Image is a main key to impress the audience or visitors on websites, magazines, brochure, templates, newspaper, infographics and many more showing effective content with the eye-catching images. In the world of images every organization wants best image quality services for their online store or website. Every business knows image quality is must for its store or website. Therefore, every company wants that their images are well edited by an image editing service provider. Raster and vector are two of the most widely used image techniques.

Raster and vector are the techniques which are highly demanded in today’s world because nowadays, there are so many companies who are continuously working with many Image editing service providers. That’s why image editing industry is growing rapidly. Raster and Vector are two types of image files. Raster images are widely used in the web and its images are pixels based images. Vector is a common technique for graphics in which the images doesn't lose its quality even when users zoom the image. Both the images are basically used for logos, 3D effecting images and technical illustrations. Raster technique is primarily used in Photoshop and Vector technique used in Illustrator and CorelDRAW. It depends on the user how to use the Raster and Vector image.

Here, we talk about two great techniques of editing, the first is raster or another is vector. The difference between both the techniques are:-

Raster image is full of dots or pixels based image. Rasterized image is commonly use in 3D programs or web pages. The most popular formats of raster images are jpg, gif, and png format. If you’ll zoom a raster image the quality of image will decrease continuously.

Vector Image is little bit opposite to Raster because it is actually not proper dot based or pixel based image. It’s a sharp image that can be expanded without affecting the quality. The quality of image is not affecting in case while you zoom or pixelate any vector image. The Vector image is also used for 3D programs.

Raster and Vector - Uses of them

Raster and vector programs are two of the finest images editing technique in the world. The common or important example of raster is digital photographs. Images of raster are all based on bitmaps and that of vectors is based on path. Each and every pixel represents a different a color or image pattern and then thousands of pixels arranged in actual pattern; those pixels display an image on computer screen. It’s generally used in Photoshop or Illustrator like image editing software. This technique is mostly used in useless images to recreating in new nature. Raster images are generally used with photos therefore Photoshop is a photo editing software. Raster images are always preferable when we working with images or photographs.

Raster or pixel-based images are better than vector programs because they can use a plentiful number of different colors in every pixel. By arranging pixels and slowly incrementing or changing the color or shade of the pixels adjacent to them, vector creates a fine gradation from one color to another.

The number of pixels that make up raster images varies mostly depending on the intentional use. Some small graphics used on websites to represent elements such as buttons might be 25 × 25 pixels. This measurement is considered the file’s resolution. Extra resolution files are generally required for printing, while lower resolution files are normally for screen display. The resolution of a raster image is directly related to its file-size, more pixels equal and more. Raster or vector technique is basically a classic image editing technique that helps a lot to your imagination is on the paper actually. Raster or vector images are having really effective while you present a presentation.

Here are few uses and advantages of raster or vector image techniques:-

  • The raster images generally come in JPG, GIF and PNG formats.
  • The vector images generally come in SVG, EPS, AI and DXE formats.
  • Vector images are mostly used for logos, brochure, newspaper and other printed material.
  • An Advantage of using vector images is file-size efficiency.
  • A vector image always looks smooth, no matter how close you zoom in. Even how much you increase font size, the size of font and the image never pixelates.
  • If you are creating a logo or illustration, in that case vector images are the best.
  • Many of organizations create all of their insignia or logos as vector images.
  • Keeping a good library of vectors image can save your time because of the ability to re-size on the fly.
  • Raster images are officially accepted for digital publication but it doesn’t work well in printed objects.
  • Raster images are generally used for all graphics that has to be published digitally.
 

Whether to go for raster or vector images

In the world of images every organization wants best image quality for its online store or website. A raster image is pixels based image while vector images are path based. A raster graphic, such as a GIF, PNG and JPEG format, basically is an array of many pixels in several colors, which together form an image. A raster is image made with many of pixels, each a different color, arranged to display a picture. A vector image is made up with paths; each with a mathematical formula that is tells the path how it is shaped and what color it’s bordered with or filled by.

The big difference is that raster image pixels do not maintain their appearance as image size increases - when you blow a photograph up, it becomes blurry. Vector images retain appearance regardless of size. Some vector programs do have the ability to make color gradients within one single shape, but it’s actually raster effects. A vector graphic with gradients color contains vector and raster component and won't be suitable for process that requires 100% vector or true vector art.

Many images can be made with both raster and vector techniques and look exactly the same on both programs. Images with a subtle gradation of one color to another color are the images that will look really different since vector programs need to create a different shape for each shade of color. Terms “raster” and “vector” are normally used as antonyms to each other. Photographs are raster images and probably the best example of images completely made of color blends - or shade blends in case of black & white images - and those images look different when drawn in vector format.
