NAME
raw2tiff - create a TIFF file from a raw data file
SYNOPSIS
raw2tiff [ options ] *input.raw output.tif
DESCRIPTION
raw2tiff converts a raw byte sequence into TIFF. By default, the TIFF image is created with data samples
packed (PlanarConfiguration=1), compressed with the PackBits algorithm (Compression=32773), and with each
strip no more than 8 kilobytes. These characteristics can overridden, or explicitly specified with the
options described below.
OPTIONS
-H number
Size of input image file header in bytes (0 by default). This amount of data just will be skipped
from the start of file while reading.
-w number
Width of input image in pixels (can be guessed, see Guessing the image geometry below).
option -b number
number of bands in input image (1 by default).
-d datatype
type of samples in input image, where datatype may be one of:
┌───────────┬──────────────────────────────────┐
│ Data type │ Description │
├───────────┼──────────────────────────────────┤
│ byte │ 8-bit unsigned integer (default) │
├───────────┼──────────────────────────────────┤
│ short │ 16-bit unsigned integer │
├───────────┼──────────────────────────────────┤
│ long │ 32-bit unsigned integer │
├───────────┼──────────────────────────────────┤
│ sbyte │ 8-bit signed integer │
├───────────┼──────────────────────────────────┤
│ sshort │ 16-bit signed integer │
├───────────┼──────────────────────────────────┤

├───────────┼──────────────────────────────────┤
│ float │ 32-bit IEEE floating point │
├───────────┼──────────────────────────────────┤
│ double │ 64-bit IEEE floating point │
└───────────┴──────────────────────────────────┘
-i config
type of sample interleaving in input image, where config may be one of:
┌───────────────┬──────────────────────────────────┐
│ Configuration │ Description │
├───────────────┼──────────────────────────────────┤
│ pixel │ pixel interleaved data (default) │
├───────────────┼──────────────────────────────────┤
│ band │ band interleaved data. │
└───────────────┴──────────────────────────────────┘
-p photo
photometric interpretation (color space) of the input image, where photo may be one of:
┌─────────────┬───────────────────────────────────────┐
│ Photometric │ Description │
├─────────────┼───────────────────────────────────────┤
│ miniswhite │ white color represented with 0 value │
├─────────────┼───────────────────────────────────────┤
│ minisblack │ black color represented with 0 value │
│ │ (default) │
├─────────────┼───────────────────────────────────────┤
│ rgb │ image has RGB color model │
├─────────────┼───────────────────────────────────────┤
│ cmyk │ image has CMYK (separated) color │
│ │ model │
├─────────────┼───────────────────────────────────────┤
│ ycbcr │ image has YCbCr color model │
├─────────────┼───────────────────────────────────────┤
│ cielab │ image has CIE L*a*b color model │
├─────────────┼───────────────────────────────────────┤
│ icclab │ image has ICC L*a*b color model │
├─────────────┼───────────────────────────────────────┤
│ itulab │ image has ITU L*a*b color model │
└─────────────┴───────────────────────────────────────┘
-s swap bytes fetched from the input file.
-L input data has LSB2MSB bit order (default).
-M input data has MSB2LSB bit order.
-c Specify a compression scheme to use when writing image data: -c none for no compression, -c
packbits for the PackBits compression algorithm (the default), -c jpeg for the baseline JPEG
compression algorithm, -c zip for the Deflate compression algorithm, -c lzw for Lempel-Ziv &
Welch.
GUESSING THE IMAGE GEOMETRY
raw2tif can guess image width and height in case one or both of these parameters are not specified. If
you omit one of those parameters, the complementary one will be calculated based on the file size (taking
into account header size, number of bands and data type). If you omit both parameters, the statistical
approach will be used. Utility will compute correlation coefficient between two lines at the image center
using several appropriate line sizes and the highest absolute value of the coefficient will indicate the
right line size. That is why you should be cautious with the very large images, because guessing process
may take a while (depending on your system performance). Of course, the utility can't guess the header
size, number of bands and data type, so it should be specified manually. If you don't know anything about
your image, just try with the several combinations of those options.
There is no magic, it is just a mathematical statistics, so it can be wrong in some cases. But for most
ordinary images guessing method will work fine.
