Available in an expanded edition, the e-book A Basic Guide to Resizing Digital Images is a practical illustrated guide to resizing (up- and downsizing, enlarging and shrinking) digital images that are stored in bit-map or raster formats, including image formats such as jpeg, gif, tiff and png. It includes step-by-step instructions and the formulas needed to resize digital images to specific requirements. Among the areas covered are color depth; visual acuity; spatial resolution; digital scanning resolution; image resampling techniques; image resizing software applications, and pixels, resolution and image size. A new section discusses how to apply theory to achieve specific resizing goals. Andrew Reid; Imaging Associates International, Gordon, Australia, 2007; $14.95.
- The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
