Tag | Description |
---|---|
-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:
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, 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. |
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.
