As you may have guessed, the more pixels in the image and the higher the resolution is, the higher quality the image will be.įor example, if we scale a raster image to enlarge it, without changing resolution, it will lose quality and look blurry or pixilated. The number of pixels that make up an image as well as how many of those pixels are displayed per inch, both determine the quality of an image. Since raster images are pixel based, they are resolution dependent. Raster images are compiled using pixels, or tiny dots, containing unique color and tonal information that come together to create the image. These are the types of images that are produced when scanning or photographing an object. Some examples of bitmap files are GIF, JPEG, PNG, TIFF, XBM, etc.Raster (or bitmap) images are generally what you think about when thinking of images. This is why brands convert raster logos to vectors while putting them on business cards. Also, if you reduce the image size, they lose quality. Once they are zoomed in, they may appear grainy or blocky. The more the number of bits, the greater the image’s resolutionīitmaps contain huge information that builds excellent-looking pictures but is unsuitable for scaling. Each pixel in this bitmap will have numbers like 18, 22, and 40 as bits of information. When bitmap displays a complex image, for instance, there are various shades and gradations in lighting and colors in the scenery. So, the display of the pixel is black or white, which is 1 or 0. Consider a single letter on this page every pixel of that letter will have only one bit. Each alphabet on this page is made of several pixels. Let’s take an example of a white page with black letters. In a bitmap image, each pixel has a bit that indicates what shade it should reflect, and it could be the background of the image, foreground, or something different. When a bitmap file displays on the computer, the system reads it and determines what color to use for each pixel. This file is a map of bits that forms images when delivered to a display screen. It is a format used to store files in a computerized form. Therefore, organizations use logo vector converters to turn their logos into this format.Ī bitmap is a raster file that contains colorful blocks. You can also reduce them to print on the tiniest accessories. You can use vector files blown up on a billboard without damaging any part of the logo or graphic. They are easily editable, and you can modify individual elements without hurting the files’ other objects. The vector files are small-sized and do not contain pixel information, only mathematical points. To open this file, you can use Adobe reader, EPS viewer, and CoralDraw. It doesn’t support transparency, unlike the newer files. Encapsulated PostScript or eps: Older vector files.Scalable vector graphics or SVG: Helpful for the web, where it can be searched, classified, and scripted.Portable document format or pdf: Helps exchanging documents across platforms and can be edited on Adobe Acrobat.Adobe Illustrator or ai: Widely used for company logos and other print media and digital graphics.Examples of some of the standard vector files are: Vector conversion makes them easy to print in high resolution. Vector files are an excellent format for company logos, poster designs, business cards, etc. Hence it cannot be used for real-life photos. Although the vector image is scalable and does not break, it has a less realistic display. They are 2D images that are formed from a combination of individual objects containing points, lines, and colors. Because of this, quality vector files are used to create high-quality artwork that can be resized to any scale. This type of file can adjust in size without losing its resolution, making them easier to edit. They are created using advanced formulae to establish grid points.
