When scaling up, Genuine Fractals exploits the self-similarity of an image to increase its size while preserving detail. In 1997, Genuine Fractals won a MacWorld Eddy. [5] It is also notable because Genuine Fractals was the first product developed on PC and ported to Mac to win an EDDY.
The resulting image is larger than the original, and preserves all the original detail, but has (possibly undesirable) jaggedness. The diagonal lines of the "W", for example, now show the "stairway" shape characteristic of nearest-neighbor interpolation. Other scaling methods below are better at preserving smooth contours in the image.
Within an image link, the options are as follows: thumb – displays the image as a framed thumbnail at the user's default size; frameless – displays the image as an unframed at the user's default size; upright – scales the image to approximately 75% of the user's default size (25% smaller)
The software mainly consists of a number of command-line interface utilities for manipulating images. ImageMagick does not have a robust graphical user interface to edit images as do Adobe Photoshop and GIMP, but does include – for Unix-like operating systems – a basic native X Window GUI (called IMDisplay) for rendering and manipulating images and API libraries for many programming languages.
An image scaled with nearest-neighbor scaling (left) and 2×SaI scaling (right) In computer graphics and digital imaging, image scaling refers to the resizing of a digital image. In video technology, the magnification of digital material is known as upscaling or resolution enhancement.
Many applications on Mac OS X use either the Core Image or QuickTime APIs for image support. This enables reading and writing to a variety of formats, including JPEG , JPEG 2000 , Apple Icon Image format , TIFF , PNG , PDF , BMP and more.
