How many pixels is 1 cm?

Alexander Filatov leave a comment

How many pixels are contained in one centimeter - it would seem, the question is obvious, there should be no dirty tricks here. But everything is not as simple as it seems at first glance. The fact is that a pixel is not a fixed value - it is the smallest logical element of a two-dimensional raster image that has its own size, transparency, coordinates, color. Therefore, we will take a closer look at these pixel properties and, to solve the problem, we will get acquainted with such concepts as the printer resolution (DPI) and monitor screen resolution (PPI).

VKontakte and Odnoklassniki are the two largest social networks in RuNet. They have a lot of differences.

Create cartoon online by yourself

Alexander Filatov 3 comments

Once, cartoons were created only by professionals at movie studios specially equipped for this purpose. But it took a little time, and now anyone can try themselves in the role of a multiplier. There is a huge number of sites that provide the ability to create a cartoon. But the functionality of most of them is limited to the generation of motion of objects drawn by you, using the storyboard. Naturally, if you are not a professional artist, then you will not be able to create a full-fledged cartoon on such resources. Therefore, we consider in the article the best, in my opinion, service that allows you to create an online cartoon at home, namely, goanimate.com.
