[forms-devel] Intent of Image.IsOpaque

[이승근]

Hi, all

Who is known intent of Image.IsOpaque?

It only implemented in iOS, others platform renderers ignore this property.

Anyway, Currently Xamarin document describe this property like below
https://developer.xamarin.com/api/property/Xamarin.Forms.Image.IsOpaque/
"If true, you'll be able to see through transparent parts of the image."
According to this guide, If want show partially transparent image, IsOpaque
should be set true.
Is that right?

As I know, IsOpaque property was mapped iOS UIView.opaque
https://developer.apple.com/library/ios/documentation/UIKit/Reference/UIView_Class/#//apple_ref/occ/instp/UIView/opaque
"You should always set the value of this property to NO if the view is
fully or partially transparent."
According to this guide, If want show partially transparent image, opaque
should be set false(NO)

Which is right?
Please, anyone answer this question.

Thanks!
