Vector images are different from raster images. They are made mainly of paths, that has a mathematical formula. It tells what fills or borders the colour and the path to which it is shaped. Mathematical formulas determine the rendering of a vector image and these images keep their appearance despite size. You can scale them indefinitely and use them to edit in softwares like InkScape, CorelDraw and Illustrator. Vector images are more suitable for solid, simple colours and you can use them for imitating photographs. Vector images consist primarily of shapes that has their distinct colour. That’s why vectors do not have the shading, shadows, and gradients of raster images, rather one has to rasterise a part of that image. Vector graphics that are original are made up of wireframes. Colour fills these wireframes. Since one can scale vectors without losing their quality, it is suitable for embroidery, signage, product artwork, etchings, engravings, illustrations and logos.
Different between vector images and raster images
Vector images have fewer details, but have paths that are more precise. Raster images have more details.
- Vector images are more suitable for drawing, while raster images are more suitable for printing.
Softwares for vector images include InkScape, CorelDraw and Illustrator, while raster softwares include GIMP and Photoshop. The file types for vector images are saved as .pdf, plus.eps, .svg, .cdr and .ai while the file types for raster programs are saved as .pdf, .plus.eps, .psd, .bmp, .tif, .png, .gif and .jpg.
- Vector images consists of small file sizes and large file sizes, but they are compressible.
- It is hard to blend colours of vector images without rasterising them, while raster images are more capable of complex and rich blends.
- Vector images are scalable infinitely, while raster images are limited by dimensions and resolutions.
- Mathematical formulas define paths, in vector images, pixels are used to make raster images.
- You can use vectors for making embroidery, signage, product artwork, etchings, engravings, illustrations and logos. Vector images are more suitable for solid colours and scalable shapes.
- Raster images tend to be larger in size and they come with a dimensional size and higher resolution. They should have all the necessary information for rendering the image like pixel arrangement, colours and pixels. Vector images tend to be lesser in size and they are less compressible when you compare them to raster images. Vectors depend on calculations from programs, which are mainly mathematical calculations. Raster images must maintain their quality through a lower resolution. When you resize vectors, the mathematical equations recalculate to maintain the sharp edges, crisp and vector graphic. Vector images maintain the resolution.
- Raster images can display various colours and involve colour editing.
- Scalability: Vector images are more scalable images than raster images.
- More realistic graphics: However rasterized effects can be added on vectors. Vector images are less efficient for rendering, since raster images have more shadows, gradients, shades, and colour-blends.
Can you combine vector images and raster images in graphic design?
The answer is yes. You can do this. You can use raster images to blend vector images. Nevertheless take note of the quality of vector images when it comes to resizing. Combining raster images with vector images can give it a decent finish.
