Re-size a fits image
Usage
mShrink [-f]
[-d
level]
[-h
hdu]
[-s
statusfile]
in.fits
out.fits
factor
Overview
A utility for reducing the size of a FITS file, by averaging blocks of pixels.
Options
-
-f -
Fixed-size flag - specify output size of image, instead of the size of blocks of pixels to be averaged
-
-d level -
Turns on debugging to the specified level (1-4).
-
-s statusfile -
Output and errors are sent to statusfile instead of to stdout
Arguments
- in.fits
-
Input FITS file
- out.fits
-
Path to output FITS file.
- -h hdu
-
Use the specified FITS extension (default is to use the first HDU with image data)
- factor
-
Size of blocks, in pixels, to average. File size will be reduced by 1/factor squared. If the -f (fixed-size) flag is used, factor is the desired width of the output image.
Result
[Normal mode]: FITS output image, reduced in size by a factor of (1/factor)^2 .
[Fixed-size mode]: FITS output image of width factor
