Take snapshot of drawing using FingerPaint
- by Rashmi.B
I am using MyView for drawing content on a canvas using FingerPaint API demo app. I want to capture whatever I have written on the canvas. But when I use View v1 = myview.getRootView() it is returning only the blank canvas and not the content. I want to save my drawing in SDCard. Following is my code. Let me know what do i need to change
v1 = myview.getRootView();
System.out.println("v1 value = "+v1);
v1.buildDrawingCache(true);
v1.measure(MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED),
MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED));
//v1.layout(0, 0, v1.getMeasuredWidth(), v1.getMeasuredHeight());
v1.layout(0, 0, 100, 100);
//Bitmap b = Bitmap.createBitmap(v1.getDrawingCache());
myview.mBitmap = Bitmap.createBitmap(v1.getDrawingCache());
System.out.println("BITMAP VALue = "+myview.mBitmap);
ByteArrayOutputStream bytes = new ByteArrayOutputStream();
//b.compress(Bitmap.CompressFormat.JPEG, 40, bytes);
File f = new File(Environment.getExternalStorageDirectory()+ File.separator + "rashmitest.jpg");
try {
f.createNewFile();
FileOutputStream fo = new FileOutputStream(f);
fo.write(bytes.toByteArray());
} catch (Exception e)
{
e.printStackTrace();
}
v1.setDrawingCacheEnabled(false);
myview is an object of class MyView that extends View.
