This directory includes a number of shell scripts which use Utah Raster
Toolkit commands to do various things.

cmaptorle:
   This command take an ascii colormap file as input and creates a URT
   image of that file.  Example: cmaptorle cmap | get4d

graytoabekas:
pseudotoabekas:
rgbtoabekas:
texttoabekas
   These are sample scripts that can be used to send raw image data to
   the Abekas A60.

rainbow
   This command applies a colormap file to a white URT image (sort of).
   It is best to explain by example.  Try this:

   texttorle Times-Roman 40 255 255 255 Hello >text.rle
   rainbow cmap text.rle | get4d

spin
   This command will take a URT image and spin it 360 degrees, creating
   a series of URT images in one file.  Try this:

   texttorle Times-Roman 40 255 255 255 Hello >text.rle
   spin text.rle
   getx11 -m text-spin.rle

urtfade:
   This script is used to generate a 30 frame transition between two images
   of the same size.

tontsc.urt:
   This command is used to scale an image into a variety of image formats.
   I use it mostly to scale image data into a 720x486 format (NTSC).  I
   have added a number of other "standard" size options to it (they are
   easy to add).


You may wish to copy these tools to a directory (like /usr/local/bin) in
your path.  To see more details on how these commands are used, look in
the man directory.
