About Layers
Layers are available in LibreOffice Draw, not in LibreOffice Impress. Layers allow you to assemble elements on a page that are related. Think of layers as individual workspaces that you can hide from view, hide from printing, or lock.
Layers do not determine the stacking order of objects on your page, except for the \<emph\>Controls\</emph\> layer which is always in front of other layers.
The stacking order of objects on your page is determined by the sequence in which you add the objects. You can rearrange the stacking order by \<item type=\"menuitem\"\>Modify - Arrange\</item\>.
The areas on a layer that do not contain objects are transparent.
LibreOffice Draw provides three default layers:
-
Layout
-
Controls
-
Dimension Lines
You cannot delete or rename the default layers. You can add your own layers by \<item type=\"menuitem\"\>Insert - Layer\</item\>.
The \<emph\>Layout\</emph\> layer is the default workspace. The \<emph\>Layout\</emph\> layer determines the location of title, text, and object placeholders on your page.
The \<emph\>Controls\</emph\> layer can be used for buttons that have been assigned an action, but that should not be printed. Set the layer's properties to not printable. Objects on the \<emph\>Controls\</emph\> layer are always in front of objects on other layers.
The \<emph\>Dimension Lines\</emph\> layer is where you draw, for example, the dimension lines. By switching the layer to show or hide, you can easily switch these lines on and off.
You can lock a layer to protect its contents, or hide a layer and its contents from view or from printing. When you add a new layer to a page, the layer is added to all of the pages in your document. However, when you add an object to a layer, it is only added to the current page. If you want the object to appear on all of the pages, add the object to the master slide ().
