There is generally two type of 2D graphic, Raster and Vector images. Raster Image is also known as Bitmap image. Bitmap image uses pixels or bits to represent the image structure. Pixels are picture elements that make up the tiny dots on the display screen. The number of pixels or bits will determine the image’s resolutions, the ability of the image to maintain its integrations when image is reduce or enlarge. This is usually express as dpi (dots per inch) or ppi (pixel per inch).
When an image’s pixel or bits is large the integration of the image will be better. However, the bigger the pixel or bids of an image means that image has a bigger file size. One of Bitmap’s weaknesses is that it has difficulty maintaining the link between stripes in the picture when the image is enlarged.
Vector Image is the formulation of digital images with the help of a series of mathematical procedures by recording the relationship between points, straight lines, curved lines, and polygons or other forms contained in the drawing. The recorded vector is then calculated mathematically to calculate the ratio of each line or point linkage contained in the drawing. Ratio recorded by the vector is then used in an effort to enlarge the image so that the relationship between the pixels or bits in the image remains perfectly connected.
Here is a comparison between Bitmap Image and Vector Images:
Vector Engineering was created to overcome the weaknesses of Raster Image (The structure of image that link pixels and bits of an image). One of the practical applications of image vector is to maintain the integration of the image. For example taking company logo and enlarge it to be fit into a website or other media.
