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