7fd59977 | 54 | 29-OCT-98 : DCB : Adding ScreenCopy () method. |
7fd59977 | 55 | REMARQUES : |
56 | ----------- | |
57 | About FitAll() multiple. This probleme is caused by missing | |
58 | precision of transformation matrices. If it is supposed that | |
59 | projection is made in the plane (U,V), there is a difference | |
60 | after several Zoom - compared to the exact value (cf ZoomX). | |
61 | Don't forget that the matrices work in float and not in double. | |
62 | To solve the problem (for lack of a better solution) I make 2 passes. | |
