<p class=MsoNormal>This document talks about the Single Document Multiple
Images (SDMI) behavior in TWAIN, describing how it is negotiated and what
additional metadata associated with the image needs to be collected during
image capture.&nbsp; Since this is a moderately complex subject a number of
other capabilities that have uses beyond SDMI will be discussed as well.</p>
<p class=MsoNormal>&nbsp;</p>
<p class=MsoNormal>SDMI behavior is easy to view graphically:</p>

<p class=MsoNormal>In this example a color document results in the capture of
two images, one that is color and one that is bitonal (black &amp; white). Configurations of
this form have a variety of applications, but the most common is when the
application needs a faithful replication of the document for archival purposes
and an image suitable for data collection, such as OCR.</p>
<p class=MsoNormal>&nbsp;</p>
<p class=MsoNormal>SDMI puts no limit on the number of images that can result
from a document.</p>
<p class=MsoNormal>&nbsp;</p>
<p class=MsoNormal>SDMI is not the same as image segmentation.&nbsp; Image
segmentation divides a document into sub-images that are optimized for quality
and compression.&nbsp; In this example the driver could save the text images as
Group-4 and the picture as JPEG:</p>

<p class=MsoNormal>Image segmentation is typically used to efficiently store
images.&nbsp; SDMI is used to capture images that are then directed to
different parts of the workflow.&nbsp; It is possible to mix image segmentation
with SDMI (ex: using image segmentation to produce the faithful replication
image).&nbsp; The two technologies have different goals, though, so it<69>s not
advisable to use one to replace the other.</p>

<p class=MsoNormal>&nbsp;</p>
<p class=MsoNormal>TWAIN did not start with duplex scanning built into the
standard; this was added in version 1.7.&nbsp; So prior to 1.7
<a href="#ICAP_PIXELTYPE">ICAP_PIXELTYPE</a> selected the pixel type (i.e. color
vs. grayscale vs. bitonal) for the entire session. This could also be considered
the &quot;color space&quot;. An application could configure a driver to output
color or grayscale or bitonal images, but only one of the three, so you can not
get multiple images for a side via ICAP_PIXELTYPE. </p>
<p class=MsoNormal>&nbsp;</p>
<p class=MsoNormal>TWAIN 1.8 introduced <a href="#DAT_FILESYSTEM">DAT_FILESYSTEM</a>.&nbsp; This
allows an application to setup multiple images for a side. It also
helps support setting of different values for the front and rear. For example,
getting color on the front and grayscale on the rear.</p>
<p class=MsoNormal>&nbsp;</p>
<p class=MsoNormal>To help maintain backwards compatibility, ICAP_PIXELTYPE needs to
continue to apply to the entire session. This means ICAP_PIXELTYPE should
never be negotiated with DAT_FILESYSTEM.</p>
<p class=MsoNormal>&nbsp;</p>
<p class=MsoNormal>&nbsp;</p>
<p class=MsoNormal>&nbsp;</p>

style='font-family:Arial'>&nbsp;</span></pre>
<p class=MsoNormal>Setting ICAP_PIXELTYPE will set both the front and rear
images to the given TWPT_ value and automatically set CAP_DUPLEXENABLED to true.
Use ICAP_BITDEPTH to determine how many bits make a single pixel, such as 8 for 8-bit
grayscale or 24 for 3-channel/8-bits-per-channel RGB.&nbsp; </p><pre>&nbsp;</pre>

<p class=MsoNormal>DAT_FILESYSTEM addresses individual <20>cameras<61>.&nbsp; The term <20>camera<72> doesn<73>t
mean that the image capture device uses a camera; rather it<69>s a generic term
for an image capture source.&nbsp; DAT_FILESYSTEM calls the front side of the
paper as the 'top' &quot;camera&quot;, and the rear as 'bottom'. This doesn't have
anything to do with the physical position of the camera, it is being used to describe what the user
considers the top (i.e. front) of the sheet of paper versus the bottom (i.e. rear).</p>
<p class=MsoNormal>&nbsp;</p>
<p class=MsoNormal>The driver will output images based on CAP_CAMERAENABLED. So
while a &quot;camera&quot; can be individually set via DAT_FILESYSTEM, you must also set
CAP_CAMERAENABLED to true for each &quot;camera&quot; you want the driver to actually
produce.</p>
<p class=MsoNormal>&nbsp;</p>
<p class=MsoNormal>The values for DAT_FILESYSTEM are typically:</p>

<p class=MsoNormal>The behavior guarantees that older applications and newer
applications can work with the same driver.&nbsp; Application writers need to
decide if they want to use ICAP_PIXELTYPE or DAT_FILESYSTEM
when negotiating with a particular driver, never use both together.&nbsp; As a
guideline, if DAT_FILESYSTEM are supported by a driver, use them,
since they offer more functionality than ICAP_PIXELTYPE.</p>

<p class=MsoNormal>The output order of the images can be adjusted using
CAP_CAMERAORDER (using the CAP_CAMERA TWCM_*_BOTH values).&nbsp; This is a TW_ARRAY
container that has the name of each of the cameras in the order they will be
transferred from the driver to the application.&nbsp; For example, if
CAP_CAMERAORDER is set to TWCM_BW_BOTH TWCM_CL_BOTH, then the bitonal image
will be transferred before the color image.&nbsp; For a duplex session this
would look like the following:</p>
<p class=MsoNormal>&nbsp;</p>
<p class=MsoNormal>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Bitonal Front</p>
<p class=MsoNormal>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Color Front</p>

<p class=MsoNormal>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Color Rear</p>
<p class=MsoNormal>&nbsp;</p>
<p class=MsoNormal>To simplify the validation rules between CAP_CAMERAENABLED and

</span>If CAP_CAMERAORDER does not include a &quot;camera&quot; that is set to True,
then the driver is free to output the images in whatever ordering it wants.</p>

style='font-family:Arial'>&nbsp;</span></pre>
<p class=MsoNormal>The addition of independent front and rear capability
negotiation immediately raises the question: which capabilities belong to the
machine (like CAP_DUPLEX) and which ones belong to a &quot;camera&quot; (like CAP_COMPRESSION).&nbsp; There is no easy answer to this, since the hardware of
the device dictates the capabilities.&nbsp; For instance scanner ABC may allow
independent selection of ICAP_COMPRESSION for front and rear cameras because
the designers put in dedicated compression chips for each side.&nbsp; Whereas
scanner XYZ, in an effort to save costs, only used one chip for this operation,
and they have no way to independently set the front from the rear for this one
capability.</p>
<p class=MsoNormal>&nbsp;</p>
<p class=MsoNormal>So, to help figure out where each capability goes, Kodak
scanners have enhancement DG_CONTROL / DAT_CAPABILITY /
MSG_QUERYSUPPORT with additional TWQC_ flags:</p>

<p class=MsoNormal>&nbsp;</p>
<p class=MsoNormal>Capabilities
that describe themselves as TWQC_MACHINE are accessible at all times,

style='font-size:12.0pt;font-family:Arial'><a name="METADATA">METADATA</a></span></b></pre><pre>&nbsp;</pre>
<p class=MsoNormal>Metadata is the descriptive data that accompanies an
image.&nbsp; TWAIN has two primary ways of communicating this information to an
application: DAT_IMAGEINFO and DAT_EXTIMAGEINFO.&nbsp; Since DAT_EXTIMAGEINFO
is extensible it<69>s the only way to introduce new metadata items to the TWAIN
specification without creating a new DAT operation (and we don<6F>t really need
any more of those right now).</p>
<p class=MsoNormal>&nbsp;</p>
<p class=MsoNormal>SDMI presents a bit of a problem for the application because
the stream of images makes it difficult to tell which ones go with which
document.&nbsp; This problem becomes compounded with things like
automatic color detection (imagine not knowing if the
application will get color or bitonal data on the next image).</p>
<p class=MsoNormal>&nbsp;</p>
<p class=MsoNormal>Since the problem takes the form of a lack-of-communication
problem, the solution is more data.&nbsp; With the Kodak drivers the following
