[VBnet Imaging] Microsoft Windows Image Acquisition Library v2.0 for XP

Developers wanting to add image and image device control functionality to their applications will and to check out this new, redistributable dll provided by Microsoft intended to replace functionality introduced with the Wang and Kodak image controls provided in older versions of Windows. Prior to the introduction of Windows XP, the Wang/Kodak control and libraries formed part of the operating system installation (were not redistributable) and provided the only inherent means to offer imaging display and manipulation without relying on third-party controls. However, Kodak Imaging for Windows program and the related controls (ImgScan.ocx, ImgAdmin.ocx, ImgEdit.ocx, and ImgThumb.ocx) are not included with Windows XP.

The readme file indicates the Windows Image Acquisition Library v2.0 is only designed to support the PNG, BMP, JPG, GIF and TIFF image formats. It should not be relied upon to support other formats, though they may appear to be supported depending on system configuration.

The download contains the dll, help files, installation instructions and a rash of assorted VB-based demos (and no, it does not contain the image shown ... that's my desktop background):

VB6 Samples

ImageFile	Demonstrates all manner of image manipulation using the ImageFile object (shown in illustration)
Minimal	Smallest amount of code necessary (1 line) to select a device, select an image, and transfer it from the device
Widget	An interesting gizmo for exploring item properties and such

Scripting Samples

VideoPreview.htm	Demonstrates using the Video Preview control in a webpage
DeviceList.htm	Enumerates all the cameras connected to your computer and lists their static properties
DeviceList2.htm	Enumerates all the cameras connected to your computer and opens a connection to each and then lists the root item properties
browse.asp	Quick and dirty ASP page that browses the directory tree of images and does interesting things using the ImageFile object's BinaryData property
webcam.asp	Quick and dirty ASP page that displays the current image from a connected webcam
imageinfo.vbs	Demonstrates using an ImageFile object from script
persist.wsf	Demonstrates calling RegisterPersistentEvent and UnregisterPersistentEvent

Instructions for proper installation of the dll and the help files are included in the readme.txt located in the main installation directory. The readme.txt in the samples folder contains the information above. Developers using wiaaut.dll are granted license to freely redistribute the library with their application as detailed in the redist.txt file inside the zip. (Only this dll is listed in this file, so don't overwrite your VB directory's redist.txt with this file!)

This file is provided by VBnet as a service to developers. Any support issues for this product should not be sent to VBnet.
