![]() They will always appear computer generated. Vector graphics are never going to be as lifelike as bitmaps or photos. For example, if each pixel is represented by 4 bits, then a given pixel can be assigned one of 16 different colors (24 16). The number of bits devoted to an individual pixel determines the number of colors that can be assigned to that pixel. A vector graphic the size of a postage stamp could be resized to be used on a poster and the image would still be clear. A bitmap is an array of bits that specify the color of each pixel in a rectangular array of pixels. Scalable - when you resize a vector graphic the mathematical relationships mean that the image does not lose quality.For a large illustration, such as a poster, a vector graphic would have a significantly smaller file size compared to a bitmap image. ![]() We can create bitmap graphics in Photoshop, as well as a number of other programs, like GIMP and and Krita. Bitmap graphics have a set resolution, or number of pixels in the document. Each pixel in a bitmap graphic corresponds to a pixel on a users screen. Smaller file size - vector graphics, unlike bitmap images, do not store data about each individual pixel. Examples of bitmap graphics include digital photographs.GDI+ supports the following file formats: BMP, GIF, EXIF, JPG, PNG, and TIFF. There are many standard formats for saving a bitmap to a file. A stroke follows the outline of the vector path and a fill adds a colour to the area inside the path. A bitmap consists of the pixel data for a graphics image and its attributes. It is possible to edit each object separately, for example, change the shape, stroke, fill, size and position. Vector objectsĪ vector object is a shape made up of vector paths. These points are connected by lines and curves called vector paths or vectors. Information is not stored about each pixel. Vector graphics are based on mathematical relationships with control points that make up the image. Generally a drawing package offers many similar features to a painting. ![]() Drawing packages are also known as vector drawing packages. Images made with drawing packages consist of lines, shapes and co-ordinates.
