DTA (Dave's .TGA Animation Program)
Rel 2.0.8 (10/23/93)
Copyright (c) 1991, 1992, 1993 by David K. Mason
DTA is a command-line utility for creating Autodesk Animator .FLI
and .FLC animation files from:
o .TGA files as created by the POV-Ray and POLYRAY ray-tracers.
o .IMG files as created by the Vivid ray-tracer.
o .PCX files.
o .GIF files.
o Other .FLI or .FLC files.
o Presidio .ANI animation files
DTA can also perform a wide range of post-processing functions
on image files including:
o Creating a single optimal 256-color palette from a series of
truecolor pictures, and then creating an Autodesk Animator .FLI
file out of them.
o Rescaling.
o Multi-layer compositing.
o Saving the palette as a .COL file, readable by either Autodesk
Animator or the TGAFLI animation utility.
o Saving the palette as a .MAP file, readable by the PICLAB and
IMPROCES image processors, and the FRACTINT fractal generator.
o Reading in a palette file in either .COL or .MAP format
and animating a bunch of pictures using that palette.
o Animating a bunch of pictures using grayscale.
o Convert pictures to .GIF, .TGA, and graycale .TIF files.
o Averaging images together for a variety of effects, including
simulated motion blur and red/blue 3D.
o And more.

**** IF YOU ARE HAVING MEMORY PROBLEMS WITH DTA, READ THIS ****
Real mode vs. Protected mode:
DTA used to come in two varieties: a real mode version and
a protected mode version. From now on there's only a
protected mode version. There's no more DTAX.EXE.
DTA will let you access up to 16MB of extended memory (either raw
or configured as XMS with HIMEM.SYS or QEMM386.SYS or whatever).
It requires at least 1 or 2 MB of RAM to run at all.
Don't delete the files DPMI16BI.OVL, RTM.EXE, and DPMIINST.EXE.
These make up the protected mode drivers for Borland Pascal 7.0
(the compiler used to build DTA). DTA won't run without them.
----------------------------------------------------------------------
The Rules:
Feel free to re-upload this program to other bulletin board
systems in its *original, unmodified* form. You may not
repackage it with other programs. You may not repackage it with
your own tutorial. I feel like an idiot having to make these
demands, but I've been finding archives on BBSs going by
names like MORPHPAK.ZIP which are collections of DTA, my other
program DMorf, sometimes also Richard Godoeken's program
RMORPH, plus Trilobyte's PLAY. That's not kosher. I and those
other folks distributed our programs the way we did for
reasons.
Do not include this program on a disk along with any magazine,
book, hardware product, or other software product without my
permission.

----------------------------------------------------------------------
Switches:
(Output options)
/O[name] Specify an output filename.
/FF Create a .FLI animation file. [default]
/FM Create a PICLAB .MAP palette file.
/FC Create an Autodesk Animator .COL palette file.
/FG Create .GIF file[s].
/FT Create new .TGA file[s].
/FI Create grayscale TIFF files
(Targa Output options)
/NC Do NOT compress .TGA file
/B## Number of bits per pixel in TGA ( 8/16/*24*/32 )
or FLIC (*8/16). (If you specify /b16 for a flic
you'll get a Tempra FLX instead of a FLI or FLC.)
(.FLI output options)
/P Play in ping-pong, or pendulum, oscillation order.
/Snnn Specify display speed of animation playback (default=0).
/R[#] Specify resolution:
1 = 320x200 [default]
2 = 320x240
3 = 320x400
4 = 320x480
5 = 360x480
6 = 640x480
7 = N/A
8 = 800X600
9 = N/A
10 = 1024x768
11 = N/A
12 = 1280x1024
/RA Base resolution on the size of the first input
file.
(Palette options)
/G Use 64-level greyscale instead of a palette.
/G32 Use 32-level greyscale insted of a palette.
/332 Use 3/3/2 palette.
/Upalname Use existing .MAP or .COL file for palette.
/M# Set maximum internal colors.
/MN Do NOT remap colormapped input.
/PO Force single optimal palette generation even when
creating GIF files.
/C# Scan only one frame per # for palette.
(Dithering options)
/DF Dither with Floyd-Steinberg filter.
/DS Dither with Sierra-Lite filter.
/DO[1-6] Ordered dither (digit represents dither strength).
/DR# Random noise dither (digit represents dither strength).
(Other options)
/L Separates output layers. Picture files specified
in later layers get overlayed on top of previous
layers. If the overlayed pictures contain transparency
informations (32-bit TGA files only), then the
pictures underneath will show through.
/K# Use only one frame per # picture files. Skip the rest.
/3D Create red/blue 3D picture.
/A[#|A] Average <number> TGAs per output frame (A=All).
/T[#|A] Trail <number> TGAs per output frame (A=All).
/X[num] eXpand <number>. Create and insert <number> averaged.
frames between each pair of regular frames.
/GA# Gamma-correct picture. Try specifying a number
between 1.0 and 2.0 to brighten, between 0.5 and
1.0 to darken.
/SC[#,#] Rescale pictures to screen resolution.
/CL[#,#,#,#] Clip the input picture. The first two numbers
specify the top-left, and the other two numbers
control the width and depth.
/CH#,#,# Chroma-key, to make all occurrences of a color
transparent for compositing. The three numbers
represent the red,green, and blue components
of the key color.
/CT# Chroma-key tolerance. Specifies how close to the
key color a pixel has to be to make it transparent.
