12/9/2023 0 Comments Vector raster bitmapLike most things in life, it is about using the right tool for right job. So if you scale up a vector graphic it will always appear the same as it is effectively resolution-independent. Vectors on the other hand are effectively lossless and can be scaled infinitely without any loss of resolution, since scaling them is merely a matter of scaling the mathematical formulae that express that image. No additional detail can be obtained from the image since the amount was “fixed” at 400 x 400 pixels when scanned. What will happen is that you reduce the quality of the image because you are now spreading 400 pixels into 800 (2 pixels to every 1), and since each pixel can only contain one single colour, the software has to approximate the colours of the new pixels by averaging it with the colour of each pixel either side. Then you realise that you actually need it to be 800 x 800, and so decide to scale it up in Photoshop or another image editing program. To use vector and raster images properly you need to understand how resolution can affect what you end up with.įor example, let’s say you scan or import an image (raster) that is 400 x 400 pixels wide. This is why input and output resolution is vitally important with raster images in a way that they are not with vectors. If you scale up the scanned image you will gradually see those pixels become more and more apparent, since the number of pixels is set at the moment you scan the image and defined by the image size and DPI (dots per inch) if you are looking to print it afterwards. Scanned photographs are a good example of raster images, as the computer has to break the real photo down into individual pixels of separate colours. Moho Pro animation software is a vector-based animation software, although it can also handle bitmaps Many animation programs now have the ability to work in vectors. They are also used heavily in 2d animation as a particular style that was initially popularised by Flash but has now become ubiquitous. Vector graphics are excellent for the web, architectural design or anything that requires precision of line like technical drawings that can be easily transferred to a machine for moulds or 3d printing etc.īecause they are a mathematical expression it is very easy to use them in manufacturing. The pixels are called “bits”, so it is basically a map of the bits in a raster image. Pixels become more obviousīitmaps are simply another name for raster images. Raster image on left, and scaled up on right.
