How to get a perfect box cutout with Screen Protractor

[Togijak]

 

you position the protractor on a corner of the box

 

 

and determines the angle of inclination

 

 

 

now turn the image according to the value determined against the clockwise sense

 

 

and turn it back afterwards

 

 

then determines the second value

 

 

 

note that you have to use a color that is not used in the picture

 

 

now you can choose the color used

 

 

in order to avoid color borders, the selection is reduced by 1 pixel before copying and thus receives a perfectly isolated box shot
