+ raw2tiff − create a TIFF file from a +raw data + |
+
| + |
+ raw2tiff [ options ] input.raw +output.tif + |
+
| + |
+ 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. + |
+
| + |
+ −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). + |
+
| + |
+ −l <number> |
+
| + |
+ length of input image in lines(can be guessed, see +GUESSING THE IMAGE GEOMETRY +below). + |
+
| + |
+ −b <number> |
+
| + |
+ number of bands in input image (1 by default). + |
+
| + |
+ −d data_type |
+
| + |
+ type of samples in input image, where data_type +may be: |
+
| + |
+
+ 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, + |
++ | +
| + |
+
+ slong + |
++ |
+
+ 32-bit signed integer, + |
++ | +
| + |
+
+ float + |
++ |
+
+ 32-bit IEEE floating point, + |
++ | +
| + |
+
+ double + |
++ |
+
+ 64-bit IEEE floating point, + |
++ | +
| + |
+ −i config |
+
| + |
+ type of samples interleaving in input image, where +config may be: |
+
| + |
+
+ pixel + |
++ |
+
+ pixel interleaved data (default), + |
++ | +
| + |
+
+ band + |
++ | +
+
+ band interleaved data. + |
++ | +
| + |
+ −p photo |
+
| + |
+ photometric interpretation (color space) of the input
+image, where photo may be: |
+
| + |
+
+ 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, and −c lzw for Lempel-Ziv & +Welch. + |
++ | +
| + |
+ −r <number> |
+
| + |
+ Write data with a specified number of rows per strip; by +default the number of rows/strip is selected so that each +strip is approximately 8 kilobytes. + |
+
| + |
+ raw2tiff 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. + |
