Set scale parameter for HCOMPRESS algorithm
setHCompScale(fptr,scale)
setHCompScale(fptr,scale) sets the scale
parameter to be used with the HCOMPRESS compression algorithm. Setting
the scale parameter causes the algorithm to operate in lossy mode.
This function corresponds to the fits_set_hcomp_scale function
in the CFITSIO library C API.
import matlab.io.* data = 50*ones(256,512,'double') + 10 * rand([256 512]); fptr = fits.createFile('myfile.fits'); fits.setCompressionType(fptr,'HCOMPRESS_1'); fits.setHCompScale(fptr,2.5); fits.createImg(fptr,'double_img',[256 512]); fits.writeImg(fptr,data); fits.closeFile(fptr); fitsdisp('myfile.fits','mode','full');
