![]() ![]() Whenever you use the brush tool to create a digital illustration, every brush stroke adds pixels along the brush path-the number of pixels dependent on the size of the Photoshop document and the radius of the brush you are using. Although the pixel grid is not visible, designers add to it when creating graphics in a raster program like Photoshop. Think of a raster like a mosaic: from up close it just looks like a series of squares, but from further away an image forms. A pixel is a square of solid color made from the combination of red, green and blue light (also known as subpixels). Raster images What is a raster image?Ī raster image is any digital graphic that is made out of pixels arranged on a static grid. Drawtify is an online graphic design software with vector drawing, layout, photo editing, and typography. vector images and help you decide which format fits your project.ĭrawtify, make design easier. We’ll look at the nuances between raster vs. The answer really lies in what you are creating. Both raster and vector images have their own advantages and downfalls depending on the project at hand. It’s important to understand the fine differences between them and when to work with each-no matter if you’re a new designer, a seasoned pro, or a marketer looking to hire a designer. If your project requires scalable shapes and solid colors, vector is the best choice, but if your project requires complex color blends, raster is the preferred format.What’s the difference between vector and raster images? Vector and raster images differ in their resolution, the amount of detail they contain, and where they are used. Raster images are best for digital photos and print materials. Their native files are needed for coin designs, laser engraving, t-shirts, patches, etc. They're also used in lower thirds for videos, web-based objects and rendering 2D or 3D computer animation. Raster-based software (e.g., Adobe Photoshop)Ī vector graphic's small file size and scalability make it uniquely suitable for use in digital printing from business cards to billboards.Vector-based software (e.g., Adobe Illustrator).Digital printing (e.g., business cards, billboards).However, a high resolution image printed at a small size will cause the pixels to "cram" together and will make the image look as unprofessional as not having enough pixels in a large image. Resolution limits the size the image can be scaled up without being able to see pixels. The lower the number of pixels, the lower the resolution. ![]() More pixels result in better quality at the same or larger sizes as the original, but this also increases the size of the file and the amount of space it takes to store the file. Each image can only contain a fixed number of pixels the amount of pixels determines the quality of the image. These images are created by digital cameras, by scanning images into a computer or with raster-based software. Pixels appear like little squares on graph paper when the image is zoomed in or enlarged. Raster images are made of pixels or tiny dots that use color and tone to produce the image. Because they consist of lines and anchor points, the size of the file is relatively small. These graphics are also device-independent, which means their quality doesn't depend on the number of dots available on a printer or the number of pixels on a screen. Their lines are sharp, without any loss in quality or detail, no matter what their size. Because these graphics are not based on pixels, they are known as resolution independent, which makes them infinitely scalable. These graphics consist of anchored dots and are connected by lines and curves, similar to the connect-the-dot activities you may have done as a kid. Vector graphics are also known as scalable vector graphics (SVG).
