TN-Image Image Analysis Software
Latest version: 2.16
ƒƒƒƒƒƒƒƒƒƒƒƒƒƒƒƒƒƒƒƒƒƒƒƒƒƒƒƒƒƒƒƒƒƒƒ
TN-Image is an advanced image analysis program oriented toward
scientific and technical image analysis and editing.
TN-Image can view, edit, create, annotate, analyze, print, and
interconvert monochrome and color images of unlimited size, from a
variety of sources including TIF (Mac or PC), GIF, PCX, IMG, JPEG,
Targa, and BMP, as well as raw bytes and custom image formats. Images
of any pixel depth from 1 and 32 bits/pixel, and any color type,
including CMYK, true color, and medical grayscale images, can be
viewed, interconverted, analyzed, and exported to PC, Mac, or MVS
systems. For example, you could create a 17 bit/pixel TIF file with
7 bits of red, 6 bits of green, and 4 bits/pixel of blue. Few other
imaging programs are this flexible.
New image formats are easily added. Once a new format is defined,
images in the new format are automatically identified and loaded without
any action on your part. This is especially useful for medical images,
which are unreadable by most other programs for the PC.
Image editing features: cut/paste, warp, undo, rotate, change
brightness or contrast, gradient flood fills, color correction,
and histograms. Superimpose, subtract, add or XOR multiple images.
Add graphic elements such as text, lines, circles, Bezier curves, and
polygons. Up to 512 images of any color depth can be on the screen at
one time. Editing can be done seamlessly across several images, regard-
less of their color depth. For 8-bit images, you can use one of 10,000
predefined palettes or graphically create a new one. TN-Image is menu-
driven and has an extremely friendly graphical user interface. Dialog
boxes and graphs can all be clicked-and-dragged to one side so as not
to obscure the image. Even the top menu bar can be hidden.
Analysis features: linear/log calibration (e.g. for molecular
weight), densitometry, area and distance measurement, automatic back-
ground subtraction, 2D FFT, Fourier convolution and deconvolution of
two images, automatic detection and quantitation of bands, spots,
rectangular areas and arbitrarily-shaped regions, and user-definable
equations for mathematical point-by-point color manipulation. Peak
areas can be measured interactively from graphical plots of density
scans or calculated automatically and saved to an ASCII file. Real or
imaginary components of an FFT can be edited and manipulated like a
regular image, then reverse-transformed, to remove or enhance specific
frequency components in the image. Power spectra can also be viewed.
Images can be resized, flipped, color-remapped, or filtered (with
sharpening, blurring, 3 types of edge enhancement, freeze-fracture
effect (shadow sharpening), background subtract, background flattening
(de-trending), or median filter). Quantitative data and peak area tables
can be exported to an ASCII file with a single mouse click or saved as a
new image. All operations function seamlessly across multiple images
regardless of their color depth. Images can be up-or down-converted
into a different color depth or converted to monochrome. Monochrome
images (such as X-ray, CT, or MRI images) of up to 32 bits/pixel can
be viewed and interactively adjusted to view different intensity ranges.
TN-Image is particularly useful to biochemists and molecular
biologists who wish to analyze SDS gels, blots, and DNA gels. The
blot can simply be scanned in any scanner, then imported as an image
file into TN-Image and labeled, analyzed, quantitated, and printed in
color on a laser or inkjet printer. Printed images and quantitative
results have already appeared in several scientific papers. The print
quality is optimized for high resolution, and gives extremely high
quality output.
System requirements: 80386 or above, DOS, SVGA monitor, mouse,
and at least 4 MB RAM. Handles all screen resolutions in 8,15,16,24,
and 32 bit/pixel modes. Uses up to 2 GB of RAM + virtual memory.
Supports laser and inkjet printers up to 2400 dpi. Can also be run
in DOS box under Windows.
