 	 box x0,y0,z0 x1,y1,z1 value

## DESCRIPTION

Generate 3D digital phantom images using a selection of drawing commands

## OPTIONS

### Global Toolkit Options (these are shared by all CMTK tools)

- **--help**

  Write list of basic command line options to standard output.

- **--help-all**

  Write complete list of basic and advanced command line options to standard output.

- **--wiki**

- **--man**

  Write man page source in 'nroff' markup to standard output.

- **--version**

  Write toolkit version to standard output.

- **--echo**

  Write the current command line to standard output.

- **--verbose-level** *\<integer\>*

  Set verbosity level.

- **--verbose**, **-v**

  Increment verbosity level by 1 (deprecated; supported for backward compatibility).

- **--threads** *\<integer\>*

  Set maximum number of parallel threads (for POSIX threads and OpenMP).

### Main Options

- **--dims** *\<string\>*, **-D** *\<string\>*

  Set dimensions in voxels

- **--voxel** *\<string\>*, **-V** *\<string\>*

  Set voxel size in \[mm\]

- **--coordinates**

  Coordinate specification mode. Supported values: "indexed", "absolute", "relative", where the default is "indexed", or use one of the following:

  - **--indexed**

    Use grid indexes to specify coordinates. For each dimension, the valid value range is \[0,Dims-1\]. **\[This is the default\]**

  - **--absolute**

    Use absolute volume coordinates. For each dimension, the valid range is \[0,FOV\].

  - **--relative**

    Use relative volume coordinates. For each dimension, the valid range is \[0,1\].

- **--char**, **-c**

  8 bits, signed

- **--byte**, **-b**

  8 bits, unsigned

- **--short**, **-s**

  16 bits, signed

- **--ushort**, **-u**

  16 bits, unsigned **\[This is the default\]**

- **--int**, **-i**

  32 bits signed

- **--float**, **-f**

  32 bits floating point

- **--double**, **-d**

  64 bits floating point

- **--bg** *\<double\>*, **-B** *\<double\>*

  Set the image background value (use to initialize newly created image). **\[Default: 0\]**

- **--import** *\<string\>*, **-I** *\<string\>*

  Import image **\[Default: NONE\]**

- **--import-grid** *\<string\>*

  Import image grid only, ignore data **\[Default: disabled\]**
