| 68 | planes. |
| 69 | IMP100701 : SZV ; Add ToPixMap() method |
| 70 | |
| 71 | REMARQUES : |
| 72 | ----------- |
| 73 | About FitAll() multiple. This probleme is caused by missing |
| 74 | precision of transformation matrices. If it is supposed that |
| 75 | projection is made in the plane (U,V), there is a difference |
| 76 | after several Zoom - compared to the exact value (cf ZoomX). |
| 77 | Don't forget that the matrices work in float and not in double. |
| 78 | To solve the problem (for lack of a better solution) I make 2 passes. |
