<h1><span style='font-size:14.0pt;mso-bidi-font-size:24.0pt;color:red'>[This is

preliminary documentation and subject to change.]<o:p></o:p></span></h1>
|
||
|
|
|
||
|
|
<h2>SUMMARY</h2>
|
||
|
|
|
||
|
|
<p>This directory contains samples and test tools for Windows Image Acquisition
|
||
|
|
(WIA), a driver architecture and user interface for acquiring images from still
|
||
|
|
image devices such as scanners and digital still cameras. This architecture is
|
||
|
|
currently only supported by Windows Me and Windows XP. These samples will not run
|
||
|
|
on Windows 2000, Windows 98, or Windows 95.</p>
|
||
|
|
|
||
|
|
<h2>CONTENTS</h2>
|
||
|
|
|
||
|
|
<p>The following lists the WIA components and samples in the DDK:</p>
|
||
|
|
|
||
|
|
<h3>DOCUMENTATION</h3>
|
||
|
|
|
||
|
|
<p>Documentation on WIA can be found in the Platform SDK and this DDK. The DDK
|
||
|
|
contains information on developing drivers, and the Platform SDK contains
|
||
|
|
information for application writers. Note that WIA properties are only documented
|
||
|
|
in the Platform SDK under the topic Windows Image Acquisition/Wia
|
||
|
|
References/WIA Application Programming Interface/Constants/WIA Property
|
||
|
|
Constants.</p>
|
||
|
|
|
||
|
|
<p>Each sample directory contains brief documentation on how to build and run
|
||
|
|
that sample.</p>
|
||
|
|
|
||
|
|
<h3>FLAT-BED SCANNER SAMPLE DRIVER</h3>
|
||
|
|
|
||
|
|
<p>The Wiascanr directory contains a sample WIA minidriver for a flat-bed
|
||
|
|
scanner with a document feeder. See the documentation file <a href="wiascanr\wiascanr.htm">Wiascanr.htm</a>
|
||
|
|
in the Wiascanr directory for more information. (This sample replaces the old
|
||
|
|
sample, Wiatscan.)</p>
|
||
|
|
|
||
|
|
<h3>SCANNER MICRODRIVER SAMPLE DRIVER</h3>
|
||
|
|
|
||
|
|
<p>The Microdrv directory contains a sample WIA microdriver for a scanner. A
|
||
|
|
microdriver is much easier to develop than a full WIA minidriver, but
|
||
|
|
provides only basic functionality. See the documentation file <a
|
||
|
|
href="microdrv\testmcro.htm">Testmcro.htm</a> in the Microdrv directory for
|
||
|
|
more information.</p>
|
||
|
|
|
||
|
|
<h3>DIGITAL STILL CAMERA SAMPLE DRIVER</h3>
|
||
|
|
|
||
|
|
<p>The Wiacam and Microcam directories contain a sample WIA driver for a
|
||
|
|
digital still camera and the Extend directory contains a sample user interface
|
||
|
|
extension. See the documentation file <a href="wiacam\Wiacam.htm">Wiacam.htm</a>
|
||
|
|
in the Wiacam directory, <a href="Microcam\Fakecam.htm">Fakecam.htm</a> in the Microcam
|
||
|
|
directory, and <a href="extend\extend.htm">Extend.htm</a> in the Extend
|
||
|
|
directory for more information.</p>
|
||
|
|
|
||
|
|
<h3>TOOLS</h3>
|
||
|
|
|
||
|
|
<p>The Tools\Wia directory in the root directory of the DDK contains additional
|
||
|
|
tools to help with WIA driver development. Documentation for the tools is
|
||
|
|
contained in the DDK documentation.</p>
|
||
|
|
|
||
|
|
<h2>USING THE SAMPLES</h2>
|
||
|
|
|
||
|
|
<p>To quickly build and test all of the samples, run the “build” command in the
|
||
|
|
src\wdm\wia directory using the Free or Checked DDK Build Environment. Then run
|
||
|
|
the “copywia.cmd” batch file to gather all of the binaries into a subdirectory
|
||
|
|
named “wiabins”. The camera and scanner samples can be installed in Windows Me
|
||
|
|
or Windows XP by using the “Add Device” icon in the Scanners and Cameras control
|
||
|
|
panel. Use the “Have Disk” button to point to the wiabins\drivers folder.
|
||
|
|
Wiatest.exe (from the DDK Tools\Wia directory), MS
|
||
|
|
Paint, the Scanner and Camera Wizard or any TWAIN application (through the WIA
|
||
|
|
TWAIN compatibility layer) can be used to test the samples.</p>
|
||
|
|
|
||
|
|
<p>For more information on building and using the samples, see the individual
|
||
|
|
documentation files referenced above.</p>
