I don't have Matrix object as I get the annotation as:
m_annot = page.GetAnnotFromPoint(m_annot_pos.x, m_annot_pos.y);

I have to extract Matrix object from m_annot.
How can I get it?

You can use Annotation.GetMarkupRects() to construct the matrix,
Or if you intercept the annotation creation, you can save index1 and index2 and use www.androidpdf.mobi/documentation/javado....html#AddAnnotMarkup(int, int, int) instead

it's a reference to the javadoc
www.androidpdf.mobi/documentation/javadocs/
www.androidpdf.mobi/documentation/javado....html#AddAnnotMarkup(int, int, int)
