Understanding SVG Rasterization

[Mustafa Sezgin <ms...@internode.on.net>]

Hey all,

I am someone wanting to gain a better understanding of how
the SVG file or DOM model is converted to raster image,
specifically onto a canvas thus RGBA based image. I have
looked into the transcoders but I cant seem to find where
the shapes stored within the DOM tree are actually converted
into the required RGBA format. If you guys could just give
me some information on where I am clearly not looking, that
would be great :)

I am just interested in how Bezier curves and some shapes
are rendered.

Thanks in Advance...

    We rely mostly on the Java2D API's to convert the 
various vector shapes into raster content.  The code
that uses the Java2D API is mostly in the batik.gvt package.

    If you are looking at how to do it with Java2D take a 
look at the GVT classes.  If you are looking at how to do
it without a supporting library you will have to look
elsewhere.
