Performance 50ms

In general the library itself is not the final decisive factor. It all
depends on the hardware you have available, resolution of the screen, and
complexity of the the SVG data you want to render.

However, libsvg-android does NOT in itself support scripting, SMIL,or any
animation of SVG. It merely renders static SVG images. This might change in
the future, if time permits.

So lets say I do the coding to create static SVG images every 50ms which can then be rendered by the libsvg-android library to give the animation effect, but can you let me know what is the sequence of things does this library do to do the actual rendering.

I assume that it converts it into a rgb buffer, what are the steps does it execute to convert it into a rgb buffer

Does it support filling of svg paths because that is what primarily a image consists of and is it anti-aliased ?

libsvg-android works like this:

create svg-object (select if you want to do antialiasing or not)
load svg file into object (create a string object that contains the SVG)
create a canvas object
render svg object using the canvas

So, if you create a canvas that outputs to a RGB bitmap you will get the
result in that bitmap, or you can do as in this example:

http://bazaar.launchpad.net/~pltxtra/libsvg-android/main/annotate/head:/src/com/toolkits/libsvgandroid/HelloSvgCanvas.java

<http://bazaar.launchpad.net/~pltxtra/libsvg-android/main/annotate/head:/src/com/toolkits/libsvgandroid/HelloSvgCanvas.java>However;
if you have a fixed amount of frames you can render to bitmaps first, and
then blit those bitmaps to your screen. This is probably faster than
rasterising the SVG files everytime.
