Split View

[BioPharma] [Research+]

Split View allows multiple images to be opened simultaneously in the Viewer. Each image is confined to a dedicated panel within the viewing area and retains all the usual capabilities that are available when viewing a single image (e.g., annotating, panning, and zooming). Various layout options, such as side-by-side, vertical stacks, and 2-D grids, are available to aid the comparisons, as well as a range of functionality for image synchronization and panel management.

Viewing Multiple Images

Split View can be activated from various areas in the application; in general, wherever it is possible to select multiple images. Any tables that support right-click context menus will provide options for launching the Viewer with multiple images simultaneously. For instance, the Folder Listing table in the Repository, the Search Results table, and the Viewer's Browse Folder Panel can be used to select and view multiple images.

Activating Split View from outside the Viewer will result in a 2-D grid layout with the most compact square dimensions for the number of images selected (e.g., 1x1, 2x2, 3x3, etc.). To have more control over image layout, activate Split View from the Viewer's Browse Folder Panel.

To display the context menu on a mobile device, tap and hold on an item.

    • Side-by-side will create a single row of images
    • Stacked will create a single column of images

Panel Layout

When viewing multiple images, the Viewer is divided into a 2-D grid with rows and columns. By default, the grid is regular and each panel (or cell) has the same size. The grid layout can be customized to create an irregular grid, where a panel can span multiple rows and/or columns. There are convenient options for creating three types of regular grids: side-by-side, vertically stacked, and 2-D grid.

To change the number of rows or columns

  1. Click on the Layout button in the Viewer top bar to display the Layout dialog

  2. From the Rows field, increase the number to append new rows to the bottom of the layout or decrease the number to remove empty rows from the layout

  3. From the Columns field, increase the number to append new columns to the right of the layout or decrease the number to remove empty columns from the layout

  4. (Optional) You can change the Cell Aspect Ratio between Fit, 16:9, 4:3, and 1:1

  5. (Optional) You can adjust the Grid Gap slider to add more separation between the images

To add an empty row

  1. Hover or click on any image adjacent to where you want to add the row, to reveal the toolbar at the top left of the panel

  2. Click on the Expand Toolbar button to expand the toolbar if necessary

  3. Click on the More menu

  4. From the dropdown menu, select Insert Row Above to add an empty row above the current image, or Insert Row Below to add an empty row below it

To add an empty column

  2. Click on the Expand Toolbar button to expand the toolbar if necessary

  3. Click on the More menu

  4. From the dropdown menu, select Insert Column Before to add an empty column to the left of the current image, or Insert Column After to add an empty column to the right

  1. Hover or click on the image you want to span across multiple panels

  2. Click on the Resize handle at the bottom right corner of the image and drag it to expand into panel(s) to the right and/or below the current panel

Panel Aspect Ratio

The aspect of the ratio of the panels can be customized to any of the following values: 16:9, 4:3 and 1:1.

To change the aspect ratio of panels

  1. Click on the Layout button in the Viewer top bar to display the Layout dialog

  2. Click on the dropdown menu next to Cell Aspect Ratio

  3. In the dropdown menu, select the desired aspect ratio

    • Fit will adapt the panels' size to attempt to fit all of them on the screen
    • 16:9 will enforce a 16:9 aspect ratio for the panels, even if scrolling is required to see all rows and/or columns
    • 4:3 will enforce a 4:3 aspect ratio for the panels, even if scrolling is required to see all rows and/or columns
    • 1:1 will force panels to remain square

  4. (Optional) Enable the Maximize Panels toggle to expand all panels horizontally to fill the screen, rather than fitting the largest number of panels on screen at a time. This option is only available when aspect ratio is set to a value other than Fit

Panel maximization can be used to control the width of panels. When Maximize Panels is enabled, panel widths are maximized such that the available width on the screen is fully utilized. As a result of the panel aspect ratio setting, panel maximization may reduce the number of panels that are visible on the screen at one time. When Maximize Panels is disabled, the width of panels are reduced (to a minimum size) to ensure the most number of panels are displayed on the screen at one time (without the need to scroll).

Panel Spacing

The spacing between each panel (i.e., the separation between panels) can be customized.

To change the spacing between panels

  1. Click on the Layout button in the Viewer top bar to display the Layout dialog

  2. Adjust the Grid Gap slider to add space separating the panels

Panel Controls

Split View divides the available on-screen space for the image Viewer into one or more panels, depending on the number of images that have been chosen. While each panel can be independently controlled, only one panel can be controlled at any given point in time.

The selected (controllable) image is denoted with a blue border around its panel and a blue dot adjacent to the file in the Browse Folder Panel of the Viewer. Images that appear in other panels are denoted with a gray dot in the Browse Folder panel.

When the digital zoom is applied as a result of zooming another image in the synchronized set, there is no restriction enforced. In this manner it is possible to attain a digital zoom greater than the 400% limit for a single image.
