Description

imagesize = getImgSize(fptr) returns the number of rows and columns of an image. This function corresponds to the fits_get_img_size (ffgisz) function in the CFITSIO library C API.

Examples

import matlab.io.*;
fptr = fits.openFile('tst0012.fits');
hdus = [1 3 4];
for j = hdus;
    htype = fits.movAbsHDU(fptr,j);
    sz = fits.getImgSize(fptr);
    fprintf('HDU %d:  "%s", [', j, htype);
    for k = 1:numel(sz)
        fprintf(' %d ', sz(k));
    end
    fprintf(']\n');
end
fits.closeFile(fptr);
