Viewer Pane

The Viewer Pane is an integrated image and document viewer that can be displayed within the Lister. When it is enabled, it will automatically show (if possible) the contents of the most recently selected file. It provides a very quick way to preview files - simply navigate to the folder in question, and click on the file to show it. Using the cursor keys you can easily move up and down a list of files, viewing them as you go.

The easiest way to display the Viewer Pane in a Lister is with the button (Viewer Button.png) on the default toolbar. You can also press F7.

With the viewer pane displayed, viewing a file is as simple as selecting it in the file display. Opus can natively show many types of image files, and comes with plugins to display common document formats like Word and PDF files (providing suitable viewers are installed in the system). The title bar of the viewer pane displays the name of the currently viewed file, as well as some information about it - if it's an image format, it will generally display the resolution and type of image. For files that require the use of a plugin, the name of the plugin will generally be shown.

There are a number of buttons in the viewer pane's title bar:

 

Using the mouse wheel over the viewer pane will move images and documents up and down (where applicable, and assuming third party viewers don't use the wheel for something else). Holding the Alt key also allows you to scroll left and right with the mouse wheel with Opus's built-in image viewer and plugins that support it.

 

There are a number of options on the Viewer / Viewer Pane page in Preferences that let you control the appearance and behavior of the viewer pane. One of them, Show control bar, lets you enable an additional toolbar at the bottom of the viewer pane.

Many of the functions accessible from this toolbar are the same as those in the title bar (although the buttons are bigger, and thus easier to click!) - the buttons are Previous File (Viewer Control - Prev.png), Next File (Viewer Control - Next.png), Rotate Left (Viewer Control - Rotate Left.png), Rotate Right (Viewer Control - Rotate Right.png), Zoom In (Viewer Control - Zoom In.png), Zoom Out (Viewer Control - Zoom Out.png), Original Size (Viewer Control - Original Size.png), Fit To Page (Viewer Control - Fit To Page.png) and Grow To Page (Viewer Control - Grow To Page.png). The remaining buttons are:

 

Depending on the plugin (if any) used to view a particular file, not all of the above functions may be supported. For example, some plugins may not support rotating the display, and in this case the rotate left and rotate right functions would be unavailable.

The viewer pane also has a context menu - although this too can vary depending on the plugin - accessed by right-clicking on the currently displayed image.
