zoom-canvas 1.0.1 [L3 ] 9-jun-2013

  • Bugfixing - (mitigated) "zoomfit" bug
    • "zoomfit" method was inherently imprecise due to underlying bbox command whose "return value may overestimate the actual bounding box by a few pixel".
    • Now "zoomfit" method is simply "less" imprecise
    • Now "zoomfit" takes care of canvas border and highlightthickness, too.

zoom-canvas 1.0.2 [L4 ] 19-jun-2013

  • Bugfixing - Added missing C2V and V2C methods !
