Photographs are raster images and are probably the best example of images completely made of color blends - or shade blends in the case of black and white photographs - and those images look very different when drawn in vector format. A vector graphic with gradients contains both vector and raster elements and won't be suitable for process that requires 100% true vector art such as cutting or engraving. Some vector programs do have the ability to create color gradients within one single shape, but these are actually raster effects. Images with a subtle gradation of one color to another are the images that will look most different since vector programs need to create a separate shape for each shade of color. FIG.2Ī lot of images can be made with either raster or vector program and look exactly the same on both programs. These shapes, called objects, display one single color each. When using a vector program you draw the outline of shapes, and it's similar to creating an image with tiles of all different shapes and sizes. By using a multitude of pixels of different colors a gradual transition from one color to another can be created a soft blend of colors. When using a raster program you paint an image, and it's similar to dipping a brush in paint and painting. Vector graphics are math-defined shapes created with vector software and are not as common used in CAD/engineering, 3D animation, and in Graphic Design for processes that reproduce an image on an object without ink or paint, such as engraving, etching, cut stencils. They are more common in general such as jpg, gif, png, and are widely used on the web. Raster images are created with pixel-based software or captured with a camera or scanner. There are two main type of image files: Raster and Vector.
