The term pixel and vector must have been familiar in the ears titodesainer. However, if titodesainer understand what the basic difference between the two?
titodesain.com presents in-depth review of the differences in pixel and vector.
titodesain sure, titodesainer be familiar with the term pixel and vector. Yes, as the basis of nearly all common image formats in use today, pixel and vector are two main categories of 2-dimensional image file modern. However, if titodesainer know, what exactly is meant by pixel, and what exactly is a vector? Then, if titodesainer also know what the basic difference between the two?
Perhaps the difference between the pixel and vector looks very obvious on the surface, but to explain the fundamental differences between them and the main, need pendetilan quite long and complicated. But, take it easy. Not titodesain name if it does not present a complete and accurate information for all titodesainer. So, consider the continued review will also lift the history of computing and graphics technology. (Translated from this site).
Pixel and Raster Images
The term pixel is actually a combination of the word image (picture) and elements (element). This unit is actually not much different from that formulated by Russell Kirsch for the first digital image, more than 50 years ago. Pixel – at least pixel in digital art files – developed for the creation of re-photography.
The idea was to change the format of photo prints by using a grid-based system which consists of color and pattern. “Picture element” is like building a puzzle units and parcel of all digital artwork, whether simple or complex. The first images generated Kirsch is a simple image 176 pixels wide, in black and white, which displays as a toddler boy photo subject. (Photo by the original size shown above).
Raster is a term used for all the images that can be incorporated into the model, and rasterization is the process of converting all of the images that do not have a unit pixel to pixel-based digital images.
Pixel and Monitor
It is important to understand that, when we talk about the pixel graphic files, we do not directly talk about the units of the same pixel, translated by our screen. Indeed, existing pixel before Kirsch and computer scientists who worked with him finally succeeded in creating a digital representation.
Indeed, the pixels on our screen is a set of points of light are red, green and blue, combined with certain brightness level to generate the RGB color model. Because the screen already there rather than the image we see in them, it may be concluded that the pixel monitors are actually already there rather than a digital representation.
However, because the monitor is based on the original models, including RGB color model based on the above statement can be confusing. Well, to simplify, titodesainer quite remember it this way: we use the same word to describe the points of light on our monitors and most basic unit of raster imaging. When we compare the pixel and vector graphics, we will only discuss the pixel raster graphics, and instead of pixels displayed by our screen.
Vector Graphics and the Customizable size
Vector drawing program called Sketchpad the first, created in 1960 by Ivan Sutherland, just a few years later from when Kirsch created the first digital representation. Sketchpad allows users to draw points and lines directly on the screen using the stylus. Although the features that are embedded in Sketchpad at the time were nothing compared with the features possessed by modern vector drawing software, but this application staying digadang as major influencers for applications CAD (Computer Aided Drafting) created next.
While the pixel is the “boxes” of an image, which simulates the points on the screen you, vector is a combination of points, lines, and polygons in the curved algebraic grid. Point, line, arc and a simple polygon is called “primitive”, and became the basic building boxes from a vector art.
The main difference between pixels and vector is a vector is the mathematical space, while the pixels are in a more literal. Pixels are all the same size, and has a position that is clearly defined from the beginning. Meanwhile, the primitive vectors, which are merely points on a grid in a mathematical space does not have a similar restriction. This is why, if you zoom in on and on until it reaches a primitive point of a vector image, you will realize that you might not reach a sufficient depth “deep”.
The conclusion is that, vector drawing does not depend on the image resolution. In contrast, raster images often look worse when you are at low resolution, or when describing an image with a limited number of pixels. On the other hand, vector art can be enlarged and “withdrawn” without any loss of quality.
So, What Every Purpose?
Typography, especially, is very fitting to use vector graphics. Abstract geometric formations very easily clarified with the boundary line of “clean” and arches primitive vector. And, because it can be changed in size from very small to very-very-very large, all the alphabet can be stored as files are very small, and is used to measure anything.
Line art are also suitable for vector programs such as Flash. Many artists prefer to create their artwork in the form of vector, with the goal of creating lines neat and clear, as shown in the drawings of John Krisfalusi, published on his blog-themed animation.
Vector also become a popular format for many types of automotive advertising. Pictures of the car in vector format has become the general rule, though some form of modern advertising does not use it, because the lines are sharp and the clarity that results from vector art can still be maintained, although the size of a billboard. Meanwhile, photography using megapixel super big on advertising billboards considered ineffective because it will result in very large files.
However, the pixel is created for the needs of photography, and is still the best model for photographs and other images that resemble photographs, such as digital painting. Photography deep space satellites such as the Hubble telescope or spacecraft such as Voyager 1 will be produced impossible if only rely photos with the film medium.
