We know about raster images and their structure from the above discussion, now we would know about the vector image.
Vector graphics is the opposite form of raster graphics.
Your image must be at least 1500 pixels wide. If a printer requires a minimum of 300 dpi and you want to print an image in an area that is 5 inches wide, multiply 300pixels × 5 inches = 1500.

How to determine the best printing size for your raster image? Raster image comes with different file types like, Although, images with high resolution should only be used in the device that has the ability to display them. So, the size of the raster image has been always in a fixed value. The higher the resolution is the greater the number of pixels that have been contributed to form that. Resolution is nothing but millions of square pixels. Raster image comes and is displayed with a specific resolution. Then the image should be at least 2550 pixels in width and 3300 pixels tall with a resolution of 300 PPI.Ībove all, raster images can’t be scaled in a larger size and if they are scaled, it loses quality and becomes blurry because the entire pixels become larger but they can be scaled down. Imagine that you are going to print a brochure that needs a background image including a size of 8.5” ×11” inch. When you are detecting resolution in any output device, what do you think is that the files own eternal specifications? No, it’s not, it is the output capacity of the device. The pixel resolution is required by a particular printer.A printed raster image quality depends on 2 major things, We know that the quality of raster images depends on PPI (pixel per inch). Raster the program uses adobe photoshop and GIMP and one can use this program in designing websites, apps, icons, banner advertisements, and other purposes. Raster graphics are highly used for photographs, scanned artwork, or detailed graphics. Humans won't be able to notice pixels while you can see them by zooming in a picture on the screen.Ĭhanging the size of a raster image is something shrinking or stretching the pixels themselves. The higher the dpi, the better the resolution. Resolutions of raster images are measured on the scale of dpi (dots per inch). do you want to realize ever what is that resolution? Resolutions are also pixels and pixels are a set grid of dots, so when we say high-resolution images that means, the image contains a greater number of pixels per unit.įor example, an image with 500×700 px means that the picture contains 500 pixels vertically and 700 pixels horizontally. You might be familiar with the word resolution, high resolution, etc. You can find a raster image with so many pixels square (like a mosaic) and they are arranged to create raster images. Raster graphics also known as bitmaps is a grid of individual pixels of color. Ok, I am describing all about raster to vector graphics in detail, let’s look into it, What is a raster image? Unlike the raster program, when you are using a vector program, it will result in you drawing the outline of shapes, which means the vector program works with lines and shapes. When you are using a raster program, it results in dipping a brush in paint and painting. Raster programs are something like painting and vector programs are like illustrator drawing. What is the definition of raster and vector images? I think you have seen artwork both in paint and illustrator. So, they are two simple but complex forms used in computer graphics. Raster image and vector image are two different types of image files in graphic design.
