This makes vector graphics perfect for creating logos, illustrations, and other images with simple forms and solid colours. These properties are saved as mathematical equations that can be changed and manipulated without changing the image's quality. Vector graphics, as opposed to raster graphics, are resolution-independent, which means they may be scaled up or down without losing quality.Įach vector object is described by geometric properties such as position, direction, and magnitude. Vector graphics are digital images made up of mathematical equations defining lines, curves, and forms. Raster graphics are perfect for capturing photographic pictures, but when scaled up or printed at a large size, they might become pixelated or indistinct. Raster graphics are digital images made up of a grid of pixels, each with its own colour value. Raster images, on the other hand, might become pixelated or unclear when stretched beyond their initial size, limiting their scalability. This is due to the fact that raster images can capture subtle changes in colour and tone that vector graphics cannot. Raster graphics are frequently used for pictures and other detailed visuals with numerous colour variations. In addition, raster graphics might have huge file sizes, making them unsuitable for web-based applications or other cases where file size is a problem. Because they are made up of a set number of pixels, they might become pixelated or unclear when scaled up or printed at a large size. However, raster graphics have several limitations. Raster graphics are also easily shared and edited because they are widely supported by digital devices and software applications. Raster graphics have the advantage of being able to capture the minute details of photographic images, such as differences in colour, texture, and shading. Raster graphics are suitable for images and other detailed images with a wide range of colours. The higher the resolution, the more detailed the image, but the larger the file size. The resolution of a raster image, which is the number of pixels per inch (ppi) or dots per inch (dpi), is used to determine its quality. What is Raster?Ī raster image is made up of small, coloured squares known as pixels. Read this article to find out more about Raster and Vector and how they are different from each other. Raster graphics are made up of pixels and are best suited for images and complicated images, whereas vector graphics are made of mathematical objects and are best suited for simple shapes and solid colours. For example if you combine sweet wrapper and stencil you can apply the orange tint effect only to the area through the mask.Īdjustment layers and masks are not saved as part of a raster file, but are part of the drawing packages custom format file, so that you can change it when you load it back in.Raster and vector are two methods for creating digital images. You can combine your stencil cutout (mask) and sweet wrapper (adjustment layer - or just 'layer') together if you wish. Well the piece of paper is basically a mask. Mask: imagine cutting out a shape from the middle of a piece of paper and laying the sheet with the hole over the top of your picture and painting over it so that you end up really only painting over the bit that you can see through the hole. You can get all sorts of different special effects. If you scrunch up your sweet wrapper you might get a crinkly effect as well. Imagine holding an orange trnsparent sweet wrapper over your image and looking through it - you get an orange tint to your picture - the sweet wrapper is an adjustment layer. You get vector files with Illustrator and Inkscape.ĭrawing packages that save in a vector format remember all the information about the type of brush so that you can change the colour or thickness of a brush stroke next time you load/edit it.Īdjustment layer: applies a special effect to your image. Vector: the image is made up of brush strokes and fills, and that information is retained so that no matter how much you scale the image up and down, the image is drawn with the appropriate size brush and you don't suffer from loss of quality. Typically raster is the type of format you save as when you've finished your drawing and want to use it in software or on the web. You get raster files with paint packages like and Photoshop.ĭrawing packages that use brush tools to draw with, but save in a raster format (gif, png, jpeg) immediately lose all the information about the type of brush, so typically to edit it again you need to change each little square of colour, or draw over it - or start again Raster: the image is made up of tiny coloured squares which map to individual pixels on the screen when the image is displayed at a scale of 1:1 but if you scale it up to look bigger then it gets blurry.
