Vector graphics, also known as raster graphics or raster images, are created by compressing data in the form of a repeating pattern. This type of image is easy to handle and manipulate. Vector illustrations can be used for everything from wireframes to full-scale productions. If you're planning to start using vector graphics, you will need to learn a bit more about them before you can begin to create your own works of art. Here are some basics about vector graphics that you might want to know before you get started.
The words" Vector" and "graphic" go hand in hand. A vector illustration is created by using lines to represent physical properties of an object. These lines are made to appear as thin or fine lines on a computer screen, and they may be expressed as curves, lines, or textured marks. The actual image that you see on the computer screen is often created by combining a bitmap, which is the representation of an image through multiplexing, with a vector image. In computer terms, the term "bitmap" is usually used to describe vector illustrations.
Vector graphics are generally better suited for traditional computer-art techniques, such as layering or illumination. However, it's not impossible to implement vector graphics in a non-traditional media, such as Flash. In fact, Flash already includes a basic implementation of vector graphics. If your project's include complex visual elements such as detailed terrain or moving objects, it's recommended that you use vector graphics wherever possible. You'll be glad you did once the finished image looks exactly how you imagined it.
Vector illustrations can have two representation formats: raster and vector. The difference between the two is slight. Vector graphics use large channels to represent individual pixels. On the other hand, raster graphics use rows and columns of pixels to represent an image. Raster graphics tend to be more flexible because you can use any number of different size channels.
Vector images tend to load faster on some computers than raster graphics. This is because vector images have fewer overhead functions such as clipping planes and constant resizing. This makes them ideal for mobile devices, such as touch screens. However, if your images are too large to fit into a small screen, they will look stretched. You can compensate for this by cropping the image. If you're not sure about how to do a job yourself, hiring a professional graphic designer is an option.
The main advantage of vector graphics is flexibility. They are open sources, so you can modify the code to alter the appearance or size of the image. For example, you can create an image with a certain width and height and change its shape and dimension. This can be useful if you need to create different types of graphics, but don't want to modify the source file. Vector graphics are also often used in combination with raster graphics.
In addition to their flexibility, vector graphics allow you to use more colors and textures. This makes it easy to add a lot of visual variety to your images. On the downside, vector graphics can cost more to create, but if your images are going to be used on the web, it makes up for the higher initial costs.
The best way to learn more about vector graphics is to simply look at a lot of existing images. You'll quickly get a feel for what looks good and what doesn't. Look at a huge variety of sizes, shapes, and colors and decide what you like. Then try out various styles of your own to see what works and what doesn't.
