There is a big difference between Vector graphics and Raster Graphics since the latter is usually colored pixels assembled to show images while in the former, mathematical formula is used and the name vector is applied. The formula displays the path giving details of the color (both the fill and the surroundings) and the shape.
Most people would probably be happy to know the main difference between the two graphics. For clarity, let us zero in on the image difference between the two groups. Raster images can as well be referred to as bitmaps and mainly comprised of individual pixels of color. It is the combination of these pixels that contributes to the overall image. A single pixel cannot make any significant meaning, but it displays an image when viewed as an aggregate. It is important to know that Raster images have the capacity to display complicated yet colored visuals, which may include a soft color gradient as well. Incidentally, digital cameras generate raster images. Moreover, all photographs in print and online are also raster images.
Raster files have different formats. The main ones are GIF, PING, and JPG. Mostly, raster images find their use in digital printing services and photo editing. The main program supporting it being Photos hope and GIMP. The beautiful thing about these formats is they can easily be compressed for Web optimization and storage purposes. The number of pixels-per-inch governs the quality of the raster image. This measure is, in most cases, abbreviated as ppi. Quality of raster image can also be determined by the bitmap's overall dimensions, equally expressed as pixels. Therefore, the greater the concentration of pixels per inch and dimensional measurement, the better it is quality. Notably, most images must have more than 300ppi per inch to be viewed as quality work. If you happen to scale images, the images become blurry because the number of pixels per inch has changed. There is, however, no harm scaling down, as is the case of Web images.
On the other hand, since mathematical formulas determine the image quality, vector images maintain their appearance regardless of their sizes. They can easily be scaled up without compromising their quality. The main programs that find vector Graphics useful include Illustrator, Inkscape, and CorelDraw. The fact that these applications are designed to use simple solid colors, the use of vector graphics becomes appropriate. Unlike raster images, vector images carry a certain shape with a definite color to go with it. As a result of this, it becomes incredibly difficult to get color shadows, shadings, and gradients easily achieved with raster graphics. A true vector image is composed of line art filled with a color that is quality known as wireframes. Considering that you can easily scale vectors without much of a problem, designing logos and printing stickers that do not include photos become common with the graphics. Other areas that find vector graphics useful are embroidery, engraving, product artwork, and signage. Though the SVG format of a vector can be used on the Web without alteration, other formats like AI and CDR must be rasterized (mimic them as rasters).
All in all, raster images have the capability to show a variety of colors within the same graphic with ease of color editing, which is usually not the case for vector images. Normally, in situations where the vector graphic is applied, rasterization usually offers true-to-life images, limitation of dimensional size, and resolution notwithstanding. When the two graphics types are subjected to EPS and PDF format, the software that generated them usually dictates the result format. However, it is possible to convert SVG to PNG. All that is needed is to ensure that proper procedure of conversion is properly adhered to when converting the same.
