IMPR Version 1.0
Copyright 1993 by Jim Braatz
IMPR is NOT free software! This program is shareware, so please register it
if you plan to use it regularly. Give it a try for a week and see if you
think it's useful. If it is, then I ask that you register it with the author.
Feel free to copy this software for any friends or user's groups, and upload
it to appropriate BBS and ftp sites. But please keep the entire package,
including doc file and README file, all together.
Why to Register
---------------
Why should you? Well, here are a few reasons: You'll get an updated version
of the software, with many improvements (and no nag screen). If enough people
register, then I'll continue to improve the program and inform registered
users of the new versions. New versions of the software will be made
available to registered users for a reasonable fee. I'll also include several
additional programs and utilities with the registered program which I think
will be of interest to the users. You'll get better documentation of the
programs and the functions, too.
I can make no promises, but some ideas I have for improvements include
a utility to align and coadd several images, a utility to combine images
taken with RGB filters on a true-color display, additional color maps,
improved analysis functions, support for additional image types, the option
to load and save files, a blink comparator, a flat field correction, and much
more. So register and see these improvements on your own version of IMPR!
This program is aimed at a very narrow audience, so I'm depending on
everyone who uses this program to register it. That means you! It's not
that hard to do, it's not that expensive, and it's very worthwhile. So
get to it!
How to Register
---------------
The suggested registration fee is $25. I think this is a great bargain for
this software, of course. If you'd like to contribute more, then please do!
Send the registration fee along with your name, address, type of camera you
use, and type of disk you prefer (3 1/2 or 5 1/4) to:

Include any comments or suggestions for improving the software, and if you
have some great astro images you've taken with your camera that you'd like
to show off, send them too! I'd love to see them!
About IMPR version 1.0
----------------------
This program is intended to be used to display and analyze CCD images. The
program has several functions which relate specifically to astronomical
images, but any type of image can be used. The program requires an
SVGA graphics card. Most brands of SVGA cards should work, but there may be
exceptions. A fast processor will be useful for many of the features, as well.
The contour routine and unsharp mask routines, in particular, will be slow
on 386 16 Mhz systems (for example). The program also requires a mouse -
make sure the driver is installed before you start IMPR.
The program currently can be used with 192 x 165 pixel image files. There is
support for the SBIG ST-4 type image files (.sbi files) and plain 8-bit
images of the same pixel size (.08b files). Images taken with the LYNXX
12-bit camera can be used with IMPR as well, but they must first be converted
to 8-bit images with the utility lynx-8b.exe. In the registered IMPR,
support for the LYNXX images will be included without need for the conversion
utility. If you have a different type of camera, then you can write a
converter to the appropriate type image, or you can write to me. I may have
incorporated it already!
How to Use IMPR
---------------
IMPR is extremely easy to use. To start the program, type:
impr image1 image2
where "image1" and "image2" are the names of your CCD images. For example,
type "impr plane.sbi m42.08b" to use the sample images. If you want to show
only one image, then omit the second argument. If two images are specified,
then the "active" one is selected by clicking on the green box to the right
of the image. All operations then pertain to that image.
Most options work by just clicking on the menu button, but a few require
additional input. For example, to do contrast enhancement, select "Rescale",
and then click the mouse twice on the histogram to set the "black" and
"white" markers. You'll then see the color scale adjust accordingly.
In general, the mouse cursor will turn blue when the program is waiting
for additional input, and a message at the bottom of the screen will help
to lead you through the process. To get a quick zoom of the image, just
click on the image itself. The values of several pixels in the center of the
zoomed box will be shown.
You can't hurt your original image, so experiment with all of the buttons.
There are many filters for enhancing the image, unsharped masks of various
sizes, several viewing options including contour plots, image statistics,
profile plots, merging of the two images, and more.
