Basic terms and concepts

Framing – a selection of borders, and the size of the image. Usually, it is used to produce a more balanced picture.

Practical value

The service was developed primarily to facilitate filling with photos the KrokApp mobile application. It is the audio guide for the cities of Belarus [1]. The service allows cutting images in the format that is necessary for filling the content database of KrokApp without the difficult graphics editors, only in three clicks. In particular, the image of the sights in the program should have a size of 800×533, and its photo on preview page should be a circle with a diameter of 100 pixels in .png format.
