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
       TIFF_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

       -t num
	   Number of threads to be used (default: number of available cores)

       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)

       -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  Set compression type. Possible options for tiff output:

	   NONE      no compression
	   LZW	     LZW compression
	   DEFLATE   deflate compression

NAME

       ra_tiff - convert RADIANCE picture to/from a TIFF color or greyscale image

SYNOPSIS

       ra_tiff [ -z|-L|-l|-f|-w ][ -b ][ -e +/-stops ][ -g gamma ] { in.hdr|- } out.tif
       ra_tiff -r [ -x ][ -g gamma ][ -e +/-stops ] in.tif [ out.hdr|- ]

DESCRIPTION

       Ra_tiff converts between RADIANCE and TIFF image formats.  The -g option specifies the exponent used in gamma correction; the default value
       is 2.2, which is the recommended value for TIFF images.

       The -b option can be used to specify an 8-bit greyscale TIFF output file.  The type of input file is determined automatically.

       The -z option will result in LZW compression of the TIFF output file.  The -L option specifies SGILOG compression, which is recommended	to
       capture	the  full dynamic range of the Radiance picture.  However, since many TIFF readers do not yet support this format, use this option
       under advisement.  The -l option specifies SGILOG24 compressed output, which has less dynamic range than SGILOG, but may be smaller in some
       cases.	(It is usually larger.)  The -f option specifies 32-bit IEEE floating-point/primary output, which is the highest resolution format
       but results in very large files, since each RGB pixel takes 96 bits (12 bytes) and  does  not  compress	well.	The  -w  option  specifies
       16-bit/primary  output, which is understood by some photo editing software, such as Adobe Photoshop.  Decompression is automatically deter-
       mined for TIFF input.

       The -e option specifies an exposure compensation in f-stops (powers of two).  Only integer stops are allowed, for efficiency.

       The -r option invokes a reverse conversion, from a TIFF image to a RADIANCE picture.  The RADIANCE picture file can be taken from the stan-
       dard  input or sent to the standard output by using a hyphen ('-') in place of the file name, but the TIFF image must be to or from a file.
       The -x option can be used to specify an XYZE Radiance output file, rather than the default RGBE.

EXAMPLES

       To convert a Radiance picture to SGILOG-compressed TIFF format:

	 ra_tiff -L scene1.hdr scene1.tif

       To later convert this image back into Radiance and display using human visibility tone-mapping:

	 ra_tiff -r scene1.tif scene1.hdr
	 ximage -e human scene1.hdr

ACKNOWLEDGEMENT

       Work on this program was initiated and sponsored by the LESO group at EPFL in Switzerland.  Additions for the  SGILOG  data  encoding  were
       sponsored by Silicon Graphics, Inc.

BUGS

       Many TIFF file subtypes are not supported.
       A gamma value other than 2.2 is not properly recorded or understood if recorded in the TIFF file.
