lpSquare|工具線上App不用買

lpSquare application is designed for the ultra-precise calculation area of the figures of any shape.

For this we need:

1. Manufacture etalon - black square 2x2 cm (can be cut from a sheet of black paper);

2. On a white sheet of paper with black paint any figure (contour) of arbitrary shape;

3. Place etalon next to a figure;

4. Make a photo of a figure with etalon so that the etalon and the figure fell completely into the frame;

5. Open the resulting image using lpSquare;

6. Select a etalon - making a long tap on the etalon (it should become red);

7. Select a figure - making a long tap inside the figure (area inside the figure should become green);

8. Tap on «CALC».

After pressing the «CALC», at the top of the screen will reveal value of the area selected figure. To deselect etalon or figure we need to re-do a long tap on the etalon or inside the figure.

The application also allows to calculate the total area of several figures.
