Topic: Raster graphics


  
  Raster graphics
Raster graphics are the only reasonable choice for photos and satellite images.
Vector graphics can be converted to a raster graphic with a specified resolution, as is almost always the case before printing, except for "pen plotters".
Raster graphics cannot be converted back to vector graphics.

Please see the W3C Graphics Activity statement to find out what W3C is currently doing and has already done in the area of Web Graphics, including SVG, WebCGM Profile, and PNG.
SVG, a vector graphics format designed at W3C, written in XML and stylable with CSS, is starting to become a popular choice for including graphics in XML documents.
The IMG element is the most common method for using graphics in HTML pages.

 University Graphics -- About File Formats
One advantage of vector graphics is that they exhibit something called "device independent resolution." This simply means that they will always display or print at the highest-possible resolution since the image is transmitted mathematically to whatever display device is used.
Raster graphics are created and stored using "pixels" to describe the image.
A significant disadvantage is that raster images are much more dependent on resolution, which is a factor of their physical size often expressed in dots-per-inch (dpi), and they generally cannot be resized larger without diminishing their quality.

 Graphics
Raster graphics represent graphical images as a pattern of dots, called a bit map (this is why raster graphics are also called bit-mapped graphics).
Vector graphics are images created by geometrical instructions or mathematical formulae that contain information about the location and characteristics of various lines, curves and shapes.
The difference between outputting vector graphics and raster graphics, therefore, is that vector graphics are not translated into bit maps until the last possible moment, after all sizes and resolutions have been specified.

 Print Understanding Vector and Raster Graphics
Vector graphics applies geometrical standards i.e., lines, curves, and polygons to represent images, while Raster graphics or a bit-mapped image, which is based on pixels in a grid, and contains information about the colors to be displaced in "bits".
Vector graphic are perfect format for the Web as these are lightweight graphics to the websites due to its file size and problem free regarding physical height and width of the image.
While, dot-matrix printers, laser printers, and monitors, are raster devices, this means that all objects, even vector objects, must be translated into bit maps before being output which means, even vector graphic images must be interpreted to the raster graphic before the end product can be displayed on paper.

Compared to the live CD edition, users now have a choice of KOffice (1.3.5) and GNOME Office (AbiWord + Gnumeric), in addition to OpenOffice.org (a recent beta of the 2.0 series).
It seems like a really useful community project would be to develop an application menu registry and a standard application menu.
You submit a request to the menu registry group, saying you've got this graphics program that manipulates raster graphics.

  Volume Graphics
Volume graphics, which is the subject of this paper, is an emerging subfield of computer graphics concerned with the synthesis, manipulation, and rendering of volumetric objects, stored in a volume buffer of voxels.
Raster graphics utilizes a 2D frame-buffer (a raster) of pixels for scene representation and a point-based renderer for coloring those pixels that correspond to the discrete representation of the geometric objects.
In addition, the raster representation lends itself to block operations, such as bitblt (bit block-transfer), in which a window or a rectangular block of pixels can be rapidly transferred with a variety of pixel-by-pixel operations between the source and destination blocks (row 6) [4].

Vector graphics stores precise geometric data, topology and style such as: coordinate positions of points, the connections between points (to form lines or paths), and the color, thickness, and possible fill of the shapes.
Raster graphics is a uniform 2-dimensional grid of pixels.
Today's graphics are not only the product of massive collections of polygons into recognizable shapes, but they also result from techniques in shading, texturing, and rasterization.

Not all fonts used in Windows are true type fonts, these raster fonts consisting of bitmap definitions of each glyph can not be scaled to very large size, but they generally have the bitmaps for most used point sizes.
If the raster image must be used (such as to images in the Internet), you can generate two raster images, one for viewing from the screen, one for printing.

 Raster Images versus Vector Images
Raster images are created through the process of scanning source artwork or "painting" with a photo editing or paint program such as Corel PhotoPAINT or Adobe PhotoShop.
The resolution of a raster image or scanned image is expressed in terms of the dots per inch or dpi.
The quality of an imprint produced from a raster image is dependant upon the resolution (dpi) of the raster image, the capabilities of the printing technology and whether or not the image has been scaled up.

The difference between vector graphics and raster graphics from a printing viewpoint, therefore, is that vector graphics are not translated into bit maps until the last possible moment, after all sizes and resolutions have been specified.
For example, a graphic in certain cases (such as a roadmap) could be conceptualized as consisting of several "components." Then, each of these different components of the same graphic could be created by different authors, even reside in different places, and when called upon (HTTP or viewer request) presented transparently in a single SVG graphic.
Computer graphics is playing an increasingly significant role in various fields of study, such as Geometry, concepts from which were previously were difficult to represent on paper or flboard, for a variety of reasons.

When you are involved in the creation of graphics, you often have to decide whether to use a raster or a vector format.
Vector-based data is especially suitable for the creation of graphics containing elements like lines, rectangles, text, etc. These are always displayed plain, and the size of the whole graphic can be changed arbitrarily without loss of quality.
If your graphics are not meant to undergo further scaling and the file size does not matter, it makes sense to use a raster format.

 Importing Graphics into Flash > Vector Graphics Versus Raster Graphics   (Site not responding. Last check: )
Vector graphics have two advantages: The file size tends to remain small (therefore, it downloads fast), and the image can be scaled to any size without any degradation of the image quality (a circle is still a circle, even if it’s a large circle).
Vector graphics require the user’s computer to work hard to display the image (it has to do a lot of math), and vector graphics often look "computery" or antiseptic because they tend to involve geometric shapes.
However, the decision of whether to use vector graphics or raster graphics should be based on the nature of the image.
