Thanks for your patience during our recent outage at scalar.usc.edu. While Scalar content is loading normally now, saving is still slow, and Scalar's 'additional metadata' features have been disabled, which may interfere with features like timelines and maps that depend on metadata. This also means that saving a page or media item will remove its additional metadata. If this occurs, you can use the 'All versions' link at the bottom of the page to restore the earlier version. We are continuing to troubleshoot, and will provide further updates as needed. Note that this only affects Scalar projects at scalar.usc.edu, and not those hosted elsewhere.

To annotate an image, you must be logged in with Author privileges for the Scalar book containing the image. Navigate to the image in Scalar, and click the annotation icon (paperclip) in your Scalar header bar. This will launch the annotation editor. Once in the editor:
Click and drag your cursor across the image, drawing a rectangle around the area you wish to annotate.
Enter the title of the annotation in the field just below the rectangle.
Click "Save."
Alternatively, instead of drawing out a rectangle, you can click the + sign at the bottom of the annotation editor and manually enter the coordinates and width and height for the annotation.
You should now see the Title, the X and Y coordinates and the Width and Height for the annotation in the annotation editor. You can now adjust the annotation's area and coordinates by modifying the values in the X, Y, Width and Height fields.
Enter the content of the annotation (optional).
Enter an abstract for the annotation (optional).
Click "Save" at the bottom of the annotation editor.
You can also click any annotation in the annotation list on the left to select it. Selected annotations can be edited using the provided form, or deleted by clicking the minus button. When you're done editing annotations for the file, click "Done" to return to the page for the media file.
