We can't found above methods.
And we need code for addBitmap annotation in PDF using Bitmap object.
So send actual code which work for Bitmap annotation.

Note:
In our application we used three types annotation.
1 Text
2 ink
3 Bitmap

above two working well but bitmap annotation not added in PDF.
Some time annotation added with blank bitmap.
means bitmap not displaying on PDF but rectangle of bitmap displaying.

here is piece codes in PDFReader:
PDFPos pos = m_view.vGetPos(touch_x1, touch_y1);
PDFVPage vpage = m_view.vGetPage(pos.pageno);
Page page = vpage.GetPage();
if( page != null )
{
Matrix mat = vpage.CreateInvertMatrix(m_view.vGetX(), m_view.vGetY());
float rect[] = new float[4];
rect[0] = touch_x1;
rect[1] = touch_y1;
rect[2] = touch_x2;
rect[3] = touch_y2;
mat.TransformRect(rect);
page.AddAnnotBitmap(m_icon, true, rect);
mat.Destroy();
m_view.vRenderSync(vpage);
}
where touch_x1, touch_y1, touch_x2, touch_y2 is in screen x,y.
touch_x2 > touch x1 and touch_y2 > touch_y1

We tried above code but still same issue.
We are using code as below.

m_doc.SetCache(Global.tmp_path + "/temp.dat");
int c_page = Constant.currentpage;
pa = m_doc.GetPage(c_page);
pa.ObjsStart();
PDFVPage vpage = m_rPDF.m_view.vGetPage(c_page);
float[] rect = { 200, 200, (200 + bitmap.getWidth()),
(200 + bitmap.getHeight()) };
pa.AddAnnotBitmap(bitmap, true, rect);
float m_ratio = ((float) m_doc.GetPageHeight(c_page))
/ ((float) m_doc.GetPageWidth(c_page));
Matrix mat = new Matrix(m_ratio, -m_ratio, 0,
m_doc.GetPageHeight(c_page) * m_ratio);

pa.RenderToBmp(bitmap, mat);
m_rPDF.m_view.vRenderSync(vpage);
pa.Close();
mat.Destroy();
bitmap.recycle();

Please let us know what modification it needs.

m_doc.SetCache(Global.tmp_path + "/temp.dat"); can't invoke multi-times.
only once m_doc.SetCache can be invoked, for each Document.

Still same problem..
