LYNX Version 4.8: October 1998

New Data Structure Functionality

Variable Values Stored with Volume Components

The volume data structure now allows storage of estimated variable values and associated standard error values with each component. This enhancement is required for the new Direct Volume Estimation application.

New Interface Functionality

Save Parameters Functionality

All major applications now have a Save Parameters pushbutton to allow you to save the current form's parameters. These parameters are automatically loaded the next time the form is opened.

Background Process Functionality

All major applications are now run as a background process - freeing-up the main interface so that you can continue with other work. Any form that has the Save Parameters pushbutton will run as a background process when you click OK. Any application that is executed as a background process can also be run as a Batch Process so you can schedule several applications to run at once.

New Interactive Graphics Functionality

Viewplane Pan Function

The generic graphics function menu now includes a viewplane pan function for interactive XY shift of the viewplane.

Escape Available for Viewplane Functions

Escape can now be used with the graphics functions Zoom Fix, Zoom Free, Pan, X-Section, Y-Section, T-Section and Vector. Escape can be used to exit the function at any time.
