Spectral displays, and various plots, can be exported into a wide variety of graphical file formats. Vector formats are useful if you want to preserve the full resolution of the spectral display. Bitmaps are exported at the resolution the spectrum is currently displayed at and are useful for posting on web sites, for example.
Premium Canvas Support
One of the new premium features included if you are a paying support customer is the ability to create rich annotated displays directly in NMRViewJ. Spectra are displayed on a canvas and can be arranged in any way much like graphical objects in illustration programs. You're not limited to the normal grid display of the standard NMRViewJ window so you can have overlays and inset spectra. And you can add a wide variety of graphical objects, including annotation pointers, lines, rectangles, arcs, and formatted text with multiple fonts, superscripts, subscripts and any Unicode character. Charts are just one more graphical item so you can even add them. This illustration was done with a simple script that, on the fly, generated a plot from the intensities of a selected set of peaks.
