Annotation Support in iOS

I need to implement following annotations:

Free text annotation
Polygon
Polyline
Cloud
Measured Circle
Calibrator
Measured Rectangle
Callout
Multimedia Embed
Stamp

So, are these annotations possible in Radaee and If possible then how I should proceed?

can't create:
Cloud
Calibrator
Callout
Multimedia Embed
others are OK.

you can also manage Multimedia annot:

to add it, you can use addAnnotAttachment method.

if you want a multimedia viewer, as Android version, you should implement it with native objects
