No, but If you do not want to save, then you need to get the annotation info before closing, as by closing the document and/or page object you will lose all the modifications.

For the second question make sure to rerender the page after adding the annotation, by calling PDFView.vRenderSync or PDFView.vRenderAsync

We are getting the annotation before closing the document, but only the current page is returning the annotation.

For setting the annotation, I´m trying with this two methods, but It is not print in the pdf.

PDFPage page = m_doc.GetPage(0);
page.AddAnnotEllipse(rect, strokeWidth, color, icolor);
PDFVPage vPage = m_view.vGetPage(0);
m_view.vRenderSync(vPage);

PDFVPage vPage = m_view.vGetPage(0);
PDFPage page = vPage.GetPage();
page.AddAnnotEllipse(rect, strokeWidth, 12821, 51212);
m_view.vRenderSync(vPage);

Thanks.

To avoid this problem, you can get the annotation immediately after it has been added to the page.
i.e. in PDFView.cs for example

Code:

if (page.AddAnnotxxx())
 {
            PDFAnnot annot = page.GetAnnot(page.AnnotCount - 1);
}

To refresh after adding an annotation you need also to call vDraw:

Code:

PDFPage page = m_doc.GetPage(0);
PDFRect rect = new PDFRect();
rect.bottom = 488.476563F;
rect.top = 206.476563F;
rect.right = 377.80426F;
rect.left = 566.2051F;
float strokeWidth = 0.8957775F;
page.AddAnnotEllipse(rect, strokeWidth, 0xffffff00, 0x50ffff00);
PDFVPage vPage = vGetPage(0);
vRenderSync(vPage);
vDraw();
