Description: You select an image, and it's shown re-sized to almost exactly fit one-inch cell-phone screen. You then issue commands to cut off (crop) a section at the top/bottom/left/right, and it shows the resultant smaller part of the image re-sized again to almost exactly fit the screen. The idea is to select a small part of the original image, such as the person's face, and fill the whole screen with just that part, to make that part easier to see.
Before running the demo yourself, you need to contact
Robert
to get a guest password. Then you may try
demo-version 1
which has a canned radio-button list of starting images, and always works
from a 1/8-scale degraded version, and doesn't provide any way to either see
your final product with correct aspect ratio nor to save your final work
for permanent reference. But it *does* show how the interactive successive
cropping commands work.
Update 2010.Jul.07:
demo-version 2 is available only when supervised by Robert. It works from whichever
version (original, or degraded 1/2 1/4 1/8 1/16 ...) best matches cell-phone
size, thus allows zooming in on the finest detail available in the original
image. Otherwise it's the same as demo version 1. Unfortunately, if you
play with several large images, it fills up all the free space on my Unix
shell account and I need to purge before doing anything else.
Update 2010.Sep: With my disk almost entirely full, I had to stop running these demos, and then 2010.Nov I moved the largest of the original images to other sites to free up 80MB of disk space, so these two demos probably wouldn't work any more until I modify them to be able to find where the original images have moved to and go fetch whichever of them are needed for the current demo, then automatically purge them again when disk space gets too full again.
