### bdl-animate-gif
```xml
<bdl-animate-gif src="heart.gif" fromid="id4" ></bdl-animatedheart>
```
Animates gif, starts and stops animation per events fmistart and fmistop from DOM id defined in attribute`fromid`.
```xml
<bdl-animate-sync-gif src="heart.gif" fromid="id4"
thresholdvalue="1e+7" refindex="8" ></bdl-animatedheart>
```
Animates gif like previous, but synchronizes the animation loop with simulation loop.
I.e. all animation frames are equally distributed among simulation cycle - start is determined by
refindex and thresholdvalue, and length is determined by simulationframes per cycle.
```xml
<bdl-animate-control
id="id5"
fromid="id4"
speedfactor="20"
segments="3;5;14;17;29"
segmentlabels="4b plnění atriální systola;1 systola komor - isovolumická kontrakce;2 systola komor - ejekce;3 isovolumická relaxace;4a plnění"
segmentcond="6,eq,0;7,eq,1;7,eq,0;6,eq,1;5,gt,0.001">
</bdl-animate-control>
```
Controls animation, defines segments - frames where animation changes state
labels which are presented and condition when met, simulation or animation is stopped.
