Colour Depth Color depth, also known as bit depth, is either the number of bits used to indicate the color of a single pixel
Metadata A set of data that describes and gives information about other data.
Vector Graphics Vector graphics is the use of geometrical primitives such as points, lines, curves, and shapes or polygons—all of which are based on mathematical expressions—to represent images in computer graphics.
Bitmap Graphics A bitmap graphic is composed of many tiny parts, called pixels, which are often many different colours. It is possible to edit each individual pixel.
Raster Graphics Raster graphics are digital images created or captured (for example, by scanning in a photo) as a set of samples of a given space. A raster is a grid of x and y coordinates on a display space.
