# mia-3dimagecombine(1)

Combine two 3D images.

## NAME

mia-3dimagecombine - Combine two 3D images.

## SYNOPSIS

**mia-3dimagecombine -1 \<image1\> -2 \<image2\> -c \<combiner\> -o \<out-file\> \[options\]**

## DESCRIPTION

**mia-3dimagecombine** This program is used to combine two images using a given image combiner.

## OPTIONS

- \-1 --image1=(input, required); io

  input image  1 to be combined\
    For supported file types see PLUGINS:3dimage/io

- \-2 --image2=(input, required); io

  input image  2 to be combined\
    For supported file types see PLUGINS:3dimage/io

- \-c --combiner=(required); factory

  combiner operation\
    For supported plugins see PLUGINS:3dimage/combiner

- \-o --out-file=(output, required); io

  output image file\
    For supported file types see PLUGINS:3dimage/io

### Help & Info

- \-V --verbose=warning

  verbosity of output, print messages of given level and higher priorities. Supported priorities starting at lowest level are:

  *trace* ‐ Function call trace

  *debug* ‐ Debug output

  *info* ‐ Low level messages

  *message* ‐ Normal messages

  *warning* ‐ Warnings

  *fail* ‐ Report test failures

  *error* ‐ Report errors

  *fatal* ‐ Report only fatal errors
