Thx patmo, great that you take the time to point me to this adjustment!
All the best, fellow addon maker.
EDIT : put bindcode code in v2.2.1
version 2.2.2
fixed some bugs
version 2.3.0
There was a major bug in the addon, which made the reerence images disappear when an other object was selected! Nobody reported this, strange…
But, whatever, TranspRef now works fine in prespective mode too, without image distortion.
version 2.5.0
Quite some things changed, rewritten and fixed.
