Hi again,

I am going to need some help here. I could not found a example to explain how to use this new method: AddAnnotEditbox()

So imagine that I want to place a text in coordinates (100px, 80px) of PDF file.
How should I use this method?
page.AddAnnotEditbox(matrix, rect, tsize, 0x00FF0000);

-matrix -> should I worry about this?
-rect - > "left, top, right, bottom in DIB coordinate system." this seems to be easy if DIB means px of PDF file.
-tsize ->"test size in DIB coordinate system" test? What this means?
-color -> this is clear for me

What DIB means?
How should I know the size of the box If this is going to depend on the font to be applied on this box?
How should I apply the font?

Best regards

sorry, we write Matrix as int, this is wrong.
we will fix it in next version.
to add edit box you need codes like this:

			bitmap.eraseColor(0xFFFFFFFF);
			Page page = m_doc.GetPage(pageno);
			if( page != null )
			{
				Matrix mat = new Matrix(m_ratio, -m_ratio, 0, m_doc.GetPageHeight(0) * m_ratio);
				page.RenderToBmp(bitmap, mat);
				float rect[] = new float[4];
				rect[0] = 100;
				rect[1] = 80;
				rect[2] = rect[0] + 100;
				rect[3] = rect[1] + 20;
				page.AddAnnotEditbox(mat, rect, 18, 0);
				mat.Destroy();
				page.Close();
				m_doc.Save();
			}

Do I need to create a bitmap and addAnnotBitmap to the page? Or is there another bitmap that I would use and clear? Thanks for your help.

no need to create Bitmap object to add FreeText annotation, like this:

	bitmap.eraseColor(0xFFFFFFFF);
	Page page = m_doc.GetPage(pageno);
	if( page != null )
	{
		Matrix mat = new Matrix(m_ratio, -m_ratio, 0, m_doc.GetPageHeight(0) * m_ratio);
		page.ObjsStart(bitmap, mat);
		float rect[] = new float[4];
		rect[0] = 100;
		rect[1] = 80;
		rect[2] = rect[0] + 100;
		rect[3] = rect[1] + 20;
		page.AddAnnotEditbox(mat, rect, 18, 0);
		mat.Destroy();
		page.Close();
		m_doc.Save();
	}
