4.3 Image Output Parameters

4.3.1 Generic Image Output

create_image boolean
If true, an image is created and output.
image_file filename
The image is output to this file. If it is ‘stdout’, the image is written to the standard output stream, if it is ‘stderr’, it is written to the standard error stream.
image_fmt enumerated string
The image may be written in any of the formats indicated in Images. This parameter selects which format to use. The available choices are: ‘ascii-raw’, ‘ascii-hdr’, ‘binary-raw’, ‘binary-hdr’, ‘rdb-raw’, ‘rdb-hdr’;
image_lang enumerated string (‘c’ | ‘fortran’)
The binary formats of an image may be written in either C or Fortran compatible records. This parameter selects which is used.

4.3.2 ascii Image Output

ascii images are printed in i major form; i.e., bins with a single value of i are printed most rapidly.

i_prefix string
This string precedes the printing of a sequence of bins with the same i value. It is often left blank.
i_prefix string
This string is printed after a sequence of bins with the same i value is printed, and before the printing of bins with the succeeding i. It is usually the string ‘\n’, indicating that a new line is to begin.
wt_format string
This is a printf style format string used to print the weight of a bin. It should not contain any padding to separate bin values.
j_pad string
This parameter specifies what will be printed between bin values. It's usually ‘\t’.

4.3.3 ‘/rdb’ Image Output

/rdb’ images are printed in i major form; i.e., bins with a single value of i are printed most rapidly.

wt_format string
This is a printf style format string used to print the weight of a bin. It should not contain any extra padding.
pos_format string
This is a printf style format string used to print the position of a bin. It is used once for each coordinate. It should not contain any padding to separate bin values.
