Vector and Pixel: Whats the difference? The key difference between pixel and vector based graphics is how the image is structured. Pixel based graphics are made up from lots of tiny physical squares (or 'pixels') where as vector graphics are mapped out using mathematical equations which calculate where the edges of the shapes sit in relation to one another.
Vector animation is a term used to refer to animation in which the art or motion is controlled by vectors rather than pixels. Vector animation often allows cleaner, smoother animation because images are displayed and resized using mathematical values instead of stored pixel values.
Advantages of Vector Images Because they're scalable, vector-based images are resolution independent. You can increase and decrease the size of vector images to any degree and your lines will remain crisp and sharp, both on screen and in print. Another advantage of vector images is that they're not restricted to a rectangular shape like bitmaps. Vector objects can be placed over other objects, and the object below will show through. A vector circle and bitmap circle appear to be exactly the same when seen on a white background, but when you place the bitmap circle over another color, it has a rectangular box around it from the white pixels in the image. Disadvantages of Vector Images Vector images have many advantages, but the primary disadvantage is that they're unsuitable for producing photo-realistic imagery. Vector images are usually made up of solid areas of color or gradients, but they cannot depict the continuous subtle tones of a photograph. That's why most of the vector images you see tend to have a cartoon-like appearance. Even so, vector graphics are continually becoming more advanced. Today's vector tools allow you to apply bitmapped textures to objects, giving them a photo-realistic appearance, and you can now create soft blends, transparency, and shading that once was difficult to achieve in vector drawing programs. Vector Image Software and File Formats Popular vector drawing programs include Adobe Illustrator, CorelDRAW, and Inkscape. Metafiles are graphics that contain both raster and vector data. For example, a vector image that contains an object which has a bitmap pattern applied as a fill would be a metafile. The object is still a vector, but the fill attribute consists of bitmap data. Common vector formats include AI, CDR, CMX (Corel Metafile Exchange Image), SVG, CGM (Computer Graphics Metafile), DXF, and WMF (Windows Metafile). Common metafile formats include EPS, PDF, and PICT. https://www.psprint.com/resources/difference-between-raster-vector/ ASPECT RATIO https://en.m.wikipedia.org/wiki/Graphics_display_resolution
