Layers in DM
 
DM 2.1 now has the ability to add image layers to any existing image object. The same highlights on the original image will then also display on all of the layers. Users can navigate through layers on a single object display, or open up multiple displays of different layers for comparison. Editors can also layer images of different objects to produce a document that one may "page" through. 

Note: variations of the same image for layers need to be the same pixel dimensions and resolution in order to display with the same alignment with respect to highlights. Editors will need to align such images in advance, prior to adding them to a DM image object.  

Adding Layers:


1. Check out the image you wish to add a layer to
2. Click on the add layers icon (see image below)
3. Choose the image to upload as you would a normal image. Note: images from local uploads, IIIF, or URLs can all be added as a layer
