  132. <h1>Windows Image Acquisition</h1>
  134. <h1><span style='font-size:14.0pt;mso-bidi-font-size:24.0pt;color:red'>[This is
  135. preliminary documentation and subject to change.]<o:p></o:p></span></h1>
  137. <h2>SUMMARY</h2>
  139. <p>This directory contains samples and test tools for Windows Image Acquisition
  140. (WIA), a driver architecture and user interface for acquiring images from still
  141. image devices such as scanners and digital still cameras. This architecture is
  142. currently only supported by Windows Me and Windows XP. These samples will not run
  143. on Windows 2000, Windows 98, or Windows 95.</p>
  145. <h2>CONTENTS</h2>
  147. <p>The following lists the WIA components and samples in the DDK:</p>
  149. <h3>DOCUMENTATION</h3>
  151. <p>Documentation on WIA can be found in the Platform SDK and this DDK. The DDK
  152. contains information on developing drivers, and the Platform SDK contains
  153. information for application writers. Note that WIA properties are only documented
  154. in the Platform SDK under the topic Windows Image Acquisition/Wia
  155. References/WIA Application Programming Interface/Constants/WIA Property
  156. Constants.</p>
  158. <p>Each sample directory contains brief documentation on how to build and run
  159. that sample.</p>
  161. <h3>FLAT-BED SCANNER SAMPLE DRIVER</h3>
  163. <p>The Wiascanr directory contains a sample WIA minidriver for a flat-bed
  164. scanner with a document feeder. See the documentation file <a href="wiascanr\wiascanr.htm">Wiascanr.htm</a>
  165. in the Wiascanr directory for more information. (This sample replaces the old
  166. sample, Wiatscan.)</p>
  168. <h3>SCANNER MICRODRIVER SAMPLE DRIVER</h3>
  170. <p>The Microdrv directory contains a sample WIA microdriver for a scanner. A
  171. microdriver is much easier to develop than a full WIA minidriver, but
  172. provides only basic functionality. See the documentation file <a
  173. href="microdrv\testmcro.htm">Testmcro.htm</a> in the Microdrv directory for
  174. more information.</p>
  176. <h3>DIGITAL STILL CAMERA SAMPLE DRIVER</h3>
  178. <p>The Wiacam and Microcam directories contain a sample WIA driver for a
  179. digital still camera and the Extend directory contains a sample user interface
  180. extension. See the documentation file <a href="wiacam\Wiacam.htm">Wiacam.htm</a>
  181. in the Wiacam directory, <a href="Microcam\Fakecam.htm">Fakecam.htm</a> in the Microcam
  182. directory, and <a href="extend\extend.htm">Extend.htm</a> in the Extend
  183. directory for more information.</p>
  185. <h3>TOOLS</h3>
  187. <p>The Tools\Wia directory in the root directory of the DDK contains additional
  188. tools to help with WIA driver development. Documentation for the tools is
  189. contained in the DDK documentation.</p>
  191. <h2>USING THE SAMPLES</h2>
  193. <p>To quickly build and test all of the samples, run the &#8220;build&#8221; command in the
  194. src\wdm\wia directory using the Free or Checked DDK Build Environment. Then run
  195. the &#8220;copywia.cmd&#8221; batch file to gather all of the binaries into a subdirectory
  196. named &#8220;wiabins&#8221;. The camera and scanner samples can be installed in Windows Me
  197. or Windows XP by using the &#8220;Add Device&#8221; icon in the Scanners and Cameras control
  198. panel. Use the &#8220;Have Disk&#8221; button to point to the wiabins\drivers folder.
  199. Wiatest.exe (from the DDK Tools\Wia directory), MS
  200. Paint, the Scanner and Camera Wizard or any TWAIN application (through the WIA
  201. TWAIN compatibility layer) can be used to test the samples.</p>
  203. <p>For more information on building and using the samples, see the individual
  204. documentation files referenced above.</p>
