You might want to study the example draw_widget_data.pro in the
examples/doc/widgets subdirectory of the IDL distribution.

It does what you want... basically you read the X;Y coordinates of the
cursor, transform that to row;colum coordinates, then read the data
underneath. You can easily add this data to an existing variable, and
when you are done, simply save your variable or print it in a file,
using the method in Conor's message.
