TNIMAGE.NEW
You may be interested to know that TN-Image now has its own
full-time anonymous ftp site. The address is:
ftp://las1.ninds.nih.gov/pub/dos
ftp://las1.ninds.nih.gov/pub/unix
At these sites, you can find the latest shareware version of TN-Image,
as well as a variety of test images, and other programs, including:
TNSHELL - A menu-based DOS shell with built-in text editor,
password protection, screen blanking, calculator,
multi-function alarm clock with separate messages
for each alarm, the ability to execute commands or
sound alarms at specified times, and many other
features. In contrast to other DOS shells, TNSHELL
only ties up about 100 bytes when it executes a
program. TNSHELL can also associate any command with
any filename, so you can simply click on a text
file (for example), and TNSHELL can execute the word
processor and load the file or files automatically.
NPLOT - A powerful spreadsheet/ mathematical analysis/
scientific graphics plotting program. Plots
publication-quality graphs or drawings on a pen
plotter or printer, performs FFT, peak
detection, non-linear regression to an arbitrary
user-specified equation or one of several built-in
equations, performs matrix math, has a powerful
macro language allowing you to apply any arbitrary
vector function to the data, and numerous other features.
Creates images readable by TN-Image.
To access, type:
ftp las1.ninds.nih.gov
Log in as "anonymous". Enter your e-mail address
as a password. Then type the following sequence of
commands:
cd pub/dos
cd tnimage
binary
ls
get <filename>
bye
If you have trouble logging on to the ftp site, try
ftp://las2.ninds.nih.gov instead.
If you do not have ftp access, write to the above address and we
will send you a registered version of TN-IMAGE or NPLOT for US $25,
or a registered version of TNSHELL for $15. (Please add $5 for
foreign orders). Shareware versions of these programs are also
available on Compuserve and on many archive ftp sites.

*******************************************************************
NEW FEATURES IN TN-IMAGE - SEE MANUAL FOR DETAILED DESCRIPTIONS
*******************************************************************
NOTE: The command line options have been changed since version 1.10.
Most options now must be prefaced with a "-", for example:
tnimage -vesa -mode 103 .
This allows you to specify filenames on the command line.
See Manual for details.
03-15-1997 (Version 2.50)
X window icons and resource handling added.
Option for loading each image in a separate window. Portions of an image
can still be cut/pasted onto other images, even if they are in separate
windows.
Improved handling under mwm and olwm.
02-22-1997 (Version 2.40)
HP scanner support added (Unix versions only)
Improved macro editing.
02-15-1997 (Version 2.30)
UNIX versions for SGI, Solaris, Linux, and ConvexOS released.
New math functions and calculations using data from other images
added to image math.
3D image support added.
12-01-1996 (Version 2.23)
Fixed problem with PostScript printing. Images wider than the
screen would contain an image of the palette if it was being
displayed.
Changed dialog options for PostScript to allow the y/x ratio
to be adjusted.
Various performance improvements.
Minor bug fixes and clarifications of the documentation.
Fixed bug which caused extraneous pixels in 24 bit/pixel screen
modes on ATI Mach 64 cards.
XGA Microchannel support added.
Fixed handling of 16 bit grayscale images (Printer output on
PCL printers would be solid black if grayscale mapping was set
too high; in densitometry, it was impossible to set background
above 255; 16-bit TIFF files were not automatically recognized).
PCL printer output is now gamma corrected.
Development of DOS version discontinued.
04-01-1996 (Version 2.20)
User-selectable cursor type.
03-15-1996 (Version 2.19)
"Paint" and "Fill region" options now remain in effect until
explicitly deactivated.
Areas calculated in strip densitometry are now reported
in terms of calibrated distances instead of raw pixels.
Images can now be resized by click-and-dragging on the lower right
corner.
Minor bug fixes.
02-15-1996 (Version 2.18)
Added creation of raw ASCII and raw byte files.
Added ability to load a Fourier-transformed image. (The header on
old-style FFT files must be changed before they can be read. See
manual for details).
Added movable window to display Real and Imaginary values for each
coordinate of a FFT'd image.
Contrast and pixel math functions now have better control in
changing FFT values.
02-01-1996 (Version 2.17)
PostScript printing added.
Added ability to redirect printing to a different printer or a file.
Initialization file is now editable.
01-01-1996 (Version 2.16)
Version 0.01 (beta) for Linux available.
Improved macros so that raw byte images can be loaded with a macro.
Added more defaults to custom file format to permit creation of
custom file formats with only raw bytes.
Added interactive color adjustment of 8-bit images. The color balance
of low-end images such as GIFs can now be adjusted without converting
them to 24 bits/pixel. The original intensity adjustment was renamed
to "Change pixel value" to more accurately reflect its function.
8-bit images (such as GIFs) can now be filtered without first
converting them to 24 bits/pixel.
In high-color and true color screen modes, the red, green, and blue
color planes can now be isolated. Operations such as filtering,
copying, etc. can be applied to any combination of color planes.
For example, it is now possible to filter the blue colors in an
image, leaving the red and green untouched.
GIF files with invalid color palettes are automatically repaired.
It is no longer necessary to repair them manually. The option "read
entire palette" has also been removed.
"Restore image" also restores the original color palette.
Reorganized menu structure.
When converting images to different depths, the title and other data
are now retained.
Bug in horizontal and vertical flipping of images fixed.
Changed frame-rate testing to make it more accurate and easier on
the eyes.
11-01-1995 (Version 2.14)
Horiz. and vertical flipping is now faster.

on the palette bar (pseudocolor modes only).
Increased speed of the most common filtering operations (up to 4x
faster).
Selected area is now outlined by a "crawling box".
A status box is now visible to indicate which state the program is
in (densitometry, sketch mode, etc). Clicking on this box deactivates
the mode.
08-01-1995 (Version 2.12)
Measurement of angles added.
2D Calibration mode added.
Distance measurement now reports in terms of calibrated distances
instead of raw pixels.

Fixed a problem with image not getting the new quantized palette after
an image was converted from 16 to 8 bits when TN-Image was in a 16 bit
screen mode.
Speed enhancements for filtering (16-54% faster), and contrast,
pixel math, and color/brightness adjustment (50 to 166% faster).
Added ability to shell to DOS or execute a command.
Program now asks if you want to save an image that has been modified.
03-18-1995 (Version 2.05)
Creation of custom file formats has been improved.
TN-Image can now "learn" to automatically recognize, create, and
correctly display almost any uncompressed raster file format.
Fixed filtering of medical grayscale images (occasionally would
inappropriately set a pixel to white).
02-01-1995 (Version 2.02)
Added reading and writing of Jpeg, TGA, and Windows BMP formats.

minor bugs including bug in changing the image size if no images
are present.
XOR'ing, addition, subtraction, etc. of multiple images is now easier
to use.
Completely rewritten memory management to fix some bugs. Previously
it was sometimes possible to completely fill memory with images,
making it impossible to display the dialog box necessary to save
the image.
Menus are now accessable by Alt+key combinations as well as by the
mouse.
Fixed 800x600 display problem at 24 bpp on ATI and other cards which
split pixels across banks.
Creation of CMYK custom images is now possible.
Palette display is now available in color modes.

details about each image, its location, size, and filename.
Support for GEM IMG files and files from IBM MVS.
07-01-1994
Automatic and manual subtraction of baseline from scanned areas.
Automatic peak detection and integration of scanned areas. This
feature makes "scanning" an area of the screen more suitable for
quantitation than "densitometry" in many cases.

within TN-Image or saved to disk as an ASCII file.
File list allows you to select a file, change drives, and change
subdirectories from a menu instead of typing the filename.
Smoothing of profiles of scanned regions.
Scanned region profiles may be saved to disk or captured as a
new image.
06-01-1994
Scanned regions are plotted on the screen. Area of any region
of the curve can be measured by clicking-and-dragging.
Pressing <Enter> or <Esc> is now the same as clicking "OK" or
"Cancel" in all message boxes.
Added support for certain unconventional VESA cards and lower
resolution screen modes, down to 640x400.
