drawShape on iOS #1402

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
I have free hand drawing component previously implemented in pisces drawing 
line by line but on iOS it was terribly slow.
I change the implementation using com.codename1.ui.Graphics  and the method 
drawShape. It's perfectly fast on Android but on iOS my application freezes (no 
error message, just not responding).

test case in attachment.

Just place the SignComponent in Form f:
SignComponent sign = new SignComponent(f);
f.addComponent(sign);

I think I see the problem.   iOS doesn't yet support drawShape for mutable 
images.   There still may be a bug here as I thought it should have failed 
gracefully if you call drawShape() on a mutable image.

Support is planned but not sure when I will have a chance to complete it.

in method paintBackground I'm not drawing on mutable image
(only in getImage() which I use for saving image later, you can ignore it for 
this testcase)

Fixed.  The problem was that it was choking on drawing an empty shape.

Will be included in the next server update (probably within next couple of 
days).
