NAME


mViewer - Render multi-dimensional images and large-scale images

DESCRIPTION


mViewer generates a JPEG image file from a FITS file (or a set of three
FITS files in full color). A data range for each image can be defined,
and the data can be stretched by any power of the log() function
(including zero: linear) or using custom gaussian histogram equalization
algorithms. Pseudo-color color tables can be applied
in single-image mode.

mViewer can also generate overlays on the image of coordinate grids,
source catalogs (with scaled symbols), image outlings from metadata tables,
plus various markers and labels.

Along with a few other Montage modules, mViewer can be wrapped to support
interactive image analysis from Python or through AJAX web interfaces.

The functionality of mViewer goes beyond what is reasonable to capture
in a man page. The user is therefore directed to the
mViewer documentation suite.

Examples:

To create a grayscale image from a FITS file:

To create a full color image from three co-registered FITS files:

A complex example with a catalog overlay (symbol size, shape and color controled by table
columns), image metadata, a coordinate grid and some custom labeling:
