> Arrow Keys

     Cursor  movement can be controlled by a number  of
     keys.   The arrow keys from the num pad will  move
     the  cursor in the direction desired.   Depressing
     the  key for a period of time will accelerate  the
     movement  of  the cursor in  that  direction.  The
     Arrow  Keys  have  been  designed  to  act  as  an
     alternative to Mouse interaction.
> File and Directory Access

     AdvanTex  comes with a complete file editor  which
     enables  you  to name files, change  these  names,
     import  files  from other directories  and  export
     files to other directories throughout your system.
     Refer  to  your  manual for  complete  details  on
     proper  file  creation  and  pathing   techniques.
     Basic DOS rules apply.

     When editing or naming a file or directory,  there
     are three keys to remember.  The home key on  your
     num pad will move the cursor line to the beginning
     of the file or directory name.  The left and right
     arrow  keys will allow you to skip over  the  name
     character  by character.  The back space key  will
     erase the next character to the left.
> Flip Image Functions

     This  creates  a  mirror  image  of  the  original
     graphics  file.  What first appeared on the  right
     hand  side of the image, is now on the  left  hand
     side.   The  Flip Vertical function  reverses  the
     pixel  columns  from top to  bottom,  creating  an
     upside down mirror image of the original  graphics
     file.
> General Help

     The help screens have been designed to give you  a
     few  basic operating instructions on  the  primary
     functions  and  capabilities  of  AdvanTex.    The
     screens can be used as a quick reference source to
     refresh  yourself on how to complete the  task  at
     hand.   These screens do not replace  the  manual,
     however.   Thorough explanations and  instructions
     of  all  capabilities of this  program  should  be
     sought in the user's manual.  The help screens are
     listed alphabetically starting with Arrow Keys and
     ending with Zoom Functions.
> Function Keys

     There  are function keys which correspond  to  the
     primary  functions  of  Advantex.  Any  of   these
     functions  may  be activated by  (1)  placing  the
     cursor over it and pressing Enter, 2) placing  the
     cursor  over  it and pressing the left  button  on
     your mouse, and 3) pressing the function key  (F1-
     F10) that corresponds to appropriate function.
> Invert Page

     The  Invert  Page feature allows you to  create  a
     negative of the image by changing all black pixels
     to  white  pixels, and all white pixels  to  black
     pixels.  The image will not be permanently altered
     unless  you  save the file, so feel free  to  play
     around with this feature.
> Keyboard

     AdvanTex   can  be  operated  by   the   keyboard.
     AdvanTex is a program that is easy to move  around
     in. The keypad keys change their meaning logically
     when in graphics mode.

> Mark Area, Cutout, and Erase

     AdvanTex  comes with the capability to draw a  box
     around  a specific area of the graphics  file  you
     wish  to edit.  There are no size  limitations  to
     how big or small the box must be.  To draw a  box,
     depress  the  F2  function key or  the  MARK  AREA
     selection under the EDIT Menu.  Initially you will
     have  the arrow cursor and a pair of  intersecting
     lines.  Place this intersection in any one of  the
     four  corners of the box you wish to draw.   Press
     enter  to anchor this corner of the box.  Now  use
     your  mouse or arrow keys to draw the rest of  the
     box.   Press  enter when you  are  satisifed  with
     where  the box is located.  You may now save  this
     boxed area as a new ATX, PCX, or TIF file.   After
     marking  off an area, you may choose to erase  the
     area  inside or outside of the box.  To erase  the
     area  within the box press F3 function  key.    To
     erase  the  area  outside of  the  box,  press  F4
     function  key.   Either function may  be  selected
     from your Edit menu.
> Straighten Page by Page Rotation

     If you wish to change the angle or orientation  of
     the  graphics  file  slightly,  you  can  use  the
     Straighten Page function.

     Select  "Straigten  Page". The  arrow  cross  hair
     cursor  appears with the intersecting lines.   The
     object  is for you to draw a reference  line  that
     AdvanTex  can  use as a guide for the  amount  you
     want to rotate the image.

     With the cross hairs at an initial position, press
     Enter.  This  temporarily anchors one end  of  the
     line  and  produces  a  little  square  drag  ICON
     (dragon).   Draw the line along some edge  in  the
     picture  that you want horizontal or  vertical  by
     moving the dragon to the right, left, up, or  down
     with  the  arrow keys. A rubber line  will  follow
     from  the anchor point to the dragon. You can  use
     the  "+" and "-" keys to hop the dragon to  either
     end  of the rubber reference line.  F10 will  zoom
     you in and out.

     When  you  are satisfied with the  new  angle  and
     positioning  of the reference line,  press  enter.
     The line is now anchored. The program will ask you
     if  you  wish to Go Back or  Straighten  Page.  To
     begin  the  page rotation, move the black  bar  to
     Straighten Page and press the ENTER key.

     Note:  The larger the angle the program  needs  to
     shift  the  page,  the  longer  it  will  take  to
     complete  the  task.  This is  particullarly  true
     when using the EMS simulator. Larger angles shifts
     may also cause some distortion of the image.
> Saving & Loading Image Files

     When  you initially scan in a page, it is held  in
     your  EMS  simulator or your EMS  card.   At  this
     point, the file has no name.  If you wish to  save
     this  file,  you must assign it a  DOS  compatible
     file name.  To assign, change, or reformat a  file
     name  use the functions available under  the  FILE
     Main Menu.  The LOAD FROM selection allows you  to
     activate  a  graphics file that has  already  been
     saved to hard disk.  The SAVE AS selection  allows
     you to assign a name to a file that has just  been
     scanned.  The SAVE AREA AS selection allows you to
     name  a  boxed area and/or reformat  the  graphics
     file in ATX, PCX, or TIF file forms.  The  DISCARD
     IMAGE allows you to remove the scanned image  from
     your  screen  without  copying  it  to   permanent
     memory.  QUIT AdvanTex exits you from the  program
     and back to the DOS prompt.
> How to Scan

     To scan an image, select the OCR menu then  select
     the  Scan  Page function.  Alternatively  you  can
     simply  press  F3.  The computer  will  now  begin
     scanning.
> Scanning Options

     To  change any of the default  selections,  select
     the "Scanner Settings" control panel.
> Control Panels

     Control  panels are windows which let  you  change
     values which control Advantex.
>  Changing a Control Panel Option:

     Move  the cursor bar to the selection you want  to
     modify  and press the Enter key. Move  the  cursor
     bar  to the new setting you want and  press  Enter
     again.  The setting will change to the  value  you
     selected remain active until you change it  again.
     Scanner   settings  are  stored  in  the   startup
     profile.   activate the scanner, place the  cursor
     over the SCAN selection box, and press Enter.
>  Exiting From a Control Panel

     To  cancel your selections, place the cursor  over
     the  CANCEL  selection box, and press  Enter.   To
     return to the main menu, press ESC.
> Zoom Functions

     The  ZOOM OUT display is a compressed view of  the
     graphics  page that you normally see after a  page
     scan or load. When you wish to take a closer  look
     at a portion of your graphics file,

     1.   Press  the  F9  key to  activate  the  select
          targeting cross hairs.
     2.   Use the CURSOR keys to move the target  cross
          hairs to the desired location on the ZOOM OUT
          display.
     3.   Toggle  between ZOOM OUT and ZOOM IN  at  the
          cross hair point by pressing F10.
> Test Locating Symbols

     The  TEST LOCATE funtion operates on a scanned  or
     loaded  image to locate all symbols  meeting  your
     current  OCR  criteria.

     The  OCR criteria most affecting this function  is
     the spot filter size which determines the size  of
     the  least spot to be considered for OCR  and  the
     maximum  symbol size whic determines  the  maximum
     height  or width of a symbol to be considered  for
     OCR.

     Symbols falling outside of the OCR criteria  range
     are  not  marked and are ignored during  OCR.  The
     bitmap is written on to show the location,  height
     baseline for each line of symbols. You must rescan
     or reload a new image after using this function.
> Test Locating Words

     The  TEST  LOCATE  WORDS  performs  the  OCR  word
     separation function on a scanned or loaded  image.
     This  allows  the  user to  view  Advantex's  word
     separtor  capabilities for the text on  the  page.
     The   word   space   breaking   is   automatically
     recalculated EVERY line and should be accurate  in
     all but the tightest cases (typeset with very very
     small word breaks).

     To run the test use TEST LOCATE WORDS on the  EDIT
     menu.  Each  word  is highlighted  by  writting  a
     halftone  on  the bitmap and the  the  dynamically
     calculated  word  space break criteria.  You  must
     rescan  or  reload a new image  after  using  this
     function.
> Using the Separate Lines Function

     The  SEPARATE LINES funtion operates on a  scanned
     or loaded image to cut lines where the symbols  of
     one  line  accidentally touch the symbols  of  the
     line  following.

     To  use this function set the maximum symbol  size
     to  a  rectangle just taller and  wider  than  the
     biggest single character you want to consider  for
     OCR  (including  the decenders).  The  select  the
     SEPARATE LINES function.  ATX will process the bit
     map  and physically separate the  touching  lines.
     After  separation you can then use the normal  OCR
     functions.
> Handling Accidental Ligatures (Touching Symbols)

     You can handle accidental ligatures two ways.  The
     first  is to add these touching symbols to a  font
     by  training. The second is to enable  or  disable
     the  double  error  marker  (See:  Text   Settings
     Menu)  which outputs two error marker  symbols  on
     detection of a wide error character.
