ARC, Inc - API Documentation

Integer class constants that correspond to indexes for the naxes values returned by a call to the GetParameters method. One constant corresponds to the valid size of the naxes array.

NAME	DESCRIPTION	VALUE
NAXES_COL	Naxes array index for image column dimension ( in pixels )	0
NAXES_ROW	Naxes array index for image row dimension ( in pixels )	1
NAXES_NOF	Naxes array index for number of frames in FITS file	2
NAXES_SIZE	Required size of naxes array when passed into GetParameters method.	3

        // This code demonstrates how to read the image
        // dimensions from the naxes header values.
