MIRROR

A transformation that mirrors positions across the line through two points.

Syntax

MIRROR(p,q)

Argument	Meaning
p, q	Two different positions on the line to mirror across. The line can be at any angle.

Result

A transformation.

Examples

In the example drawing:

Expression	Gives
`P6*MIRROR(P1,P2)`	`[940,80]`
`P6*MIRROR(P0,P1)`	`[60,-80]`
`P6*MIRROR(P0,P2)`	`[98.8235,15.2941]`
`P6*MIRROR(P0,[1,1])`	`[80,60]`

Notes

A transformation is used by multiplying a position by it: P1*ROTATE(P0,90). The Transform tool writes these. The line follows the points it is defined by. Mirroring twice across the same line puts a position back where it was.
