◆ FlipLayer()

PCB_LAYER_ID FlipLayer ( PCB_LAYER_ID  aLayerId,
int  aCopperLayersCount = 0 
)

Function FlippedLayerNumber.

Returns
the layer number after flipping an item some (not all) layers: external copper, and paired layers( Mask, Paste, solder ... ) are swapped between front and back sides internal layers are flipped only if the copper layers count is known
Parameters
aLayerId= the PCB_LAYER_ID to flip
aCopperLayersCount= the number of copper layers. if 0 (in fact if < 4 ) internal layers will be not flipped because the layer count is not known

◆ FlipLayerMask()

LSET FlipLayerMask ( LSET  aMask,
int  aCopperLayersCount = 0 
)

Calculate the mask layer when flipping a footprint BACK and FRONT copper layers, mask, paste, solder layers are swapped internal layers are flipped only if the copper layers count is known.

Parameters
aMask= the LSET to flip
aCopperLayersCount= the number of copper layers. if 0 (in fact if < 4 ) internal layers will be not flipped because the layer count is not known
