We can divide digital graphics into two categories: raster and vector graphics. If you are in confusion about these two graphics, then you must read this article because today we are going to talk about these two.
Today, in this article we are going to focus on some of the points given below:
– What is Raster (bitmap) Image?
– What is vector image?
– What is the difference between Raster and Vector Graphics?
– When to use Raster and Vector?
Please read this article to get complete information about raster and vector graphics.
What is Raster Image?
Raster image or bitmap image are made up of several smaller squares or dots that we call pixels. If you zoom this image then you will be able to see these small pixels.
Photos taken with your mobile phone camera are examples of raster image too.
This type of images is based on pixel and the resolution. Their resolution is determined by DPI (Dots Per Inch) or PPI (Points Per Inch).
Due to being pixel-based, when their size is enlarged, after a limit they become blurred or pixelated and their quality gets worse.
In the Raster image, you can easily create a smooth painting by mixing several different colors.
To create or edit Raster image, you need software like Photoshop, GIMP.
Images saved in formats like JPEG, PNG, GIF are also raster images.
What is Vector Graphics?
A vector image is not based on pixels. Their resolutions are independent. Vector graphics are based on mathematical calculations.
The size of this type of image can be done as little or as much as we want, and in doing so, the image quality will not be affected.
That means without losing quality, we can print such images in any size and this is the biggest advantage of vector graphics.
Vector graphics are perfect for drawing, you can do this type of drawings from Adobe Illustrator or Corel Draw.
Difference between Raster and Vector Graphics
The difference amongst vector and raster illustrations is that raster designs are made up of pixels, while vector designs are made up of paths. Examples of raster graphics are a gif or jpeg, There are a variety of pixels of different hues, which together shape a picture. Similarly examples of vector realistic are an .eps record or Adobe Illustrator? the document is made up of paths, or lines, that are either straight or bent.
The information files for a vector image contains the focuses where the path begins and ends, how much the paths bend, and the colors that either outskirt or fill the paths. Since vector designs are not made of pixels, the pictures can be scaled to be huge without losing quality. Raster illustrations, then again, progress toward becoming “blocky,” since every pixel increments in the estimate as the picture is made bigger. This is the reason logos and different plans are commonly made in vector design – the quality will appear to be identical on a business card as it will on a board.
When to use Raster and Vector?
Now perhaps you might have been asking this question in your mind what is better than these two graphics formats and which of these formats should we use?
The truth is that both the formats have their own advantages and disadvantages and they are used for different purposes.
Which format of raster and vector should you use, it depends on what type of image/graphic design you are designing.
When to use the Raster Image?
Use raster graphics for the digital image, photography.
– Most of the images available on the Internet are in JPEG, GIF and PNG format, which are the raster image.
– It is used in web design. The images for the website are better than the raster format for images design.
– If you are adding the gradient, blur, texture, shadow effects in the picture then use raster.
When to use vector image?
Use vector when you have a large size of a design such as banner, poster etc.
– The vector image is used in logo design so that when needed, the logo can be scaled to any size.
– You can use this format to create the illustrations.
– The vector is also used in CAD, engineering design, 3D modeling etc.
