TARGATORLE(1)TARGATORLE(1)NAMEtargatorle - Convert Truevision TARGA images to RLE format.
SYNOPSIStargatorle [ -h headerfile ] [ -n nchannels ] [ -o outfile.rle ] [
infile.tga ]
DESCRIPTION
Targatorle converts a file from Truevision's TARGA format into RLE for‐
mat. If no input file is specified, the data is read from stdin. Tar‐
gatorle 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 header‐
file
-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, com‐
ments, user-defined data fields, etc.).
