And being able to precisely control the color of each and every one of those pixels in a wide variety of ways is what makes Photoshop such a uniquely powerful tool. Now photographs are great examples of raster-based images because there are lots of very fine gradations between one region of an image and another. Which means it's primarily designed so that you can manipulate each and every one of these individual pixels that make up your image. Now Photoshop is primarily a raster-based image editor. If you zoom way in to a raster image, using command or control plus several times, eventually you'll get down to a grid of squares that shows the individual blocks of color or pixels that make up the image. Now raster images are defined pixel by pixel. Let's take a brief moment and talk about what these are and why you need to know about them for teaching and learning. Selecting a region changes the language and/or content on .- You've likely heard the terms raster and vector images. All three offer their own specific advantages, disadvantages and ultimately, use cases. Raster images are used for non-line work art, like photography. Theres no need to switch to Photoshop, grapple with the vector tool, or wrestle with Boolean operations. Vector graphics are primarily used for illustrative elements, iconography and logo design. Basically, vectors don’t lose quality when resized.Īt the same time, don’t confuse either raster or vector formats with RAW files, which are unaltered, uncompressed images made up of direct data taken from a camera’s sensors. Trimming Raster Images You can trim both raster and vector images. They’re created with mathematical equations, lines, and curves - using points fixed on a grid - which means images can be made infinitely larger (or smaller) without losing resolution. This means raster files can become distorted if you resize them beyond the amount of space the pixels were meant to fill. Raster files are composed of a fixed number of square pixels. These vector points, basically allow your computer to play Connect the Dots. In a vector-based program, the same square would be made of only four dots, one on each corner. In a raster-based image creation program, a square would be made of thousands of pixel dots. It merely creates raster files with embedded vector data. A vector-based program does not render images on a pixel-by-pixel basis. But, you can open and edit vector files in Photoshop either as a smart object or rasterised file. One of the primary uses of Photoshop is with digital photos, which are usually raster files. Photoshop does not now, and never has created real vector files. Is Photoshop vector-based No, Adobe Photoshop is a raster-based programme, meaning it uses pixels to create detailed images. There is a previous question about it here Cai at 18:41 The short answer is you can't use Photoshop. Illustrator is only needed to tweak lines, knockout holes and add stylized text. Best vector results will come from high resolution scans into Photoshop and then Streamlined. As a result, raster graphics will distort or lose sharpness if they are enlarged. All of my cartoons start out as hand drawn sketches and are turned into vector art using Adobe Streamline. Raster files consist of tiny pixels and have a set size and resolution. They’re formed in different ways and are better suited to some projects than others. But possibly some some simple SVGs if you are using CC. There are two basic file types: raster (or bitmap) and vector. Thus, while native Photoshop file images can be incredibly vibrant, they are not vectors. To create a vector image, use a vector-based program, such as Adobe Illustrator or CorelDRAW. Technically speaking, Photoshop files cannot be considered vector images because the native formatting for Photoshop files is raster, meaning that they are comprised of tiny building blocks known as pixels. However, raster images are readily available in a variety of file formats, making them more accessible and shareable than vectors. When you work on any digital project, you’ll encounter two distinct types of image files - raster and vector. Generally, vector image files take up less space, while raster files are larger. Let’s take a step back before actually defining the vector file.
