What is the difference between the pictures of the vector and the bitmap?

We see computer images all the time, but we rarely stop thinking about composing these images. How are they assembled? How are they manipulated? The vast majority of computer graphics fall into two categories: vector and bitmap. One is more complicated and more time consuming to create than the other, but both are widely used.

The most basic type of image in any discussion of the vector and bitmap is the bitmap image that sounds like something of the first days of calculation, a bit map. A picture of the bitmap is literally a collection of squares that together form a picture. Squares can have different colors, but all of them are the same size. Reduce any bitmap image on its part and you will see it in detail. Designers, when they talk about vector and bitmap pictures, often talk about the distinction of these pictures. That's how many dots per inch a picture. The more dots per thumb, the better the image resolution. The higher the distinction, the better the detail has the image in general; On the contrary, the lower the distinction, the smaller the picture isk.

In some cases, it may be difficult to change the size of bitmap images. When the pictures of bitmaps are reduced, some dots must be eliminated to reduce the resolution. When it enlarges, a bitmap image can appear unless it is high enough to deliver information for details of the image.

The second half of the vector and bitmap equations is the vector picture. This kind of image is much more sophisticated because it has more moving parts. Each vector image consists of a handful of smaller images, as well as bitmap, except that parts of the image of the vector are scalable. This means that designers can change the resolution of the vector image in both ARES image directions lower or increase a picture of a low -role image. If designers are looking for a picture that can be easily edited in both directions, then their choice between the vector and the bitmap should be easy.

somethingAnother thing to keep in mind in any discussion about vector and bitmap images is that vector images are not limited to a rectangular shape, as well as bitmap images. A designer who puts a vector image in another picture will not cover any of the details of the picture below. The picture of the bitmap does it because it is completely composed of square pixels, even white in the background that we do not realize, are there. This is another point that needs to be kept in mind when selecting between vector and bitmap.

, however, the key point in the discussion of vector and bitmap is that the most commonly used graphics file formats are varieties of bitmaps such as GIF, JPGS, PICTS and TIFF. This is because vector images lack the consistency of bitmap pictures in terms of photorealism. Do you need to decide between a vector and a bitmap for digital photos or pictures of a similar photo on the website, a better choice for a more photorealist picture is bitmap. Many vector images and goThese are converted into a bitmap format for use on the website. A widely known exception is the PDF file, which is a picture of the vector and looks quite good when it is not transferred.
