TARGATORLE(1) 1 (July 12, 1991) TARGATORLE(1)
NAME
targatorle - Convert Truevision TARGA images to RLE format.
SYNOPSIS
targatorle [ -h headerfile ] [ -n nchannels ] [ -o
outfile.rle ] [ infile.tga ]
DESCRIPTION
Targatorle converts a file from Truevision's TARGA format
into RLE format. If no input file is specified, the data is
read from stdin. Targatorle recognizes (but cannot
necessarily process) all of the image subtypes defined by
the 1989 TARGA 2.0 specification:
0 - Header Only, No Image Data
1 - Uncompressed, Color-mapped Image
2 - Uncompressed, True-color Image
3 - Uncompressed, B/W (gray scale) Image
9 - Run-length encoded, Color-mapped Image
10 - Run-length encoded, True-color Image
11 - Run-length encoded, B/W Image
Targatorle should correctly process images in formats 0, 2,
3, 10, and 11. No support is currently available for color
mapped images.
OPTIONS
-h Allow the program to write TARGA header information to
headerfile
-n where nchannels is 3 or 4. If input is a color image,
copy only nchannels of the TARGA file; this allows the
alpha channel to be stripped. By default, the alpha
channel will be copied if present.
-o Use outfile as output instead of stdout.
LIMITATIONS
The TARGA image descriptor byte is ignored; therefore, the
image origin is assumed to be that of RLE(5) (bottom left).
None of the color-mapped TARGA formats (types 1 and 9) are
supported. Finally, no attempt has been made to support
extensions to the TARGA File Format introduced by Truevision
in 1989 (new support for time stamps, comments, user-defined
data fields, etc.).
