UNIPEN Tcl/Tk Screen Dumps

If you have installed the latest Tcl/Tk versions, you can also use our Tcl/Tk-based UNIPEN interface software. The software uses a shared library version of the three libraries uplib, upsiglib and uphierarchy. For each level in a UNIPEN file, a menu can be popped up which lists all entries and allows selecting a SEGMENT:

When selecting an item, a 'video player' is started which depicts the selected segment:

Using the middle button, a popup menu comes up, via which 'actions' can be performed on the selected segment, such as 'resample'. The result of a spatially resampled segment is depicted in a window below the raw input signal:

An action for segments is to show their 'children' or 'parents'. These keywords are defined in the uphierarchy library. For example a UNIPEN segment 'CHAR' has a parent in the 'WORD' hierarchy. The next image shows a character and its position in the parent:

How do they do it?

   #!/usr/local/bin/wish
   load /usr/local/lib/unipen/tcl_uplib.so uplib   # This is the actual trick!
                                             # Here Uplib routines are made
                                             # accessible to your Tcl/Tk script
     .
     .

   set hierlist [uplib_get_hierarchies "my-unipen-file.dat"]
                                             # Note: this is a call to 
                                             # a C routine!
   puts stdout "$hierlist"
     .
     .
     .
