Note also that, as a higher-level abstraction, vector may include bitmaps as a special kind of object. Still, with Inkscape's gradients and transparency, you can create amazingly photorealistic vector images. photos) in bitmaps, you cannot easily simulate very complex graphics with vectors. While you can store arbitrary graphics (e.g. The only downside of vectors is that you are limited by the types of objects and properties that your drawing tool and vector format support. Another analogy: vectors are like the source code of a program, while bitmaps are compiled binaries. If you are into digital music, you may better understand it if I compare vector graphics to MIDI and bitmap graphics to a sound recording. It's very easy to pick an object from a drawing and insert it into another drawing. Since vector objects are similar to how we (humans) tend to think about drawings, and since many vector formats (including SVG) are text-based, it is easy to write a simple vector drawing manually (without graphic editor of any kind) or program a script to generate such a drawing, e.g. A drawing can change any properties of objects in response to user actions, which makes it possible to implement complex interfaces with buttons, links, drag-and-drop, etc. Not only can you animate objects, you can make them interactive as well. That's why vector formats such as SVG or Flash usually support animation as well. Since in a vector drawing, objects are stored separately, it's easy to animate them by moving, transforming, etc. You can view or export your drawing at any resolution, and you'll never see any jaggedness or "zoom blur." Everything remains crisp regardless of size. By contrast, there's no need to ever "flatten" a vector drawing (you can export it to a bitmap, though). In a bitmap editor, you are supposed to eventually "flatten" your image, so even if different objects were on different layers, they're no more. Unless you delete some object, it's always as easy to separate from others and edit as always. The depth of "undo" is a much less limiting factor in Inkscape than in a bitmap editor. Here are the main advantages of the vector approach: That's how Inkscape works, and that's its main point of difference from bitmap editors such as GIMP. Moreover, computer can do a lot of things automatically! No more frustrating "selections", just pick any object and edit it as necessary. This means you can easily separate it from other objects and do whatever you please with it. In a vector format, the actual circle can be stored, along with its properties, as an object. smoothed so that some pixels are half-black, half-white). These kinds of tasks may be difficult even for humans, as anyone who've used The Gimp or Photoshop would attest: you'll have to use complex and unreliable tools to "select" the circle, and you still cannot do this perfectly if, for example, the edges of the circle are anti-aliased (i.e. It can paint all white pixels blue, but it cannot move or transform the circle because it does not "see" it. All that the computer knows about the image is that some of its pixels are black and some are white.Īs a result, there is little the computer itself can do with such an image. It stores information about what is the color (and, possibly, transparency) of every pixel of the image - but nothing else.įor example, if you have a PNG image with a black circle on white background, in fact there is NO black circle stored in the image at all: it's only the person viewing this image who can "guess" that it displays a circle. A bitmap, however, is a very low-level abstraction. The majority of images stored and processed on computers today are bitmaps. Inkscape is a vector editor, not bitmap (raster) editor.
