private floattoPixel(Resourcesres, intdip)
{
floatpx=TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP,
dip,res.getDisplayMetrics());
returnpx;
}

publicBitmapcreateBitmap(Bitmapsrc,Stringstr)
{
DisplayMetricsmetrics= newDisplayMetrics();

getWindowManager().getDefaultDisplay().getMetrics(metrics);

intw=src.getWidth();
inth=src.getHeight();

intscreenWidth=metrics.widthPixels;
intscreenHeight=metrics.heightPixels;

intheight=( int)960*68/screenHeight;
BitmapbmpTemp=Bitmap.createBitmap(w,height,Config.ARGB_8888);
Canvascanvas= newCanvas(bmpTemp);
Paintp= newPaint();

Typefacefont=Typeface.create(Typeface.DEFAULT,Typeface.BOLD);
p.setColor(Color.GRAY);
p.setTypeface(font);

intfontSize=( int)toPixel(getResources(),11);

p.setTextSize(fontSize);
p.setTextAlign(Align.CENTER);
canvas.drawBitmap(src,0,0,p);

inty=( int)960*63/screenHeight;
intx=( int)screenWidth/10;

intadjustWidth=( int)(screenWidth/10-(screenWidth-5*w)/10);

if(adjustWidth<x
&&adjustWidth>0)
{
x=adjustWidth;
}

canvas.drawText(str,x,y,p);
canvas.save(Canvas.ALL_SAVE_FLAG);
canvas.restore();
returnbmpTemp;
}
