Description:

The Photon image viewer displays bitmap image files on the Photon workspace. When you first start the viewer (without specifying an image filename), you'll see a File menu and an empty image area.

The File menu provides a File Selector mechanism for loading image files.

For more information about capturing screen images, see snapshot.

Examples:

Run pv using the Photon server on node my_node:

pv -s/net/my_node/dev/photon

Run pv at initial position (10,10) with initial dimension of 200*300:

pv -x10 -y10 -h200 -w300
