Montage Viewer: Other Montage Modules
Of course, all of the other Montage modules can be of use when creating the image files that are
then sent to mViewer but there are a few that are particulary usefule with regard to presentation:
mViewer will alway produce a PNG/JPEG of the whole image it is
given. To cut out a piece for display, use these tools. This was done for most of the
examples on these pages; the original SDSS mosaics used were twice as big in both dimensions.
Similarly, mViewer transform one pixel in the FITS files to one
display pixel. To changes the scale, use these tools. mShrink can shrink (or expand) the
scale by non-integer factors. Alternatively, you can shrink/expand to a target size.
This tool will return overall statistics on an image (e.g., the
pixel scale, center coordinates, and so on. This is useful in deciding how to run the
above tools and particularly useful in the Python/Web applications based on mViewer.
