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. | |
