Detailed Description

The Angle class is used to represent an angle (for example 12.75 degrees)

This class is used to represent ALL angle values in Symbols, Schematics, Footprints, Layouts and so on. You should never use another angle type, like integer or float! It's very important to have a consistent angle type over the whole project.

An angle is normally interpreted as a CCW rotation from the horizontal line:

Y
^   /
|  /
| /  +60°
|/
+--------> X

Warning: Please note that the Qt Graphics Framework (QGraphicsView/QGraphicsScene) may interpret an angle as a CW rotation! So you may need to negate the angle first when used for a rotation in the graphics framework.

All angles are stored in the integer base type int32_t. The internal unit is always microdegrees, but this class provides also some converting methods to other units. The range of the angle is ]-360°...+360°[. So each angle (except 0 degrees) can be represented in two different ways (for example +270° is equal to -90°). Angles outside this range are mapped to this range (modulo), the sign will be the same as before.

If you don't want an (ambiguous) angle in the range ]-360..+360[ degrees but [0..360[ or [-180..+180[ degrees, there are converter methods available: mappedTo0_360deg(), mapTo0_360deg(), mappedTo180deg(), mapTo180deg().

There are also some static method available to build some often used angles: deg0(), deg45(), deg90() and so on...
