ΓòÉΓòÉΓòÉ 1. Extended Help for ReView ΓòÉΓòÉΓòÉ

The ReView program is a document imaging tool for scanning, viewing and
indexing bitmap images.  Help is available any time you press the F1 key from
anywhere within the program.  Because this is context sensitive help, the help
information that is displayed depends on where in the program F1 was selected.

For instance, you receive help for the File pull-down on the action bar when
you highlight File and press F1.  However, this is not the same help that is
displayed when you press F1 while the Open Documents choice in the File
pull-down is highlighted.

Press Esc at any time to view the previous help window or to return to the
ReView window if there are no other help windows.


ΓòÉΓòÉΓòÉ 2. Help for Database Access ΓòÉΓòÉΓòÉ

 From the Document Access Window, the user may Add, Delete, Edit, Search, or
View documents.  The currently selected folder contents are displayed in a list
covering most of the window.  To perform any action on an existing document, it
must be selected (indicated by inverse colors).  To select a document, the user
clicks the left mouse button while pointing to the document of interest.  While
selected, the user may View, Delete, or Edit the document.  A shortcut to view
a document is to double-click on the document name.  To view the contents of a
different folder, select a folder from the folders drop-down list.  After
selecting a folder, All of the documents in the folder will be displayed.  To
search for specific documents, click on the Search button and enter a keyword
to find. You may select the sort method from this dialog also.


ΓòÉΓòÉΓòÉ 3. Help for Acquire New Documents ΓòÉΓòÉΓòÉ

 Documents are composed of one or more pages. Pages may be imported from
existing image files or faxes, or received from a supported scanner.  The pages
which are joined together to form a document may be combined from any source in
any order. For example, a document may have a fax as its first page followed by
ten pages received from a scanner.  New documents are created by using the
Acquire New Documents window as described below.  To open the Acquire Documents
window click on the  icon on the toolbar.  You may get images from arbitrary
files (including bitmaps and faxes) by pressing the Import button, or from a
TWAIN compatible scanner if one is connected to the system.  Each page, as it
is acquired, will appear as a thumbnail view in the window.  A blue square
indicates the starting page of a selected range (red is used to indicate the
ending page).  By pressing the left mouse button, the user may select the
starting page.  By double-clicking the left mouse button, the user may view a
page in the viewing window.  Clicking the right mouse button will select the
ending page of a range of pages.  A range of pages indicates which pages will
be Deleted, or Stored to form a document.  If no pages are selected, all pages
will be considered selected.  If the ending page is not specified, it will be
assumed that the last page available is this page.


ΓòÉΓòÉΓòÉ 4. Help for File ΓòÉΓòÉΓòÉ

Use the File pull-down choices, or the toolbar to:

Open Document... Display the Document Access Window.

Open File... Display an image file in the viewer.

Export Page... Save the current page to an image file.

Print... the current document or image file.

or Exit the program.  When ReView starts, the menu items Export Page..., Close,
and Print... will be grayed out.  These items will become available when a
document or file is open in the viewer.


ΓòÉΓòÉΓòÉ 5. Help for Open Document... ΓòÉΓòÉΓòÉ

Use this icon or menu item to open the Document Access window.  From here, you
may select a document for viewing.


ΓòÉΓòÉΓòÉ 6. Help for Open File... ΓòÉΓòÉΓòÉ

Use this menu item to open an image file.  ReView will automatically detect the
file type such as GIF, TIFF, and open a view of the first page. Use this option
to view FAXes or other images that have not been added to the database.


ΓòÉΓòÉΓòÉ 7. Help for Close ΓòÉΓòÉΓòÉ

Use this menu item to close the current file and free the memory associated
with the displayed image.  If scanning large color images, this option might be
necessary to prevent the swapper file from becoming too full.


ΓòÉΓòÉΓòÉ 8. Help for Export Page... ΓòÉΓòÉΓòÉ

Use this menu item to save the currently displayed page.  If modifications were
done to the image such as rotation, the image will be saved the way it appears.
Images may be saved in a variety of formats to facilitate exchanging files
between applications. If a multipage document is open, only the current page is
saved.


ΓòÉΓòÉΓòÉ 9. Help for Batch Convert... ΓòÉΓòÉΓòÉ

Use this menu item to convert a directory full of image files from one format
to another.  Any valid image files in the source directory will be converted
from any source format to a specified destination format.  Any of the image
manipulation options of ReView such as rotation can be performed on the images
during conversion.  An option exists to delete the source image files after
successful conversion.


ΓòÉΓòÉΓòÉ 10. Help for Print... ΓòÉΓòÉΓòÉ

Use this icon or menu item to print a range of pages to a graphics printer.
The three print options are useful for the following conditions:

Fit to page If the image is larger or smaller than the printed page supports,
this option will shrink or stretch the image as necessary to cover the majority
of space on the page.

Actual Size If the image width is 1000 pixels at 200dpi, it occupied five
inches when it was created; this option will stretch or shrink the image to
that it would be five inches wide on the printer as well.

One-to-one When printing dithered images, stretching or shrinking the image can
produce unwanted patterns or distortions.  Use this option to guarantee that
one document pixel becomes one printer pixel.  This is also useful when the
source images' resolution information is not correct.


ΓòÉΓòÉΓòÉ 11. Help for Exiting ReView ΓòÉΓòÉΓòÉ

Use this menu item to end the ReView program.  If modifications were made to an
image being viewed, they will not be saved automatically.  If any pages are
remaining in the Acquire New Documents Window, you will be prompted before they
are deleted.


ΓòÉΓòÉΓòÉ 12. Help for Edit ΓòÉΓòÉΓòÉ

Use the Edit pull-down choices, or the toolbar to:

Copy the selected region to the clipboard.

Paste the clipboard contents to become the new image.

Copy Page being viewed to the clipboard.

Crop the current page to the selected area.

Rotate the current page 90, 180 or 270 degrees.

Invert the colors of the current page.

Flip Vertical

Flip Horizontal

Scale to FAX the current page if it is monochrome.

Scale x2 the current page if it is monochrome.

Update Thumbnail Send modifications back to the page in the Acquire Window.


ΓòÉΓòÉΓòÉ 13. Help for Copy ΓòÉΓòÉΓòÉ

Use this icon or menu item to copy the contents of the selection rectangle to
the OS/2 Clipboard.  If the clipboard had any data in it, it will be
overwritten by the new data.  This menu item will only be available when a
selection rectangle exists, otherwise it will be disabled.


ΓòÉΓòÉΓòÉ 14. Help for Paste ΓòÉΓòÉΓòÉ

Use this icon or menu item to create a new document from the contents of the
OS/2 Clipboard.  This menu item will only be available when bitmap data is
present in the clipboard, otherwise it will be grayed out. If there was page
being viewed, it will be replaced by the contents of the clipboard.


ΓòÉΓòÉΓòÉ 15. Help for Copy Page ΓòÉΓòÉΓòÉ

Use this menu item to copy the entire page being viewed to the OS/2 clipboard.


ΓòÉΓòÉΓòÉ 16. Help for Crop ΓòÉΓòÉΓòÉ

Use this menu item to crop the current page to the selection rectangle. The
selected area will become the current page.  This menu item will only be
available when a selection rectangle is present.


ΓòÉΓòÉΓòÉ 17. Help for Resize ΓòÉΓòÉΓòÉ

Use this menu item to change the size of the current page.  The height and
width of the image can be changed independently to produce non-proportional
shrinking or stretching of the bitmap.  This option is only available for color
images.


ΓòÉΓòÉΓòÉ 18. Help for Invert ΓòÉΓòÉΓòÉ

Use this icon or menu item to invert the color of the currently open page.
This will turn all white pixels to black and all black pixels to white.  The
actual page is modified not just the view.  If the page is saved, it will be
saved the way it is displayed.


ΓòÉΓòÉΓòÉ 19. Help for Flip Vertical ΓòÉΓòÉΓòÉ

Use this icon or menu item to flip the current page top to bottom.  The actual
page is modified not just the view.  If the page is saved, it will be saved the
way it is displayed.


ΓòÉΓòÉΓòÉ 20. Help for Flip Horizontal ΓòÉΓòÉΓòÉ

Use this icon or menu item to flip the current page left to right (mirror
image).  The actual page is modified not just the view.  If the page is saved,
it will be saved the way it is displayed.


ΓòÉΓòÉΓòÉ 21. Help for Scale to Fax ΓòÉΓòÉΓòÉ

Use this menu item to scale the current image to fit in the standard fax width
of 1728 pixels horizontally.  This option is only available for monochrome
images since they may be saved in FAX compatible files. This option is useful
for images that were scanned at a higher or lower resolution than the standard
fax resolution (200 dpi).  Both the horizontal and vertical directions are
scaled proportionately so as not to distort the aspect ratio of the original
image. Because of the technique ReView uses to scale images, very little image
degradation should be noticeable after performing this function.  The actual
page is modified not just the view.  If the page is saved, it will be saved the
way it is displayed.


ΓòÉΓòÉΓòÉ 22. Help for Scale x2 ΓòÉΓòÉΓòÉ

Use this menu item to scale the current image to twice its original size in
both the x and y directions.  Because of the way ReView stores images
internally, this option is only available when viewing monochrome images. This
option is useful for changing the target resolution of an image.  The actual
page is modified not just the view. If the page is saved, it will be saved the
way it is displayed.


ΓòÉΓòÉΓòÉ 23. Help for Rotate ΓòÉΓòÉΓòÉ

Use this menu item to rotate the image by 90, 180 or 270 degrees.  This option
is useful for fixing images that have been scanned upside-down (180 degrees),
or sideways (90,270 degrees).  The actual page is modified not just the view.
If the page is saved, it will be saved the way it is displayed.


ΓòÉΓòÉΓòÉ 24. Help for Rotate 90 degrees ΓòÉΓòÉΓòÉ

Use this menu item to rotate the image by 90 degrees clockwise.  This option is
useful for fixing images that have been scanned sideways. The actual page is
modified not just the view.  If the page is saved, it will be saved the way it
is displayed.


ΓòÉΓòÉΓòÉ 25. Help for Rotate 180 degrees ΓòÉΓòÉΓòÉ

Use this menu item to rotate the image by 180 degrees.  This option is useful
for fixing images that have been scanned upside-down. The actual page is
modified not just the view.  If the page is saved, it will be saved the way it
is displayed.


ΓòÉΓòÉΓòÉ 26. Help for Rotate 270 degrees ΓòÉΓòÉΓòÉ

Use this menu item to rotate the image by 270 degrees clockwise.  This option
is useful for fixing images that have been scanned upside-down and backwards.
The actual page is modified not just the view.  If the page is saved, it will
be saved the way it is displayed.


ΓòÉΓòÉΓòÉ 27. Help for Update Thumbnail ΓòÉΓòÉΓòÉ

When a page from the Acquire New Documents Window is displayed in the main
viewer window by double-clicking on it, a new and independent copy of the image
is what is displayed.  You may make modifications to the image in the viewer,
but for them to affect the page in the Acquire Window, changes must be sent
back with this option.  After you have completed all modifications to the image
in the viewer, use this option to send those changes to the page in the Acquire
Window.


ΓòÉΓòÉΓòÉ 28. Help for Administration ΓòÉΓòÉΓòÉ

Use the Administration pull-down choices to:

Configure... the scanner and drive for where documents will be stored.

Maintenance... Or perform maintenance on the database or documents.


ΓòÉΓòÉΓòÉ 29. Help for Configure ΓòÉΓòÉΓòÉ

Before creating documents, you must define which drive the database will reside
on, which drive will be the default document drive, and which drive temporary
images created during the acquire process will be stored on. Each folder may
reside on a different drive, but the default drive will be used if a different
one is not specified at the time a folder is created.  This dialog will also
allow you to select which TWAIN source (scanner driver) will be in use for
scanning in new documents.  (See the ReView user guide for instructions on how
to use the scanner drivers).


ΓòÉΓòÉΓòÉ 30. Help for Keyboard ΓòÉΓòÉΓòÉ

 The following keys are recognized by the ReView image viewer:

o F1 - Pressing F1 at any time will display a context sensitive help panel;
  this includes menu items and dialog boxes.

o Arrow keys - These keys are used to pan around the document currently being
  viewed.

o Pg Up/Pg Dn - When viewing a page which does not fit completely within the
  window, these keys will advance the current view a screen-full up or down.

o + - Has the same effect as clicking on the zoom-in icon or menu item.

o - - Has the same effect as clicking on the zoom-out icon or menu item.

o ESC - Exits from all dialogs the same as pressing the CANCEL button.


ΓòÉΓòÉΓòÉ 31. Help for Maintenance ΓòÉΓòÉΓòÉ

Use this menu item to perform various maintenance functions on the database and
documents, such as:

o Copy the contents of a folder.

o Delete the contents of a folder.

o Regenerate the database index from the individual image files.


ΓòÉΓòÉΓòÉ 32. Help for View ΓòÉΓòÉΓòÉ

Use the View pull-down choices, or the toolbar to:

Next Page Go to the next page.

Previous Page Go to the previous page.

Goto Page... Go to a specific page.

100% Scale the view to 100%.

Fit to Width Scale the view to fit the width of the window.

Fit to Window Scale the view to fit entirely in the width.

Zoom Out Zoom to a wider view by 10%.

Zoom In Zoom to a narrow view by 10%.


ΓòÉΓòÉΓòÉ 33. Help for Next Page ΓòÉΓòÉΓòÉ

Use this icon or menu item to go to the next page of a multi-page document.  If
the document contains only one page, this option will not be available.


ΓòÉΓòÉΓòÉ 34. Help for Previous Page ΓòÉΓòÉΓòÉ

Use this icon or menu item to go to the previous page of a multi-page document.
If the document contains only one page, this option will not be available.


ΓòÉΓòÉΓòÉ 35. Help for Goto Page ΓòÉΓòÉΓòÉ

Use this icon or menu item to go directly to a specific page in a multi-page
document.  If the document contains only one page, this option will not be
available.


ΓòÉΓòÉΓòÉ 36. Help for 100% ΓòÉΓòÉΓòÉ

Use this icon or menu item to show the currently open page at a 100% scale.
100% in this case means that one document pixel corresponds to one screen
pixel.


ΓòÉΓòÉΓòÉ 37. Help for Fit to Width ΓòÉΓòÉΓòÉ

Use this icon or menu item to show the currently open page so that it fits
entirely within the width of the viewing window.  This option is useful for
scanned documents containing text.  Because of the scaling technique used by
ReView, a typical fax document can be legible when viewed on a VGA display with
this scale.


ΓòÉΓòÉΓòÉ 38. Help for Fit to Window ΓòÉΓòÉΓòÉ

Use this icon or menu item to show the currently open page so that it fits
entirely within the viewing window.  This option is automatically chosen when a
document is first opened or pasted into ReView.


ΓòÉΓòÉΓòÉ 39. Help for Zoom In ΓòÉΓòÉΓòÉ

Use this icon or menu item to zoom in by 10%. The view will narrow, but remain
centered on the original spot as you zoom in farther and farther.  You may zoom
until the displayed image is 100% its original size. Clicking on the toolbar
icon will perform the same action as selecting the Zoom In menu item.


ΓòÉΓòÉΓòÉ 40. Help for Zoom Out ΓòÉΓòÉΓòÉ

Use this icon or menu item to zoom out by 10%. The view will widen, but remain
centered on the original spot as you zoom out farther and farther.  You may
zoom until the displayed image is 10% its original size. Clicking on the
toolbar icon will perform the same action as selecting the Zoom Out menu item.


ΓòÉΓòÉΓòÉ 41. The Options Menu ΓòÉΓòÉΓòÉ

Use the Options pull-down choices to set Preferences,  convert the current
image to Gray, Modify the bits per  pixel, and Lighten or Darken the image.


ΓòÉΓòÉΓòÉ 42. Help for Preferences ΓòÉΓòÉΓòÉ

Use this menu item to display the Preferences dialog box.  You many choose the
default view scale (when each page loads), the contrast level used for drawing
monochrome images, and which user interface features to enable or disable.  As
the mouse is moved over the toolbar or menu items, a help message will be
displayed in the status line at the bottom of the screen.  This feature may be
disabled by unchecking one of the user interface checkboxes.  You may also
choose whether or not to display the status line and toolbar.


ΓòÉΓòÉΓòÉ 43. Help for Color->Gray ΓòÉΓòÉΓòÉ

Use this menu item to change the current image from color to grayscale. This
option will modify the palette of a 4 or 8 bpp image, or directly modify the
content of a 24 bpp image.  Selecting this function a second time will have not
effect since the image will already have been converted to gray.  The intensity
for each color is computed as follows: 25% red, 50% green, 25% blue. These
values are summed to produce an intensity level with R=G=B.


ΓòÉΓòÉΓòÉ 44. Help for Color Modification ΓòÉΓòÉΓòÉ

Use this menu item to change the number of bits per pixel of the current page.
You may convert an image to more or less bits per pixel. Converting an image to
more bits per pixel may sound like a useless option, but there are times when
you would like to add more color to an image than was there previously.  For
example, if you would like to add color to a monochrome image, the majority of
paint programs will only let you edit it in black and white.  With ReView, you
can first convert the bi-level image to a 16-color image, then use your
favorite paint program to add color. When converting an image to 4bpp
(16-colors) the default VGA palette will be used since the majority of times,
this is the desired target palette.  When converting to fewer bits per pixel,
you may choose one of three options:

1) Best Color Choices - This option will simply pick the best match for each
color in the target bit density. This is the fastest option, but will usually
give the least desirable results.

2) Ordered Dither - This option uses a Bayer ordered dither pattern to reduce
the number of colors.  This option is quick and will give reasonable results,
but will have a noticeable pattern in the output.  This is sometimes the best
option for doing black and white printouts.

3) Error Diffusion - This option uses a Floyd-Steinberg error diffusion filter
to reduce the number of colors.  This is the most processor intensive option,
but will yield the most visually pleasing results of the three.  The resulting
image will have a slight graininess to it, but there should be no noticeable
pattern to the dots.

After using any of the above options, the image will probably appear distorted
if viewed at a zoom of anything other than 100%.  This is because the pattern
of dots must be fully intact to see the image correctly.  When viewing at a
scale other than 100%, some of the pixels must be ignored in order to squeeze
the entire image into fewer pixels.  Click with the right mouse button to zoom
in to 100% if the image looks strange after conversion.


ΓòÉΓòÉΓòÉ 45. Help for Brighten ΓòÉΓòÉΓòÉ

Use this menu item to increase the overall brightness of an image. If the image
is 4 or 8bpp, the palette entries will be modified, not the image data itself.
For systems will 16-color displays, the change will not necessarily be
noticeable since the video display is limited to a fixed set of colors. Systems
with 256 or more colors on the video display will see the change immediately.
For 24bpp images, the original image data will be modified since there is no
color palette.


ΓòÉΓòÉΓòÉ 46. Help for Darken ΓòÉΓòÉΓòÉ

Use this menu item to decrease the overall brightness of an image. If the image
is 4 or 8bpp, the palette entries will be modified, not the image data itself.
For systems will 16-color displays, the change will not necessarily be
noticeable since the video display is limited to a fixed set of colors. Systems
with 256 or more colors on the video display will see the change immediately.
For 24bpp images, the original image data will be modified since there is no
color palette.


ΓòÉΓòÉΓòÉ 47. Help for Photo CD Options ΓòÉΓòÉΓòÉ

Since Photo CD images contain several resolutions simultaneously, it is
necessary to choose a resolution before loading the image.  The choice of bit
densities is given because the poster sized image (3072x2048) can consume a
huge quantity of memory and by loading a grayscale image, it not only uses less
memory, but it can be loaded much more quickly.


ΓòÉΓòÉΓòÉ 48. Help for Regenerating the Index ΓòÉΓòÉΓòÉ

If, for some reason, the ReView database is deleted or corrupted, it is
possible to regenerate the database from the document images.  Each document is
stored as a multipage image file with it's database record appended to the end
of the file.  After specifying a drive letter, this function will search all
directories below IMAGES and re-create all of the folders and document info in
the database.


ΓòÉΓòÉΓòÉ 49. Help for Delete Folder ΓòÉΓòÉΓòÉ

This option allows one to delete all the documents in a folder and the folder
itself.  The image files associated with each document are permanently deleted
can cannot be restored after this operation.  Choose a folder name from the
list presented and click OK to delete the folder.


ΓòÉΓòÉΓòÉ 50. Help for Copy Folder ΓòÉΓòÉΓòÉ

This option allows one to make a copy of all the documents in a folder for
backup purposes or to transfer to another machine.  Select a folder from the
list presented and type a destination drive letter.  The image files will be
copied to the destination drive and may be added to another database by doing a
database regenerate on that system.


ΓòÉΓòÉΓòÉ 51. Help for Search ΓòÉΓòÉΓòÉ

The Search dialog serves two purposes:

o To select the sort criteria for documents displayed in the Document Access
  window.

o To search selected fields which match a given keyword.

After typing in a keyword, the display option will automatically be set to
matching and a search will be done when OK is clicked.  To redisplay the entire
contents of a folder, click the all radio button.


ΓòÉΓòÉΓòÉ 52. Help for Creating a new document ΓòÉΓòÉΓòÉ

When creating a new document, several of the fields are required, others are
optional and will use default data if none is entered.  The following are the
required fields:

o Document Name - The document must be unique and can be up to 20 characters in
  length.

o Description - The description field can be up to 60 characters in length.
The following fields are optional:

o Original Date - This field represents the date that the information was
  actually created.  The date the document was created is automatically entered
  by ReView.  If no date is entered, the date 7/4/1776 is used to place the
  document at the end of the list if the list is sorted in date order.

o Keywords - Up to 32 characters of keywords may be entered.  Keywords should
  be separated by spaces and can be used to find documents from the Search
  dialog.

o Comments - Up to 128 characters may be entered in the comments field.

o Author - Up to 20 characters may be entered for the author name.  If no name
  is entered, the name ZZZ is used to place the document at the bottom of the
  list when sorted by author.

The two checkboxes at the bottom of the dialog are useful when creating a
succession of documents with similar information.  The auto unique feature will
increment a number on the end of the document name.


ΓòÉΓòÉΓòÉ 53. Help for Editing a document ΓòÉΓòÉΓòÉ

All of a document's data fields may be edited.  To add or removed pages from an
existing document, click on the re-acquire button which will separate the
document into all of its pages in the acquire window.  The pages may then be
re-combined with new pages to form a new document.


ΓòÉΓòÉΓòÉ 54. Help for Creating a new folder ΓòÉΓòÉΓòÉ

Enter a unique name for each folder up to 20 characters in length.  Each folder
may reside on a different logical drive.  The drive letter will initially be
the default documents drive, but may be changed to any valid drive.


ΓòÉΓòÉΓòÉ 55. Help for Acquire options ΓòÉΓòÉΓòÉ

These three options govern the following behavior:

o When acquiring new pages either from a scanner or from imported files, each
  page will normally be added to the end of the list.  When the insert box is
  checked, pages will be inserted at the current selection point (the blue
  outline).  After the next set of pages are scanned or imported, the option
  will automatically be unchecked.

o ReView may be used to create multipage image files from scanned or imported
  files instead of storing them in the database.  When the save to file option
  is checked, the Store button will allow saving the pages to a file instead of
  a document.  This option will automatically be unchecked after a file is
  saved.

o When scanning two-sided documents on a scanner which only scans one side of
  the page, it will be necessary to scan a range of pages and then flip them
  over to scan the other side.  Checking the duplex option will store a range
  of pages with the assumption that they have been scanned in this manner. For
  example, a set of 8 double-sided pages would be scanned in the following
  order: 1,3,5,7,8,6,4,2.  Checking this option will re-arrange the pages when
  they are stored in a file or document.  This option will automatically be
  unchecked after a file or document is stored.
