> 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.
