Data Transformations

The Gerber Union user may need to apply certain transformations to the data after Boolean operations. Gerber Union supports the following transformations which are available from the Advanced menu on on the gbrrunmgr command line:



Examples - Transformation and Images

We will illustrate the behavior of the transforms using a simple Gerber file as shown below:


Case 1: No Transformation

bitmap: no mirror, scale 1, rotation 0
bitmap: no mirror, scale 1, rotation 0


Case 2: Mirror X

mirror X means x -> -x; not mirror about the X-axis.

 

bitmap: mirror along x, scale 2, rotation 0


Case 3: Mirror Y

mirror Y means y -> -y; not mirror about the Y-axis.

 

bitmap: mirror along x, scale 2, rotation 0


Case 4: Mirror X and Rotate 90°

Mirroring is performed before rotation. Rotation is CCW

 

bitmap: mirror along x, scale 2, rotation 90 deg
