4 | // Class AliMpTransformer | |
5 | // ---------------------- | |
6 | // Class contains definition of transformation and | |
7 | // provides functions for transforming pads. | |
8 | // | |
9 | // Transformation of pad characteristics according to sectors: | |
10 | // | |
11 | // I. ( posId, Guassi ), ( i, j), ( x, y) II. | I. | |
12 | // II. ( posId', Guassi'), (-i, j), (-x, y) _____ | ____ | |
13 | // III. (-posId, Guassi), (-i,-j), (-x,-y) | | |
14 | // IV. (-posId', Guassi'), ( i,-j), ( x,-y) III. | IV. | |
15 | // | |
16 | // Where (posId', Guassi') is the location of the pad | |
17 | // in the clipped sector. | |
18 | // | |
