Introduction
------------
     
     GENUS is a fast and powerful editor for Calamus typefaces that uses
     an icon-based user interface designed for "at-a-glance" operation.
     Once you get accustomed to the icons, switching functions and
     invoking features becomes very quick and easy. 

     To make it even simpler to learn to use GENUS's tools, there is an
     automatic help feature that shows you the function of each icon
     (in the title bar at upper right) as you pass the mouse cursor
     over it. 

     The drawing screen incorporates a ruler at the top and side with 
     guide marks displayed and changeable at any time simply by 
     clicking, holding and dragging the letters on the ruler.

     The guide lines are marked on the top ruler as "L" (left em
     square), "C" (center), and "R" (right em square).  The side ruler
     marks "U, A, X, B, D, L" are Upper em square, Ascender, X-height,
     Baseline, Descender and Lower em square.

     Although the side guide lines are freely positionable, they
     should remain in this order.  The top guide lines are also 
     adjustable, but the "C" line always remains in the center.
     Guidelines can be locked by clicking the black box where the top
     and side rulers meet.  An "L" will be displayed when the rulers
     are locked.

     Calamus uses the position information of these guide lines to
     properly display the characters.  The most important settings
     are the base line and the upper and lower em square.
     

The Icons
---------

     Arrow icon:  Selected by default.  Use to select and move points.
     
   Clipper icon:  Select this icon to delete lines and curves.
                  Disable this function by right-clicking  or choosing
                  another icon.

    Pencil icon:  This along with a LINE or CURVE icon will allow you 
                  to draw lines or curves.  Place starting points by
                  left-clicking with ONLY the pencil icon highlighted.
                  Choose the curve or line icon to continue.
                  
     Line/curve:  These icons, when selected, determine whether lines or
                  curves will be placed.
                    
                  Note: You may toggle between lines and curves while
                  drawing by using the right mouse button.

    Auto smooth:  When highlighted a small cross cursor is displayed.
                  Click on any point of a path containing curves
                  that you wish smoothed.  Four curves set in a diamond
                  or square will generate a circle.  Right click to exit
                  this mode.

   Reverse icon:  Reverses the drawing direction of a path.  When 
                  selected, the mouse changes to a small cross hair.
                  It will de-select itself after you click on any point
                  in a path.  Disable by a right-click.  The direction
                  of a path can be shown in the kerning window.
     
    Connect end   This will cause all open paths to connect into 
         points:  closed paths. A CLOSE PATH Routine is also called
                  when changing characters or invoking the disk 
                  icon.

      Snap icon:  For invoking the snap-to-grid function.  Snap 
                  coordinates can be set from the calculator.

     Select all:  Click this icon to select all points of all paths.
     (lasso)
          
      Disk icon:  The disk icon will display a dialog box where you
                  may load, save, merge or erase font files on your
                  disk.  This is also where you fill in the details of
                  font name, your name, company etc.
       
      Bit-Image:  A fat-bit editor for the font label.

      Clipboard:  For temporary storage of paths or characters.

                  NOTE: Full clipboards may be cleared by pressing the
                  F1 or F2 keys.
     
     Calculator:  Allows mathematical modifications to sub paths, 
                  full characters, or globally to all characters.

       Pin icon:  This icon lets you define the center of rotation.

        Kerning:  For defining the kerning bars for optimized or 
                  character width kerning.
                  
       Tangents:  Turns the display of curve tangent lines on and off.

      Free_form   Selecting this icon allows you to draw free-form
      helplines:  helplines that will appear on the screen in the
                  same position no matter which character you are
                  editing.
                  The lines are drawn by left-clicking the start
                  point on the draw screen and, while holding the
                  mouse key down, drawing the line out in
                  any direction.  You may have up to 10 lines and 
                  10 circle/ellipses.
                  To erase helplines, right-click the start point.
                  Exit this function by right-clicking.
     
      Free-form   Ellipse lines are placed in an identical manner
       Ellipses:  as helplines.
 
                  Helplines are toggled on and off with the F9 key.

      Zooms:      There are four levels of magnification.  While in a
                  zoom level from 2 to 4 you may pan and scroll using
                  the black bars that are superimposed over the rulers.

      Link icon:  This will link all previously separate paths into 
                  one continuous path. Paths are linked in the order
                  they were placed on the draw screen with the end
                  point of the first path being connected to the start
                  of the next path and so on.

     Copy Image:  While working on a font, you may wish to copy the
                  the image of a character to the background to 
                  act as  guide when working on a similar shaped
                  character. i.e. "e,c" or "p,b".
 
         Camera:  Choosing this icon will allow you to load a scanned
                  image saved in Degas PI3,PC3 or IMG format.

                  NOTE: The background images are toggled on and off 
                  with the F10 key.
     
   Screen Saver:  Invoke the built in screen saver with this icon.
                  When this icon is selected, GENUS automatically blanks
                  the screen after 4 minutes of inactivity to save your
                  screen from "burn-in."  A small analog clock is
                  displayed in random positions during this time.
                  Hit any key or mouse button to re-activate the editor.
     
     Trash icon:  For deleting full characters or paths. If no path is 
                  selected the full character is deleted. If you
                  hit the trash by mistake you may recover the
                  character by using the UNDO key.
          
           Desk:  Will clear the screen and display a standard GEM menu
                  bar. You may now call any accessories that you have 
                  installed. Choosing "Return To Editor" from the 
                  header on the accessory drop down menu will
                  re-display the editor where you left off.


     All the definable characters are displayed in the character table.
     To choose a character for editing, simply click it.
     If you click on the black bar at the top of the character table 
     ALL the defined characters are shown as inverse.  Clicking again, 
     anywhere on the screen, returns the table to normal.
     
     An alternative character table is available by clicking the 
     table "switch" at the upper right of the table. This will 
     display the 28 character shapes and their corresponding keyboard 
     character. A scroll bar is incorporated to move to any character.
          
     Underneath the character table you may display any of two fonts 
     that you may load in from the File menu. You may transfer full
     characters or paths through the buffers back and forth between 
     fonts.  Click the font that you want active at any time.


Accessing files:
----------------

     When you choose the disk icon, a dialog box will appear 
     that will allow access to your files on floppy or hard disk 
     systems. This dialog box is also where you fill in 
     information on the font name, creator and company. To enter 
     or change information in this area, just click anywhere on the
     line you wish to edit. Pressing the ESC key will clear the 
     line of any information it holds and allow you to type in the 
     information you wish to be saved along with the font itself.
     
     Accessing the files is accomplished by moving the mouse into 
     the box marked DISK. A drop down menu will appear where you 
     may:

          LOAD CALAMUS     Load an existing Calamus font file.
     
          SAVE CALAMUS     Save the current file in memory.
                           (NOTE: This feature is disabled in the
                           demo version.)

         MERGE CALAMUS     Merge an existing Calamus format font file;
                           any undefined character cells in the font
                           currently in memory are filled with any
                           characters that exist in those cells.
     
            LOAD OTHER     Load an existing PageStream or Publishing
                           Partner font for conversion to a Calamus
                           font.

              SAVE CVG     Save any single character cell as a Calamus
                           Vector Graphic file.
                           (NOTE: This feature is disabled in the
                           demo version.)
      
              LOAD CVG     Load a simple (monochrome) CVG image.
     
      SAVE PREFERENCES     Saves all the settings of the calculator,
                           the current paths and the last picture file
                           type that you have accessed. The next time
                           you boot Genus, the settings will be
                           remembered.
                           NOTE: Paths are set by loading the different
                           file types from their current locations.
          
                  QUIT     Quit Genus and exit to the desktop.


Selecting Points
----------------

     (With the arrow icon highlighted)

     To select all points on a single path, hold down the Alternate key
     and click any point in that path.

     To select individual points without deselecting previously select
     points, hold the Shift key while left-clicking a point.  To
     deselect a point, simply click it again.  Missing a point (too far
     away for the routine to find the point) will NOT cause all the
     points to be deselected, as long as you are holding the SHIFT or
     ALT key.

     GROUP SELECTION: While holding the LEFT-SHIFT key, click somewhere to
     the upper left of a group of points that you wish to select.
     The editor will first search the character data for a point within
     range (3 pixel area around a point).  If no point is found, the 
     editor will show the mouse as an arrow.  Now when you move the
     mouse to the lower right a rubber box will be drawn allowing you
     to surround a group of points within this box.
     On releasing the mouse button all points within the box will be 
     selected.  This is especially useful when you want to select a 
     group of points that overlap on top of each other allowing you to
     move them all at once ... for instance, a start and end point that 
     are in the same position. 

     Note: If you try to copy any points selected in this way into the 
     clip-boards, they will not copy.  Individual points cannot
     be stored this way.  Only full paths selected with ALT-click or 
     full characters may be placed into the clip-boards.  Box selection
     of points (even all points) defines them as individual points and 
     not full paths. 
     
     Each point remains selected until you left-click somewhere off
     the character without holding the SHIFT or ALT key.  All selected
     points will then be deselected.
