Basics of Images
Essentially there are two types of computer
graphics namely Vector graphics
and Bitmap graphics.
Vector Graphics
Vector graphics are resolution independent,
it gets its form through parametric equations, consisting of
an outline and a fill and must eventually be displayed as a
bitmap. The image shows a Vector graphic.
Bitmap Graphics
Bitmap graphics are a quilt of pixels
that make up recognizable images. These are also called asRaster graphics.
The Picture Element
Placeholder (PIXEL)
The pixel
short for Picture element is the smallest whole unit of bitmap
graphics.
A pixel has two distinguishing characteristics. First it has
a position relative to that of the other pixels in a bitmap
image. The second characteristic is that Pixels have the color
capability to measure in bits. A pixel's place in a bitmap image
enumerates the resolution of an image. This fractional amount
is usually expressed as pixels per
inch (ppi). The resolution actually
tells us the number of pixels that are present in an inch.
