SetRect not working for bitmap annotation

I have added a bitmap annotation by AddAnnotBitmap method. Later I want to move and reposition it by annot.SetRect(float left, float top, float right, float bottom). But it is not working. It doesn't moves the bitmap in the page.But for other annotation it is working as desired. Please suggest.

Hi any update? Please suggest .

From our tests the api is working properly.
May you paste your code, please?

Thanks for your reply.
I have used onTouchAnnot to setRect for bitmapAnnot
private boolean onTouchAnnot(MotionEvent event) {
m_annot.SetRect(m_annot_rect0[0], m_annot_rect0[1],m_annot_rect0[2], m_annot_rect0[3]);
}

Hi,
can you please send us more detailed code and explanation, because this doesn't work.

Thanks in advance.
