示例1: createBitmap
import android.graphics.Canvas; //導入方法依賴的package包/類
public static Bitmap createBitmap(InputStream in, int w, int h, boolean closeStream) {
if (in == null) {
return null;
}
com.larvalabs.svgandroid.SVG svg;
svg = new SVGBuilder().readFromInputStream(in).build();
Bitmap bitmap = Bitmap.createBitmap(w, h, Config.ARGB_8888);
Canvas canvas = new Canvas(bitmap);
Picture pic = svg.getPicture();
// svg.renderToCanvas(canvas/*, new RectF(0f, 0f, (float)w, (float)h)*/);
// svg.renderToCanvas(canvas, new RectF(0f, 0f, (float)w, (float)h));
canvas.drawPicture(pic, new Rect(0, 0, w, h));
if (closeStream) {
try {
in.close();
} catch (IOException e) {
throw new RuntimeException(e);

/**
* Original author nimingtao wrote that this method may not work on devices with Ice Cream Sandwich (Android v4.0).<br/>
* See: http://stackoverflow.com/q/10384613/1084488<br/>
* Apparently this is because canvas.drawPicture is not supported with hardware acceleration. If the problem occurs
* and solved by programmatically turning off hardware acceleration only on the view that will draw the Picture:
* view.setLayerType(View.LAYER_TYPE_SOFTWARE, null);<br/>
* <br/>
* However, I (mstevens83) was unable to reproduce this problem on an emulator running Ice Cream Sandwich, nor on
* physical devices running Jelly Bean (v4.1.2 and v4.3 tested).
