Before we start by what the vector arts and Raster arts, we must understand some basic meanings :
Peculiar: In computers arts, there is a pixel component or points or an image is a material point in the image. The pixels are component small met to the title in the actress photo on the screen.
The majority of the images that we see on our computer screen are Raster
images. A self-portrait that clicks on it with your mobile is another example of a raster image. The image formed using a group from pixels units indicates to it that it is a raster image.
A raster image: In computer arts, the raster image is a designation from some fields ( For example, a range of integers ) to bits. Any values that are zero or one. Are named also bit array or bitmap index. The most generality term indicates to pixmap. In which it is possible to all the storage more than two colors, And therefore using more than from one bit per pixel. Often what is done the raster image for that also. In some contexts, the raster image term indicates one bit to each pixel, while Completing using the pixel image for the Images of the multiple bit units to all pixels.
The raster image is used in bit maps for storage information. This means that the big folder needs a big raster image. The larger the image, the Disk space that will work the image file.like an example: An image requires ( 480 x 640 ) information complete storage with size ( 307200 ) pixels, while an image needs ( 3072 × 2048 ) << From digital camera with size 6.3 Megapixel >> to storage giant information informs 6291.456 pixels. We are using Algorithms that click the format of the images Gif or Jpeg for helping in minimizing the sizes of these files. Format of the images like common compressed images. Minimizing the sizes of these images is an easy command but enlarging the raster image makes it pixelated or not clear with ease, And thus for the images that need for changing their sizes to different sizes, we use vector arts. Examples for these File Extensions are: the BMP extension ، .TIF extension ، .GIF extinction ، .and the JPG extension.
Vector Arts
Indicates to use the sequential orders or the mathematical phrases or the program that puts or counts the arts. Vector graphics are shapes in a 2D or 3D environment with the name ( Vector ) and it is the favourite for printing because it is formed from series from mathematical curves. As a result, complete printing the vector arts with a clear shape till enlarging it. In physics: The vector is a thing that has amount and direction. In vector arts, completing creating the file and keeping it as a series from vector phrases. Instead of a small part in the file to each part from the line drawing, we use the orders that describe the series from points that must connect it. File Extensions that are considered as vectors are : SVG ، .EPS ، .PDF ، .AI ، .DXF.
The changes
- Changing Vector to Raster: Prints and display devices are raster devices. As a result, we need to change the vector images to coordinate the raster before it is possible to use it, which view or print them out. Required accuracy plays a vital role in determining the size of the raster file that completed creating it. It is important here to note that the size of the vector image means that its change always stays itself. From appropriate changing vector file to a group of raster file formats but walking in the opposite path will be more difficult because we in some times need to release the image during changing from raster to vector.
- Changing raster to vector: It is possible to signal to follow the images in computing to vectorization and this is easy changing the raster images to vector images. One of the applications of interesting vectorizations is updating the images and recovering the work. It is possible to use a file ( Microsoft Windows ) for recovering information that we lost it. Microsoft Windows Paint produces a raster image output file. Jagged lines are easy to notice in the printer output file. In this type of change, the size of the image decreases with a big shape. As a result, it is impossible to Procedure flour change in this scenario. Due to the various estimations and editing were done in the conversion process, the converted images are not of good quality.
The difference between the raster arts and vector arts:
The main difference represents between the raster arts and vector arts in that the raster arts formed or gif or jpeg from pixels units, while the vector arts formed from paths. The raster art, as is an array of pixels units of the same different colors and that shaped together from an image.
