| NCSA Astronomy Digital Image Libary Help: Movie Page | ||
Currently, not all image cubes have a browsable MPEG movie associated with them. Those images that do have browsable movies available will feature a "Movie Page" button in its Preview Page.
Browsing as an MPEG movie
When you browse an image cube as a movie, you will see each plane in
the cube in succession. If the field in this section labeled "Movie
file status" is marked as "retrievable", then you can click on the
"Download MPEG movie" to download the sequence.
To view the movie, you must have an MPEG player installed on your local machine (such as mpeg_play for X-window platforms). Users may find more sophisticated MPEG views that allow for stepping through a movie particularly useful; in lieu of that, X-windows users might like to use the X Play Gizmo control panel as a wrapper around their MPEG players.
Browsing Selected Planes From The Image Cube
With the form provided, you can specify specific planes of the cube to
preview and have them tiled within your Web browser. To do so, enter
plane numbers into the imput field as a comma seperated list. A range
of planes may be specified by the first and last plane numbers
seperated by a colon. After entering you request, hit the "Retrieve
Preview Images" button, and you will (eventually) see your requested
images tiled within your browser window.
You enter You will see planes numbers 1,4,7,10 1,4,7,10 5:9 5,6,7,8,9,10 1,3,6:9,15 1,3,6,7,8,9,15NOTE: Requesting a large number of images can sometimes take several minutes to retrieve (on the server side) and download (to the client side).
