Raster vs Vector

Project Two

Pixel Graphics & Object Graphics

Create a digital diptych exploring concepts of raster
and vector imagery and text.

This first design project explores some of the major topics presented in our past reading on ‘digital  images.’  This visual exercise will begin to deal with concepts of high/low resolution (pixel graphics), greyscale, bitmap, ppi/dpi, editable type (vector based object graphics), type as image, CMYK, line art, color modes, tiff images and file types used for digital production.

Content (text) for this project must use language associated with topical concepts discussed from reading. All imagery must be self-generated and produced accordingly. You may use any digital camera at your immediate availability; this can include your phone, DSLR, or digital camera. Image content does not have to fully represent/mimic
editorial content.

Project Two: Raster vs Vector

Raster
In computer graphics, a raster graphics image is a dot matrix data structure, representing a generally rectangular grid of pixels, or points of color, viewable via a monitor, paper, or other display medium. Raster images are stored in image files with varying formats.[self-published source?]

A bitmap, a single-bit raster, corresponds bit-for-bit with an image displayed on a screen, generally in the same format used for storage in the display’s video memory, or maybe as a device-independent bitmap. A raster is technically characterized by the width and height of the image in pixels and by the number of bits per pixel (or color depth, which determines the number of colors it can represent).

The printing and prepress industries know raster graphics as contones (from “continuous tones”). The opposite to contones is “line work”, usually implemented as vector graphics in digital systems.

Vector
Vector graphics is the use of polygons to represent images in computer graphics. Vector graphics are based on vectors, which lead through locations called control points or nodes. Each of these points has a definite position on the x and y axes of the work plane and determines the direction of the path; further, each path may be assigned various attributes, including such values as stroke color, shape, curve, thickness, and fill.
