Raster graphics The smiley face in the top left corner is a bitmap image. When enlarged, individual pixels appear as squares. Zooming in further, they can be analyzed, with their colors constructed by adding the values for red, green and blue. In computer graphics, a raster graphics image, or bitmap, is a dot matrix data structure representing a generally rectangular grid of pixels, or points of color, viewable via a monitor, paper, or other display medium. A bitmap corresponds bit-for-bit with an image displayed on a screen, generally in the same format used for storage in the display's video memory, or maybe as a device-independent bitmap. Etymology[edit] The word "raster" has its origins in the Latin rastrum (a rake), which is derived from radere (to scrape). Resolution[edit] Raster-based image editors[edit] Scanned-display computer graphics[edit] An early scanned display with raster computer graphics was invented in the late 1960s by A.

Vector graphics Example showing effect of vector graphics versus raster graphics. The original vector-based illustration is at the left. The upper-right image illustrates magnification of 7x as a vector graphic. Overview[edit] Computer displays are made up from grids of small rectangular cells called pixels; the term comes from "picture elements". A vector-based image of a round four-color swirl. Modern displays and printers are raster devices; vector formats have to be converted to raster format (bitmaps – pixel arrays) before they can be rendered (displayed or printed). In computer typography, modern outline fonts describe printable characters (glyphs) by cubic or quadratic mathematical curves with control points.[4] Nevertheless, bitmap fonts are still in use. Standards[edit] The World Wide Web Consortium (W3C) standard for vector graphics is Scalable Vector Graphics (SVG). There is also a version of SVG for mobile phones. Detail can be added or removed from vector art. Applications[edit] Formats[edit]

Creating Seamless Backgrounds with the GIMP | Gimp Tips ---- GIMP Tips, Tricks, Tutorials and Techniques ---- Using the GIMP it is an easy process to make seamless background images. The background images on web pages are a good example of seamless images. They are generally small images which are tiled or displayed repeatedly by your web browser. Image 1: Tiled With this image I have simply tiled the original image 4 times using the "Filters > Map >Tile" tool. As can be seen from this example, a tiled images may not be seamless. Image 2: Seamless and Tiled The Seamless background is easily achieved without too much effort. This is what our our seamless image looks like when it is tiled 4 times. Image 3: Re-sized Seamless and Tiled Background Image 2 was re-sized "Image > Scale Image" down to 28 x 28 pixels. Tip: When creating backgrounds.
