Acquiring images from WIA devices
Windows Image Acquisition (WIA) devices are digital scanners and cameras
that support the plug-and-play technology found in newer versions of Windows
operating systems.
To acquire images from WIA devices, click Open and select the drive that
corresponds to the scanner, camera, or any other imaging device that is plugged
into your PC. You can then select the file you want to open.
Note: PhotoImpact supports EXIF image data contained in most WIA-based images.
For more information on using and exporting EXIF information, please refer to
the PhotoImpact Album Manual.
Viewing images
When you open an image in PhotoImpact, the pixels of the image are "mapped"
onto your screen pixels. Controlling the mapping of these pixels determines the
way you see the images. For example, displaying an image in actual view (100%)
maps one image pixel to one screen pixel. PhotoImpact offers you several tools to
let you view your image as needed.
