About

Rounding shape

Read full description

Rounding shape is a graphical editor that allows you to create and modify geometric shapes. The main feature is the ability to round the corners of geomemetric figures to the desired radius, and also allows you to change the width and height of the figure and reduce or increase the thickness of the stroke, as well as select the color of the shape from the palette. The application allows you to export the resulting shape to a png file. This application accelerate your work with graphic programs.
