In order to make full use of the HANDY-READER, you either need a HANDY-
SCANNER of CAMERON GmbH, the Mitsumi A4 Scanner or the Gerdes Personal A4
Scanner.
---------------------------------------------------------------------------
This file informs you about the recent improvements and changes concerning
the HANDY-READER. We'd also like to make suggestions for solving problems
of general interest. If you have any comments on the HANDY-READER write a
short letter to CAMERON GmbH.
---------------------------------------------------------------------------
Version 3.04 dated on 05/06/90 is the sixth release-version of HANDY-READER
for the Commodore AMIGA. It replaces version 3.03 from 04/02/90. A fourth
version (3.02) was released on 09/25/89. The third version (3.01) originated
on 05/08/89. The second version (3.0) was dated 11/21/88. The first Version
(2.0) was dated 07/21/88.
The following bugs have been corrected:
- If you defined an area that was larger than your scan version 2.0 sometimes
crashed while recognizing. This does not happen any more. 3.0
- Handy-Reader had problems with some of the Personal A4 Scanners. It
started scanning about 2.8 cm from the left border. This does not happen
any more. 3.01
- A bug in the recognition-algorithm sometimes caused incorrect recognition
or hang-ups. This has been fixed. 3.01
- If you had a Commodore AMIGA with more then 2.5MByte and used a Handy-
Scanner in 200dpi mode Handy-Reader could not believe in the amount of
free memory and crashed. The overflow that caused this problem will not
occur any more. 3.02
- In case you have several programs running at the same time Handy-Reader
will now correctly ignore mouse movements on other screens. 3.02
- There were apparently not sensible line feeds in long lines with large
characters because one buffer was too small. This bug has been corrected
by doubling the size of the buffer which should be sufficient for all
sensible cases. 3.03
- During teach-in it happened that Handy-Reader learned empty strings
instead of valid characters due to a programming error. This bug has been
fixed. 3.04
The following improvements have been made:
- HANDY-READER now also supports the 200dpi DINA4-Scanner "Personal Scanner".
HANDY-READER tests which scanner is connected and takes appropriate steps.
Double resolution is not possible with this scanner. If you want to scan a
complete DINA4-page you must have at least 1MByte RAM. It is advisable not
to use the second scan-buffer or to have it on disc. (see also below)
HANDY-READER had also to be adapted in order to be able to cope with the
amount of text you might find on a whole A4 page. Memory management was
modified, too, because a complete A4 page was to be scanned into an AMIGA
with exactly 1MByte RAM. 3.0
- Handy-Reader now also supports the Handy-Scanner type 10 (105mm wide, 200/
300/400dpi resolution) as well as the Mitsumi A4 Scanner (200/300dpi in up
to 64 dithering-gray-scales). If you want to use one of these scanners you
need the apropriate interface. 3.02
- In case of an error which forces Handy-Reader to exit to DOS Handy-Reader
now tries to display the cause of the error using an Alert. Thus you
should be informed about the cause of the error even if you started
Handy-Reader via Workbench. 3.03
- If you have not much free memory you do not always have to use the full
scan-width. `ow there is a new menu item ("Set scan-width limit") which
enables you to limit the width of the scan-in. Selecting this item allows
you to enter the maximum scan-width in mm. This width will be used at
maximum (starting from the left border of the original) when scanning. If
you do not want to have a limitation of the scan-width, you simply have to
enter a "?". 3.02
- The menu "Font data" has been extended by "Teach & Recog". This is a combi-
nation of "Teach-in" and "Recognize"; it might be called a very sophisti-
cated teach-in. It is used similary - especially the definition of an area
- to the functions quoted above. HANDY-READER starts to translate the text
into ASCII if you have called this function. In case it is not sure about
a character it will ask you the correct interpretation. Thus you get your
original translated and you improve your database in one pass. Nonetheless,
a simple "Recognize" is faster than this function (if you want nothing but
a translation) and if HANDY-READER mixes characters up you will still have
to use "Teach-in" in order to correct these faults. Anyway, this function
is a very interesting addition to our HANDY-READER and it will certainly
replace the "Teach-in" in most cases. 3.0
- You will find two new menu-items below the titel "Scanner". The first one
is "Scan must be restored". You can use it in order to specify if you
need a backup of the original picture or not. The backup serves for re-
storation of the picture after recognition. Horizontal scanning is only
possible if you have a backup of your picture. HANDY-READER tries to make
a backup-copy nonetheless and only works without it if this is not
possible. 3.0
- The second new item is "Disc may be used". This tells HANDY-READER if the
backup may be stored on disc or must be kept in memory. If the backup is
on disc HANDY-READER will certainly need more time than if it were in
memory and there must be enough free space on the disc you use. The disc
will only be used if there is not enough space in memory. The name of the
backup-file can easily be changed in "Text.txt" with an ASCII-Editor. 3.0
- Another new menu-item is "Find text areas" under the title "Recognize".
This works like "Recognize". HANDY-READER just tries to find sensible
passages of text on its own. Thus three columns with a title in full width
can be translated in one pass. Output is in the same order as you would
read the text. 3.0
- New under the same heading is also "Font size". If you know the font size
of your original you may enter it here. Knowing the correct size will im-
prove the quality of the recognition. If you do not know the size you may
enter something like a "?". The fonts of a typewriter normally are 10 to
12 point high.
Attention: Many small fonts that are supposed to be 12 point high are only
about 11 pt. high. In this case the next function might help you. 3.0
- Closely connected to the previous menu item is "Help font size". If you do
not know the correct font size you can use this function to find out how
large your font is. Before calling this function you must look for an
uppercase (!) letter and define a frame around it. The frame is defined in
the same way as an area for text recognition. Now you may select this menu
item and your computer will tell you the estimated size of the font on
your original. If used properly this estimated size is much more exact
than the knowledge of the font size from other sources. In the first place
you have to be careful when drawing your scanner (if you have a HANDY-
SCANNER), then you should indeed select an uppercase letter and the frame
must fit exactly around your character. 3.0
- Now some options follow that you can use to specify parameters for text
recognition. The first option is "+ Divide chars" under the title "Recog-
nize". It selects whether several connected characters shall be divided or
not. If you have an original that does not have any connected chars at
all, you should switch this off. This will improve the certainty of recog-
nition a little bit. 3.0
- The second parameter is "+ Remove frames". Normally HANDY-READER auto-
matically removes large graphics like frames around text passages. If you
do not have any of this kind at all you can switch this option off. In
cases of different font sizes or many connected characters you will get
better results when switching it off. 3.0
- At the moment the last new menu item is "+ Exact" under the title "Recog-
nize". You can use it to select two different ways of recognition: 'Draft'
and 'Exact'. The font data for these two degrees of exactness is not
compatible. Draft is equivalent to what HANDY-READER 2.0 worked with.
With Exact you will get a much higher reliability but you pay for it by
gettuing font size dependent (meaning that you need new font data for each
size), slower and the maximum size of the database is smaller (about 1600
compared to 2800 entries). When loading a font data file exactness will be
changed properly if necessary. Always when you change the exactness any
data still in memory has to be cleared. If this happens, HANDY-READER 3.0
will ask the user whether to proceed or not. We have already provided you
with some fonts for Exact. They are Courier, Prestige, Pica, LetterGothic
in '12pt.'. You should start off using them in order to create you own
data bases. Only if you do so you will ever get more than 99% of your text
translated correctly.
MERGE and LISTER have of course been adapted, too. As the Draft- and Exact-
Files are not compatible MERGE will not work with font data files of
different type. LISTER will also tell you the type of your font data file
beside all the other information it provides you with. 3.0
- Handy-Reader now differenciates much better between lines. 3.0
- The maximum scanlength is saver, so memory should'nt get rare so fast. 3.0
- Starting Handy-Reader and loading a datafile has become more easy because
Handy-Reader now also searches the directory DATA. The same applies to
MERGE and LISTER as well. Only the destination name of MERGE must always be
given complete including the path name. 3.0
