Andun Sameera Liyanagunawardana commented on OPENMEETINGS-731:
--------------------------------------------------------------
I have logged the value of this.area.transformation to see what happen. When
the whiteboard loads it gives,
{"m11_":-1,"m00_":1,"m12_":296,"m02_":640,"m01_":0,"m10_":0}
When we zoom in/out m11,m00 values changes and when we scroll m02, m01 value
changes. Thus can we have this kind of a example logic in the
onSetTransformation function of the scale,
if(!(m11_>-1 || m00_<1)){
#Existing Code
}
Also what should be the appropriate logic to do shifting?
> Drawing area of the Wicket based Whiteboard should be limited
