Topic > Comparing Raster (Bitmap) Graphics and Vector Graphics - 1431

Introduction: I decided to compare raster (bitmap) and vector graphics and their uses in modern digital multimedia content. I'll start by defining what they both mean. So take a brief look at how they were first used. Provide examples of their pros and cons, their current uses, and give my opinion on which I think is the best option and why. Raster (bitmap) graphics definition: “A raster graphic is a digital image composed of an array of dots. When viewed at 100%, each dot corresponds to a single pixel on a display. In a standard bitmap image, a each dot can be assigned a different color. Together, these dots can be used to represent any type of rectangular image. There are several bitmap file formats. The standard uncompressed bitmap format is also known as "BMP" format or DIB (Device Independent Bitmap). Includes a header, which defines the size of the image and the number of colors the image can contain, and a list of pixels with the corresponding colors. This simple and universal image format can be recognized on almost all platforms, but it is not very efficient, especially for large images.” (techterms, 2014) Textbox: Figure 1 To reduce the file size in other bitmap image formats, e.g. GIF, PNG and JPEG incorporate compressed algorithms. The type of compression used varies depending on the format, but they all represent an image as a grid of pixels. Uncompressed BMP files are significantly larger than compressed bitmaps, so they take longer to download. That's why most images you see on the web are compressed bitmaps. Regardless of the file format, the image will appear blurry when enlarged because each dot will take up more than one pixel. Common raster formats include: BMP ...... half sheet ...... and can be generated via server-side or client-side scripting languages. SVG (SVG Tiny version) is the mobile version of SVG. These images can not only take advantage of anti-aliasing, but can count links and be displayed as wallpaper. Conclusion: In conclusion, designers must choose how to express their creativity using vector or raster graphics. By understanding the differences between graphic types, their strengths, and their limitations, you can achieve the best results. Ultimately, it depends on what graphic/image you want to create and what you intend to use it for, this will determine which type you choose. For photorealistic images, raster is the solution. If you need to scale and manipulate graphics and download speed is important to you, then you should consider the vector-based format. Luckily we can have both!
