Stitch a panorama image

## NAME

nona - Stitch a panorama image

## SYNOPSIS

**nona** \[options\] **-o** *output* *project\_file* (image files)

## DESCRIPTION

**nona** uses the transform function from PanoTools, the stitching itself is quite simple, no seam feathering is done.

Only the non-antialiasing interpolators of PanoTools are supported.

The following output formats (**n** option of PanoTools **p** script line) are supported:

- JPEG, TIFF, PNG : Single image formats without feathered blending

  - JPEG\_m, TIFF\_m, PNG\_m : multiple tiff files

  - TIFF\_multilayer : Multilayer tiff files, readable by The Gimp 2.0

  ## OPTIONS

General options:

- **-c**

  Create coordinate images (only TIFF\_m output)

- **-v**

  Quiet, do not output progress indicators

- **-d**

  print detailed output for GPU processing

- **-g**

  perform image remapping on the GPU

The following options can be used to override settings in the project file:

- **-i** *num*

  Remap only image with number num (can be specified multiple times)

- **-m** *str*

  Set output file format (TIFF, TIFF\_m, TIFF\_multilayer, EXR, EXR\_m, JPEG, JPEG\_m, PNG, PNG\_m)

- **-r** *ldr*/*hdr*

  Set output mode:

  - ldr - keep original bit depth and response

    - hdr - merge to hdr

    - **-e** *exposure*

  Set exposure for ldr mode

- **-p** *TYPE*

  Pixel type of the output. Can be one of:

  - UINT8 8 bit unsigned integer

    - UINT16 16 bit unsigned integer

    - INT16 16 bit signed integer

    - UINT32 32 bit unsigned integer

    - INT32 32 bit signed integer

    - FLOAT 32 bit floating point

    - **-z\|--compression**

  Set compression type. Possible options for tiff output:

  - NONE no compression

    - PACKBITS packbits compression

    - LZW LZW compression

    - DEFLATE deflate compression

    For JPEG output set quality number

- **--ignore-exposure**

  Don't correct exposure. (This doesn't work with the -e switch)

- **--save-intermediate-images**

  Saves also the intermediate images (only when output is is TIFF, PNG or JPEG)

- **--intermediate-suffix=SUFFIX**

  Suffix for intermediate images

- **--create-exposure-layers**

  Create all exposure layers (this will always use TIFF)

- **--clip-exposure\[=lower cutoff:upper cutoff\]**

  Mask automatically all dark and bright pixels. Optionally you can specify the limits for the lower and upper cutoff (specify in range 0...1, relative the full range)
