Digital Imaging is..

Digital Imaging- is the creation of digital images typically from a physical object. The term is often assumed to imply or include the processing, compression, storage, printing, and display of such images.

-is a representation of a two-dimensional image using ones and zeros (binary). Depending on whether or not the image resolution is fixed, it may be of vector or raster type. Without qualifications, the term “digital image” usually refers to raster images.

Raster images have a finite set of digital values, called picture elements or pixels. The digital image contains a fixed number of rows and columns of pixels. Pixels are the smallest individual element in an image, holding quantized values that represent the brightness of a given color at any specific point.

Vector images may be created from scratch with illustration software, or by converting a raster image to vector form.

Often, both raster and vector elements will be combined in one image, for example, in the case of a billboard with text (vector) and photographs (raster).

The user can utilize to see the image. The GIF, JPEG and PNG images can be seen simply using of web browser because they are the standard internet image formats. The SVG format is more and more used in the web and and is a standard W3C format.
