Content
We make a variety of content available to you to use with this assignment.
This document describes the content we have assembled and gives you some
information about how to make your own content if you wish to do so.
Provided
We provide you with a variety of images and animations for this assignment.
Images are all stored in TIFF format; to view the images, use the xv
or display program. The animations are in QuickTime format and
can be viewed on SGIs with movieplayer.
See the directory /usr/class/cs248/assignments/assignment2/content

Making your own
If you wish, you
can try making your own images or movies and using them in the video
editor. Images must be in TIFF format; you can covert other formats to
TIFF using convert. convert takes two command line
arguments: the name of the original file and the name of the new file; it
examines the file suffixes to determine which type the files are:
% convert bjork.jpg unbelievable.tif
Converting animations is more difficult; read the man pages for
dmconvert and moviemaker.
Note that the effects system isn't designed to be robust about handling
images of varying sizes; if you're combining many different images
together, make them all have the same resolution before loading them into
the effects sytem. To resize images, run display image.tif, click
the left mouse button on the image to get the menu, and select
View/Resize... from the menu. All of the content that we have provided is
320x240 pixels.
