nona — Stitch a panorama image


nona [options] -o output project_file (image files)


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


General options:

Create coordinate images (only TIFF_m output)
Quiet, do not output progress indicators
print detailed output for GPU processing
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

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


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
Don't correct exposure. (This doesn't work with the -e switch)
Saves also the intermediate images (only when output is is TIFF, PNG or JPEG)
Suffix for intermediate images
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)
