Developed as a XP alternative to the Wang/Kodak controls for Windows XP. The Microsoft download page for this dll states the "Supported Operating Systems" is Windows XP, and that "Windows Image Acquisition Automation Library v2.0 is only supported on Windows XP with Service Pack 1 installed." The dll relies on GDI+ available under Windows XP. I have also received reports the dll can also be used on Windows 2000 systems, though possibly only those with the latest service packs. Please see the Comments below. |

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): Prg.rarHis heart skipped a beat. He didn't have any streaming software open. He tried to Alt+F4, but the screen stayed locked. He pulled his hand back, staring at the green indicator light on his monitor bezel. One Tuesday at 3:00 AM, he stumbled upon a directory on a Romanian server that hadn't been modified since 2004. Amidst the sea of broken links and corrupt files sat a single, massive archive: . PRG.rar Leo panicked and reached for the power cable of his desktop, ripping it from the wall. The monitor killed over instantly. He sat in the dark, breathing heavily, the green afterimage of the glowing eyes burned into his retinas. His heart skipped a beat On the game screen, the NPCs began to shift. Their tiny, 16-bit faces distorted, stretching out into horrifyingly detailed, photorealistic renders of human eyes. He pulled his hand back, staring at the When he looked up into the mirror, his blood turned to ice. Taped to his actual, physical bathroom mirror was a small, crudely cut piece of paper with pixelated font that hadn't been there ten minutes ago: Level 2. The file took an agonizing hour to download over his high-speed connection, which was strange for its listed size of just 500 MB. When he tried to extract it using WinRAR, his processor spiked to 100% capacity. The files that poured out into the folder were bizarre: Thousands of .dat files with strings of gibberish names. A single executable simply named Run.exe . A text file named READ_ME_NOW.txt . 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. Download Microsoft Windows Image Acquisition Library v2.0 (520k) |

| If the file 'gdiplus.dll' is installed on a Windows 2000 machine but not properly registered, calls to wiaaut.dll (the imaging dll) will not work. After registering gdiplus.dll calls to wiaaut should succeed. |
