IMPORTING IMAGES TO OTHER APPLICATIONS

Q1] Why do I sometimes get a black line across the top and bottom or along 
the sides when I import images into PageMaker?

A1]  These symptoms sometimes appear when an image is being saved as a TIFF
at 300 or 400 dpi line-art with a width exeeding 2 inches.  For optimal 
performance importing into PageMaker, save your FotoTouch images as TIFF 
UNCOMPRESSED or PCX.


Q2]  When I try to import FotoTouch documents into WordPerfect, why do I 
sometimes get the message "Invalid File Format."  

A2]  This message is generated when trying to open a TIFF file generated
from FotoTouch.  For optimal performance importing into WordPerfect,
save your FotoTouch images as TIFF UNCOMPRESSED or PCX.

Q3]  How do I use ClipBoard in Windows to take a picture from FotoTouch to 
Other Applications?

A3]  Follow the steps below:
1.  Scan an image and select an area to copy to the Clipboard using 
    the Selection Tool.
2.  Select Copy from the EDIT menu.
3.  Iconize FotoTouch. (Do not Quit or Image will be lost).
4.  Bring forward the other Application and select PASTE from the EDIT menu.

This technique works with images which do not use more than 64K of memory 
to store. For Images which use more memory than this, we recommend saving
the images to whatever format the target application will support.


PRINTING

Q4]  Why is FotoTouch printing blank pages?

A4]  There are a few possibilities:
1.  Bitstream Facelift.  See FaxBack document 2404.
2.  Some non-Postscript printer drivers (notably Hewlett Packard) allow 
you to choose a gray scale option under OUTPUT FORMAT.  Selecting one of
these gray scale options (256 or 64 Gray Scale) will result in a blank
page.  Choose Error Diffused or Dithered instead.


SCANNING 

Q5]  When I start FotoTouch, I receive an "Error Reading Drive D: (or E:)."
What is happening?

A5]  FotoTouch comes with a built in Image Memory Manager (IMM) which works
independently of Windows' built-in memory manager.  Whenever FotoTouch is 
launched, it searches drives C:, D:, and E: for the drive with the most free 
space in order to use this drive for temporary storage of images. This is fine 
in most situations.  However, if you have a non-hard drive (CD ROM, floppy 
drive, etc.) designated as drive D: or E:, FotoTouch will be unable to read 
from this drive.

To correct the problem, go into the WIN.INI file and insert the following 
line in the [Logitech FotoTouch] section :
        
        Temp2=drive:\directory
        (For example, Temp2=C:\WINDOWS\TEMP)

This will instruct FotoTouch to use a specific drive and directory for the 
temporary storage of images and will not do the automatic search.


Q6]  When I select Acquire in FotoTouch, I receive "an error reading drive D:
(or E:)."  What's wrong?

A6]  Whenever you select Acquire from the File menu, you are actually leaving 
the FotoTouch application and starting the ScanMan application. So the Temp2 
line in the WIN.INI file won't work here because we are no longer in 
FotoTouch. The problem is occurring for the same reason but there is a 
different solution along the same lines. Go into the SCANMAN.INI file. About 
14 lines down you will see the following line:
        
        ;Temp2Path=c:\tmp

Remove the leading semicolon (since this means this line is a comment in an 
INI file) and change the drive and directory to a valid directory. 
For example:

        Temp2Path=C:\WINDOWS\TEMP


This will keep the ScanMan software from searching for a drive to use for 
temporary storage.


COMPATIBILITY ISSUES

FotoTouch and the Intel SatisFAXtion Board

Version 2.10 of FotoTouch does not support the ScanMan 256 when plugged into
the Intel SatisFAXtion Card.  If you are using the scanner in this 
configuration and purchased FotoTouch as an upgrade, please make sure
you have version 2.11 of the software.  To verify this version, look at the 
last three digits of the serial number on disk 1 of the FotoTouch disks.  If
it ends with 211, this is the correct version.  If it ends with 210, an 
upgrade will be needed.  Please contact our Sales Information Services
at (800) 231-7717 to obtain further information about this upgrade.


FotoTouch and the Plus HardCard
The Plus HardCard requires a device driver in the CONFIG.SYS file and 
uses IRQ 11, which will conflict with the scanner's default IRQ setting.
Symptoms include system locking when selecting Acquire and drive read errors 
when selecting Acquire. The scanner must be set on another IRQ setting. Go 
into the SCANMAN.INI file and change the interrupt setting (which is at the 
bottom of the file).


PCTOOLS

PC Tools and PC Backup sometimes make changes to the Windows SYSTEM.INI 
file which cause erratic behavior with the Logitech Scanner.  The scanner
will typically work properly in Standard mode, but in Enhanced mode it will
generate an Unrecoverable Application Error in Windows 3.0, or will not
access the scanner in Windows 3.1.

Look for the following lines in the SYSTEM.INI file, in the [386Enh] section:
        
        device=vfd.386
        device=vdmad.386

If these lines exist, then PC Tools has replaced the Windows virtual floppy 
driver and the Windows virtual DMA driver with another version. You can  
reset Windows back to its own drivers by changing the lines to:

        device=*vfd
        device=*vdmad

This will disable the PC Tools backup program. 


Central Point's Anti-Virus

If you run FotoTouch while Central Point's Anti-Virus program is active, you
will receive unexpected results.  Some of the known error messages include 
"Warning! TOUCH.EXE is Being Modified" and "Unexpected DOS Error 5."  After 
displaying the message, the Anti-Virus program will often lock up the 
system.  If you receive these messages, disable the anti-virus software when
running FotoTouch.


ATI Ultra and Vantage Video Cards

These are high performance 8514 compatible video cards. They come with a 
wide variety of video drivers for Windows. One of these drivers is called the 
Crystal Fonts driver. If you are using this driver you will receive colors
in the image instead of grays.  If this occurs, select a different video
driver.


OS/2
In the OS/2 README file there is a listing of applications which are known 
to be problematic or won't function under the OS/2 environment.  Logitech 
Ansel (now upgraded to FotoTouch) and Logitech Perceive are both mentioned 
in this list of programs.

While the applications themselves seem to function under OS/2 2.0, 
incompatibilities occur when accessing or using the scanner. It is simply 
that the hardware device drivers written to support these devices were 
written for the Windows 3.0 or 3.1 environment, not the OS/2 environment.

When we first contacted IBM about problems trying to scan with the ScanMan 
256 in the Windows compatibility box of OS/2, they provided the following 
reasons for this incompatibility:

- FotoTouch cannot work because of an incomplete implementation of OS/2 4B 
interrupt.  (create DOS thread)

- They issued a Corrective Action Request, and said they will correct it in 
the next version.

- They have now a new version supporting the Windows 3.1 compatibility mode, 
and it still does not support our software and scanner interface.

We have been in continuous contact with IBM and are currently working with 
them to try to resolve this issue.  

Logitech does not currently produce an OS/2 scanner or application.  Apart 
from working with IBM to resolve the incompatibilities within the Windows 
compatibility box, we are also investigating the possibility of a scanning 
product which will interface directly with OS/2.  If you are interested in 
seeing such a product on the market, please write and let us know:

Expanded Memory Managers (EMM386 and QEMM) and Standard Mode

On some systems, the presence of an expanded memory manager will conflict
with FotoTouch when run in Windows in Standard Mode.  The symptom is that
no scanner activity is detected when you select Acquire.  The optimum
solution is to run Windows in Enhanced Mode.  If the computer will not
run in Enhanced mode, disable the expanded memory manager.


OTHER ISSUES

MicroChannel Machines (MCA)

If you are using a microchannel computer (PS/2 Model 50 and higher), but 
are not using the ScanMan Model 256, you must have the most recent scanner
board along with FotoTouch.  The application will not function with the
original microchannel board which accompanied the ScanMan Plus.  To obtain
information about upgrading your microchannel board, contact our Sales
Information Services at (800) 231-7717.


Ami Pro Macro for FotoTouch
There are complete instructions on how to install the Ami Pro macro for 
FotoTouch in the TOUCH.SAM Ami Pro document. For instructions on installing
this macro, we recommend reading (and printing out) the entire document.
For the Macro to work, FotoTouch must be running.  If you plan on using 
the macro, first start FotoTouch, then minimize it, then start Ami Pro.
The FotoTouch 2.1 macro will work with Ami Pro 1.2b and 2.0.
