[flexcoders] Loading modules from within AIR

[flexcoders] Can't use ImageSnapshot.captureBitmapData with a rotation matrix
Hi, does anyone have an example of using the
ImageSnapshot.captureBitmapData function with a rotation matrix? This
is the code I'm using:
var matrix:Matrix = new Matrix();
matrix.rotate(degreesToRadians(90));
var bitmapData:BitmapData = ImageSnapshot.captureBitmapData(textInput,
matrix);
But unfortunately this throws an error on the following line in
ImageSnapshot.as:
data = new BitmapData(scaledWidth, scaledHeight, true, 0x); //
-- THROWS ERROR HERE AS scaledWidth / scaledHeight are extremely
small numbers (-1-e16 etc)
data.draw(source, matrix, colorTransform,
blendMode, clipRect, smoothing);
}
finally
{
if (source is IUIComponent)
finishPrintObject(IUIComponent(source), normalState);
// -- ERROR THROWN HERE, BUT CAUSE OF ERROR IS ABOVE
}
What I'm trying to achieve is a rotated bitmap of a text input control
(I'm trying to avoid embedding a font in the application). This code
works just fine when I don't rotate the bitmap, but the minute I
rotate it, it breaks.
Any help much appreciated.

[flexcoders] Re: Can an embedded image in a module be used by the main application?
I used style.getStyle(icon) to look at the object, and it was just
the string representation from the stylesheet (@Embed(...)). Obviously
when the button style was set with this value from the module, it's
not going to find the image.
I've ditched the idea of using a stylesheet file and have defined all
the styles manually in actionscript. That way it works when embedding
images.
Thanks,
Mark

Subject: [flexcoders] Can an embedded image in a module be used by

I'm trying to load an image from a stylesheet in a module, then use
that style declaration in the main application. It doesn't seem to
work, but wondered if there is something special I need to do to get
it to work?
I have the following in my stylesheet in my module:
.sun
{
icon: @Embed(source='../assets/Background/Sun.png');
}
Then in my module I have a function like:
public function getSunStyle():CSSStyleDeclaration
{
return StyleManager.getStyleDeclaration(.sun);
}
I've checked the return value here and it does exist (I've also
checked it with simple things like background colours etc).
Now, in my main application, I take that return value and do this:
var sun:CSSStyleDeclaration = module.getSunStyle;
if (gui.controlPanelBackgroundStyle != null)
{
StyleManager.setStyleDeclaration(.sun, sun, true);
}
And I have a button (in the main app) defined as:
mx:Button x=10 y=10 label=Button styleName=.sun/
Is it possible to achieve what I'm trying to do?
[flexcoders] Can you embed a stylesheet in an actionscript project or actionscript module?
Hi, I've got a module which is written mainly in actionscript.

Is there any way to achieve this in pure actionscript? Thanks, Mark Ingram
