in demo project:
single tapped on the markup annotation, and then click remove button.
as souce codes, to add markup Annotation(in PDFView.vSetSelMarkup):

if( m_pages[pcur].SetSelMarkup(type) )
{
vRenderSync(m_pages[pcur]);
Page page = m_pages[pcur].GetPage();
int markup_index = page.GetAnnot(page.GetAnnotCount()-1);
//....
return true;
}

Page page = m_pages[pcur].GetPage();
if( page != null )
{
Annotation annot = page.GetAnnot(annot_index);
annot.RemoveFromPage();

Hi,

I do not understand this response very well. I understand that the highlights are treated as markups, but if what I want is to clear just part of a highlight, how can I do it?. Suppose I have this text

Lorem ipsum ad his scripta blandit partiendo, eum fastidii accumsan euripidis in, eum liber hendrerit an

And I want to clear just part of the highlight in order to get something like this

Lorem ipsum ad his scripta blandit partiendo, eum fastidii accumsan euripidis in, eum liber hendrerit an

On the other hand, how can I get all the markups for a given selection?

Thanks in advance!
