10
12 raw2tiff converts a raw byte sequence into TIFF. By default, the TIFF
13 image is created with data samples packed (PlanarConfiguration=1), com‐
14 pressed with the PackBits algorithm (Compression=32773), and with each
15 strip no more than 8 kilobytes. These characteristics can overridden,
16 or explicitly specified with the options described below.
17
19 -H number
20 size of input image file header in bytes (0 by default). This
21 amount of data just will be skipped from the start of file while
22 reading.
23 -w number
25 width of input image in pixels (can be guessed, see GUESSING THE
26 IMAGE GEOMETRY below).
27 -l number
29 length of input image in lines (can be guessed, see GUESSING THE
30 IMAGE GEOMETRY below).
31 -b number
33 number of bands in input image (1 by default).
34 -d data_type
36 type of samples in input image, where data_type may be:
37 byte 8-bit unsigned integer (default),
38 short 16-bit unsigned integer,
39 long 32-bit unsigned integer,
40 sbyte 8-bit signed integer,
41 sshort 16-bit signed integer,
42 slong 32-bit signed integer,
43 float 32-bit IEEE floating point,
44 double 64-bit IEEE floating point.
45 -i config
47 type of samples interleaving in input image, where config may
48 be:
49 pixel pixel interleaved data (default),
50 band band interleaved data.
51 -p photo
53 photometric interpretation (color space) of the input image,
54 where photo may be:
55 miniswhite white color represented with 0 value,
56 minisblack black color represented with 0 value (default),
57 rgb image has RGB color model,
58 cmyk image has CMYK (separated) color model,
59 ycbcr image has YCbCr color model,
60 cielab image has CIE L*a*b color model,
61 icclab image has ICC L*a*b color model,
62 itulab image has ITU L*a*b color model.
63 -s swap bytes fetched from the input file.
65 -L input data has LSB2MSB bit order (default).
67 -M input data has MSB2LSB bit order.
69 -c Specify a compression scheme to use when writing image data: -c
71 none for no compression, -c packbits for the PackBits compres‐
72 sion algorithm (the default), -c jpeg for the baseline JPEG com‐
73 pression algorithm, -c zip for the Deflate compression algo‐
74 rithm, and -c lzw for Lempel-Ziv & Welch.
75 -r number
77 Write data with a specified number of rows per strip; by default
78 the number of rows/strip is selected so that each strip is
79 approximately 8 kilobytes.
80
82 raw2tiff can guess image width and height in case one or both of these
83 parameters are not specified. If you omit one of those parameters, the
84 complementary one will be calculated based on the file size (taking
85 into account header size, number of bands and data type). If you omit
86 both parameters, the statistical approach will be used. Utility will
87 compute correlation coefficient between two lines at the image center
88 using several appropriate line sizes and the highest absolute value of
89 the coefficient will indicate the right line size. That is why you
90 should be cautious with the very large images, because guessing process
91 may take a while (depending on your system performance). Of course, the
92 utility can't guess the header size, number of bands and data type, so
93 it should be specified manually. If you don't know anything about your
94 image, just try with the several combinations of those options.
95 There is no magic, it is just a mathematical statistics, so it can be
97 wrong in some cases. But for most ordinary images guessing method will
98 work fine.
