Compress HDU from one file into another
imgCompress(infptr,outfptr)
imgCompress(infptr,outfptr) initializes
the output HDU, copies all the keywords, and loops through the input
image, compressing the data and writing the compressed data to the
output HDU.
This function corresponds to the fits_img_compress function
in the CFITSIO library C API.
import matlab.io.* infptr = fits.openFile('tst0012.fits'); outfptr = fits.createFile('myfile.fits'); fits.setCompressionType(outfptr,'rice'); fits.imgCompress(infptr,outfptr); fits.closeFile(infptr); fits.closeFile(outfptr);
