SYStransformCoordinate

Point amount transform.

With this routine several co-ordinates can be transformed. With transformType the transformation is determined, in addition constants exist.

Parametre

px (stands in *) [IN / OUT]

py (stands in *) [IN / OUT]

In px and py become the first transformed co-ordinates zurückgeliefert.

transformType (int) [IN]

In transformType the transformation is determined.

pointCnt (int) [IN]

pointCnt gives the number of the co-ordinates in xSource, ySource, xDest and yDest.

xSource (stands in *) [IN]

ySource (stands in *) [IN]

With xSource and ySource the source co-ordinates are given. The number of the co-ordinates stands in pointCnt.

xDest (stands in *) [IN]

yDest (stands in *) [IN]

With xDest and yDest the aim co-ordinates are given. The number of the co-ordinates stands in pointCnt.
