NAME
      sunalign - takes a sun rasterfile and word aligns its scanlines

SYNOPSIS
      sunalign sunrasterfile

DESCRIPTION

Sunalign takes the file sunrasterfile and determines if the stored scan lines in the file require word alignment. If so, the command overwrites the image data making scan lines word aligned. This command is useful when taking clipped images from the HP Scan Jet and importing them into Frame Maker.

OPTIONS
      sunrasterfile
            any sun rasterfile image

EXAMPLES
       sunalign foo.ras

FlLES
      / usrl include/ rasterfile.h
            sun's raster header include file

SEE ALSO
      rasterfile(5)

DIAGNOSTICS
      Sunalign exits with a status of -1 if opening sunrasterfile fails.

GRP4DECOMP(3)                                             C LIBRARY FUNCTIONS                              GRP4DECOMP(3)

NAME

grp4decomp - takes an CCITT Group 4 Compressed input buffer and returns an output buffer of uncompressed data

SYNOPSIS

           grp4decomp(indata, inbytes, width, height, outdata, outbytes)
           unsigned char *indata, *outdata;
           int inbytes, width, height, *outbytes;

DESCRIPTION

grp4decomp() takes the input buffer indata of length inbytes and decompresses it returning the uncompressed data in the output buffer outdata with length outbytes. This procedure was developed by the CALS Test Network and adapted for use by NIST. The source is found under src in the file g4decomp.c.

indata - the compressed data input buffer

inbytes - the length of the input data in bytes

width - the pixel width of the image from which the input data came

height - the pixel height of the image from which the input data came

outdata - the output beffer in which the uncompressed data is to be returned

outbytes - a pointer to the length in bytes of the uncompressed output data

SEE ALSO
           readihdrfile(3)

BUGS
           NOTE: Grp4decomp will only work with binary image data.

READIHDRFILE (3)                                C LIBRARY FUNCTIONS                              READIHDRFILE (3)

NAME
      readihdrfile - loads into memory an IHead structure and corresponding binary image data from a file

SYNOPSIS
      #include <ihead.h>
      readihdrfile(file, head, data, width, height)
      char *file;
      IHead **head;
      unsigned char **data;
      int *width, *height;

DESCRIPTION

readihdrfile0 opens a file name file and allocates and loads into memory an IHead structure and its corresponding binary image data. If the image data is compressed, readihdrfile win uncompress the data before returning the data buffer. This routine also returns several integers convened from their corresponding ASCII entries found in the header. The source is found under src in the file loadhsf.c.

file       - the name of the file to be read from

head    - a pointer to where an IHead structure is to be allocated and loaded

data     - a pointer to where the array of binary raster image data is to be allocated and loaded

width       - integer pointer containing the image's pixel width upon return

height     - integer pointer containing the image's pixel height upon return

SEE ALSO
      g4decomp(3)

DIAGNOSTICS
      readihdrfile() exits with -1 when opening file fails or the image contains multiple bit planes.
