# uves\_utl\_ima\_arith(7)

Computes result of ima1 op ima2

## NAME

uves\_utl\_ima\_arith - Computes result of ima1 op ima2

## SYNOPSIS

esorex **uves\_utl\_ima\_arith** \[OPTIONS\] FILE.sof

## DESCRIPTION

This recipe performs image computation.

The input files are 2 images their associated tags should be RAW\_IMA.

The output is an image resulting from the RAW\_IMA op RAW\_IMA where op indicates the operation to be performed specified by the parameter  uves.uves\_utl\_ima\_arith.op having alias ´op´ Information on relevant parameters can be found with esorex --params uves\_utl\_ima\_arith esorex --help uves\_utl\_ima\_arith

## OPTIONS

- **--op** *\<str\>*

  A possible operation (str; default: ´+´). The full name of this option for the EsoRex configuration file is **uves.uves\_utl\_ima\_arith.op** \[default = *+*\].

- **--value** *\<float\>*

  a value (float; default: 9999.0). The full name of this option for the EsoRex configuration file is **uves.uves\_utl\_ima\_arith.value** \[default = *9999.0*\].

Note that it is possible to create a configuration file containing these options, along with suitable default values. Please refer to the details provided by the 'esorex --help' command.
