NAME

       pnmtov - convert portable anymap (PNM) image to Vista data file

SYNOPSIS

       pnmtov [-option ...] [infile] [outfile]

DESCRIPTION

       pnmtov converts an image from a portable anymap (PNM) file to a Vista data file. The following types of portable anymap may be converted:

	 o Portable  bitmap (PBM) and its ``rawbits'' variant. A PBM image is converted to a single-band Vista image with bit pixels. Pixel values
	   0 and 1 are swapped since, for PBM images, 0 denotes white and 1 denotes black.

	 o Portable graymap (PGM) and its ``rawbits'' variant. A PGM image is converted to a single-band Vista image with ubyte pixels.  The  full
	   range of PGM pixel values is mapped to [0,255] in the returned image.

	 o Portable pixmap (PPM) and its ``rawbits'' variant. A PPM image is converted to an RGB color image (nbands: 3, ncolors: 3, color_interp:
	   rgb) with ubyte pixels. The full range of PPM pixel values is mapped to [0,255] in the returned image.

       A wide range of filters are available for converting other image formats to PNM.

COMMAND LINE OPTIONS

       pnmtov accepts the following options:

       -help	      Prints a message describing options.

       -in infile     Specifies the input file, which is a PBM, PGM, or PPM file.

       -out outfile   Specifies the output file, which will be a Vista data file.

       -name name     Specifies the name to be given the converted image. Default: ``image''.

       Input and output files can be specified on the command line or allowed to default to the standard input and output streams.

NAME

       vcatbands - concatenate image bands into a single image

SYNOPSIS

       vcatbands [-option ...] [infile ...] [> outfile]

DESCRIPTION

       vcatbands  concatenates one or more images to produce a single, multi-band image. All images read from all input files are combined to pro-
       duce a single image, which is written to the output file.

       The input images must all have the same number of rows, number of columns, and pixel representation.

COMMAND LINE OPTIONS

       vcatbands accepts the following options:

       -help	      Print a message describing options.

       -in infile ... Specifies one or more Vista data files containing images.

       -out outfile   Specifies where to write the output as a Vista data file.

       -name name     Specifies the name to be given the created image. Default: ``image''.

       -frame_interp none
       -viewpoint_interp none | stereo_pair
       -color_interp none | rgb
       -component_interp none | complex | gradient | intensity | orientation
		      Specify values for band interpretation attributes given to the new image.  All default to none.

       -nframes nframes
       -nviewpoints nviewpoints
       -ncolors ncolors
       -ncomponents ncomponents
		      Specify the number of frames, viewpoints, colors, and components represented by bands of the new	image.	If  not  specified
		      nframes  is  deduced  from  the number of bands in the image; the others have defaults based on what the various -..._interp
		      options have specified.

       Input files can be specified on the command line or allowed to default to the standard input stream. The output file can  be  specified	by
       the -out option or allowed to default to the standard output stream.

NOTES

       All input files are read before the output file is opened and written.
