialog. Right-click and modify. All we want to do here is change the font. Click OK. Switch to Master View and you will notice that the font is changed for all the outline levels. This is because each of the outline levels links to the previous one. You can't change the linking, but you can change each of the levels to be different. This cascade effect can be useful, especially with the font in helping to create uniformity.
In this how-to, we learned about creating and modifying master pages in Impress. Master pages are key to helping create consistency in your presentation. We also looked at presentation styles and how they help create the style for your slides. I encourage you to play around with the master page settings and presentation styles. The presentation styles have 14 different tabs, making them very flexible. You can create a very professional and visually appealing presentation with these tools.
Next time, we will begin work with individual slides.
