matlab.io.fits.setCompressionType
Set image compression type
Syntax
setCompressionType(fptr,comptype)
Description
setCompressionType(fptr,comptype)
specifies
the image compression algorithm that should be used when writing a
FITS image.
Supported values for comptype
include:
'GZIP' |
'GZIP2' |
'RICE' |
'PLIO' |
'HCOMPRESS' |
'NOCOMPRESS' |
This function corresponds to the fits_set_compression_type
function
in the CFITSIO library C API.
Examples
import matlab.io.* fptr = fits.createFile('myfile.fits'); fits.setCompressionType(fptr,'GZIP2'); fits.createImg(fptr,'long_img',[256 512]); data = reshape(1:256*512,[256 512]); data = int32(data); fits.writeImg(fptr,data); fits.closeFile(fptr); fitsdisp('myfile.fits','mode','full');
