Using the Image Viewer

The image viewer enables you to view a high resolution image in its own resizable window. It it possible to open multiple images by opening multiple windows.

You can open an image by clicking on its thumbnail. Thumbnail images are associated with image series. You can navigate to them by finding a gene and either choosing to compare several of its image series, or select one of its experiement's details and click on the link to view its images.

Ways to interact with an image include:

• Drag the image with your mouse pointer to an area of interest, then click to zoom in.
• Drag the red boundary box in the thumbnail window to manipulate the image.
• Use the toolbar at the bottom of the viewer window to pan to an area of interest and zoom in or out
• The context menu is available by right-clicking (or Control-clicking for Mac users) anywhere in the window
• Use the drop-down list at the top of the window to view a different image from the same series, or to retrieve additional information.

Using the Toolbar

The following table describes the function of each button on the Single Image Viewer toolbar:

Button	Function
	Quick zoom slider (move horizontally to zoom in or out)
	Zoom in
	Zoom out
	Pan image left
	Pan image up
	Pan image down
	Pan image right
	Reset image to default state
	Display additional features that are otherwise available via a context menu. See the following section, "Using the context menu" for more information about this menu and the features that it exposes.

Using the Context Menu

A context menu augments the features made available by the toolbar in the Image Viewer window. Expose the context menu by right-clicking from a Windows PC or Control-clicking from a Mac. Alternatively, most of the context menu features are also available by clicking "More Tools" on the Image Viewer toolbar.

Use the context menu to:

• Zoom all the way in on a specific point in the image.
• Switch between expression and ISH views (ISH is the default view).
• View the Reference Atlas for the image (or switch back to the ISH view).
• View information about the image's series in a new window.
• Share the image with someone via email (this generates a hyperlink that takes the recipient to the image in the Single Image Viewer at the same zoom level and position).
• Display the Drawing Tool, which allows you to draw and add text to an image. See "Using the Drawing Tool" for more information.
• Print the image. See "Printing an image" for specific printing instructions.
• Show or hide elements of the Single Image Viewer such as the toolbar, image name, and the image slice navigator (select Image Viewer Setup...).
• Download the image as a JPEG.

Printing an Image

When you print an image from the Single Image Viewer, the image in the printout will appear as it does on the screen. Not only do drawings and/or text appear in the printout, but interface elements such as the Drawing Tool, the image name (which you can move by clicking and dragging) and the toolbar also appear.

To expose or hide interface elements before printing, select "Image Viewer Display Setup..." from the context menu selecting the elements you want to appear.

Printing tips:

• Restrict the range or pages to the first page only (the second page is blank).
• Select Landscape for the print orientation.
• You may have to set the printer properties so that the image stretches to fit the page. Properties vary by printer, so finding the optimum settings may require some experimentation.
