Standarts

Standards for graphics, they are all different. They can be classified into various groups. Below we will examine two groups of RDC, we can distinguish them.

Separated By Size

In this division we consider standard sized proportions imposed time. The main factor for the division size is the resolution of the images, and rather snoynosta windage and elevation. A typical size is 640x480 resolution. Resolution set to pixels and 640x480 is the size specified interplotira that has 640 pixels horizontally and 480 pixels vertically. The resolution is 640x480 pixels ravanyava of 0.3Mpx. As we will show below in tabular format standard resolutions and hence their size in megapixels.

Separated By Type Of File

Graphic images on computers in razlinchi file formats. Among the most popular are JPG, BMP, PNG, etc. .. Each format has its advantages and disadvantages. Mainly divided on the image quality. As a large format graphics allow to keep a Mlaka place, but at the expense of quality and partial loss of information most often not visible to the naked eye.

Converting Of Image Files

Converting images is done for compatibility with various applications. When we have an image that is uncompressed format display it on the internet leads to slower loading the image. To this end, we convert it into a suitable format is easier to access. In this way we achieve and saving space for image storage. Different graphic editors work with different file formats.
