NAME

       VistaIOSelectBand - select bands of image pixels

SYNOPSIS

       #include <vistaio.h>

       VistaIOBoolean VistaIOSelectBand (routine, image, band, npixels, first_pixel)
              VistaIOStringConst routine;
              VistaIOImage image;
              VistaIOBand band;
              int *npixels;
              VistaIOPointer *first_pixel;

ARGUMENTS

       routine   Names  the routine that is using VistaIOSelectBand to check its arguments.  This
                 name is included in any error messages produced by VistaIOSelectBand.

       image     Specifies the image whose pixels are to be selected.

       band      May specify  a  particular  band  of  the  image  to  be  selected,  or  may  be
                 VistaIOAllBands to indicate that all bands of the image should be selected.

       npixels   Returns the number of pixels selected, or may be NULL

       first_pixel
                 Returns the address of the first pixel selected, or may be NULL

DESCRIPTION

       VistaIOSelectBand selects one or all bands of an image for processing.

       The  image  argument  specifies  the image, and band specifies either a single band or all
       bands of that image. VistaIOSelectBand checks the validity of those  two  arguments,  then
       returns  via  npixels and first_pixel the number and location of the selected pixels. (The
       pixels will be occupying a contiguous block of memory.) Either npixels or first_pixel  may
       be NULL if the corresponding return value is wanted.

RETURN VALUES

       VistaIOSelectBand  returns  TRUE if its image and band arguments are consistent, and FALSE
       otherwise.

SEE ALSO

       VistaIOImage(3),

DIAGNOSTICS

       ``Routine: Band band referenced in image of nbands band(s).''
              The band argument is invalid given the number of bands in image.  Routine  will  be
              the name supplied by the routine argument.
