|
|
* This attribute can only be used when the file represents a pattern in a material layer,
|
|
* e.g. copper, solder mask, legend.
|

* Together with.FileFunction it defines the role of that image in
|
|
* the layer structure of the PCB.
|
|
* Note that the .FilePolarity attribute does not change the image -
|
|
* no attribute does.
|
|
* It changes the interpretation of the image.
|
|
* For example, in a copper layer in positive polarity a round flash generates a copper pad.
|
|
* In a copper layer in negative polarity it generates a clearance.
|
|
* Solder mask images usually represent solder mask openings and are then negative.
|
|
* This may be counter-intuitive.
