matlab.io.fits.setHCompSmooth
Set smoothing for images compressed with HCOMPRESS
Syntax
setHCompSmooth(fptr,smooth)
Description
setHCompSmooth(fptr,smooth)
sets the smoothing
to be used when compressing an image with the HCOMPRESS algorithm.
Setting either the scale or smoothing parameter causes the algorithm
to operate in lossy mode.
This function corresponds to the fits_set_hcomp_smooth
function
in the CFITSIO library C API.
Examples
import matlab.io.* data = int32(50*ones(256,512,'double') + 10 * rand([256 512])); fptr = fits.createFile('myfile.fits'); fits.setCompressionType(fptr,'HCOMPRESS'); fits.setHCompSmooth(fptr,1); fits.createImg(fptr,'long_img',[256 512]); fits.writeImg(fptr,data); fits.closeFile(fptr); fitsdisp('myfile.fits','mode','full');
