Scale images to canvas? how to?

[GoogleCodeExporter]

Hello and thank you for gread library!

I'm trying to use it in my app.
Idea is to use svg icons, and render them to bitmap cache objects to fit 
different screen resolutions.

Here is code example.

SVG svg = SVG.getFromResource(getActivity(), R.raw.avatar_default);
Bitmap mBitmap = Bitmap.createBitmap(300, 300, Bitmap.Config.ARGB_8888);
Canvas c=new Canvas(mBitmap);
svg.renderToCanvas(c);
img.setImageBitmap(mBitmap);

by passing width, height I assume to scale svg to fit bitmap rectangle.

Here is example in attachment.
Selected picture is one from code above. How to scale svg to different size 
canvas? 
I also attach couple source pictures from grid on screenshot. As you see, when 
I'm trying to render svg with defaults 96x96 to 120x120 pixels Canvas\Bitmap 
I've got artefacts on picture...
I tried different scale modes on ImageViews but no luck :(

Hi swexru

I'm glad you are finding the library useful.  Thanks.

The solution to your problem is the viewBox attribute.  It tells the renderer 
what the bounds of your picture content is, so it knows how to scale it.  
Inkscape doesn't add viewBox, so you either have to add them to the file 
yourself, or add a viewBox after it is loaded, but before you render to canvas.

See the FAQ for more info.  https://code.google.com/p/androidsvg/wiki/FAQ

In your case, adding the following lines should work for all or most of your 
files:

svg.setDocumentViewBox(0, 0, svg.getDocumentWidth(), svg.getDocumentHeight());
svg.setDocumentWidth("100%");
svg.setDocumentHeight("100%");
