Re: [flexcoders] security issues when capturing flex screens that contain other domain bitmaps
This is generally true, but given that loaderContext wont ever change
the issue is whether it gets initialized before or after the image tag
is instatiated. If it is intialized first then I would think you dont
need the bindable tag. But again, I am not sure, which is why I
caveated it.

Re: [flexcoders] security issues when capturing flex screens that contain other domain bitmaps
I think that everytime you include the "{" and "}" it requires a
[Bindable] keyword in the scripts to be linkable. Hope that I am right on
this one.

Re: [flexcoders] security issues when capturing flex screens that contain other domain bitmaps
Yes, I did find the solution.You need to define a loadercontext. Create a loader context variable in you script section. [Bindable] private var loaderContext:LoaderContext;
NOTE: I'm not sure that it needs to be bindable but thats what my code has, so to be safe I am showing it.Then, in some initialization code, initialize the variable loaderContext = new LoaderContext(true);
Finally, when loading the graphic into an object, you must define a loaderContext and use the loader context that you just created, as below. loaderContext="{loaderContext}" verticalAlign="middle" horizontalAlign="middle" source="{picture_http}" width ="200" height="200">
Hope this helps.Regards,HankOn 11/3/06, Andrew D. Goodfellow <

The problem is that the model.picture_http is on another domain.

A policy file is
required, but the checkPolicyFile flag
was not set
when this media was
loaded.
This seems to suggest that I need a crossdomain.xml file, which
is
fine. I have that, and I believe it is in the right place. The problem
is I am supposed to set a checkPolicyFile
flag. The doc's explain how
to do this, but not in the context of Flex.
The docs say:
When you load the image using the load() method of the
Loader class,
you can specify a context parameter, which is a LoaderContext object.
If you set the checkPolicyFile property of the LoaderContext object to
true, Flash Player checks for a cross-domain policy file on
the server
from which the image is loaded. If there is
a cross-domain policy
file, and the file permits the domain of
the loading SWF file, the
file is allowed to access data in the Bitmap object; otherwise, access
is denied.
You can also specify a checkPolicyFile property in an image loaded via
an tag in a text field. For details, see Loading SWF files and
images using the tag in a text field.
I dont know how one would use the "load() " command from MXML.
Moreover, I would really like an MXMLish way to deal with cross domain
issues.
Has anybody dealt with this?

[flexcoders] security issues when capturing flex screens that contain other domain bitmaps
I have a flex screen that I want to capture into a bitmap using the
technique that Andrew Trice described earlier this week.
it works as so:
private function getUIComponentBitmapData(target:UIComponent):BitmapData{
var bd : BitmapData = new BitmapData( target.width, target.height );
var m : Matrix = new Matrix();
bd.draw(target,m);
return bd;
}

looks like this:
The problem is that the model.picture_http is on another domain.
