[forms-devel] Add IsAnimatedImage and IsPlaying to Image

[sh min]

Hello,

Thanks for you reply, IsAnimated looks better.

About your question, IsPlaying property is to start/stop animation. It can
be used after loading of the image and it is related to how the image
displayed.
So, I thought that it can be added to Image class.

Could I ask why you think that ImageSource is more appropriate than Image?

Best Regards,
Sunghyun Min
