It is possible to add multiple Viewer nodes, though only the active one (last selected, indicated by a red header) will be shown on the backdrop or in the Image editor.

Utilisation de l’Éditeur Image

The Viewer node allows results to be displayed in the Image Editor. The image is facilitated in the header by selecting Viewer Node in the linked Image data-block menu. The Image Editor will display the image from the currently selected Viewer node.

To save the image being viewed, use Image ‣ Save As…, Alt-S to save the image to a file.

The Image Editor also has three additional options in its header to view Images with or without Alpha, or to view the Alpha or Z itself. Click and holding the mouse in the Image displayed allows you to sample the values.
