The EFONT procedure provides a simple widget-based vector font editor and display. Use this procedure to read and/or modify a local copy of the file
hersh1.chr, located in the
resource/fonts subdirectory of the main IDL directory, which contains the vector fonts used by IDL in plotting. This is a very rudimentary editor. Click the "Help" button on the EFONT main menu for more information.
This routine is written in the IDL language. Its source code can be found in the file
efont.pro in the
lib subdirectory of the IDL distribution.
EFONT [, Init_Font] [, /BLOCK] [, GROUP=widget_id]
The initial font index, from 3 to 29. The default is 3.
Set this keyword to have XMANAGER block when this application is registered. By default, BLOCK is set equal to zero, providing access to the command line if active command line processing is available. Note that setting BLOCK=1 will cause all widget applications to block, not just this application. For more information, see the documentation for the NO_BLOCK keyword to XMANAGER.
The widget ID of the widget that calls EFONT. If GROUP is set, the death of the caller results in the death of EFONT.
