Hi,

you can delete annotations using [PDFAnnot removeFromPage] method, and iterate on the whole pdf with something like:

for (int i = 0; i < [m_doc pageCount]; i++) {
        PDFPage *page = [m_doc page:i];
        
        int count = [page annotCount];
        if (count > 0) {
            for (int c = (count - 1); c >= 0; c--) {
                PDFAnnot *annot = [page annotAtIndex:c];
                [annot removeFromPage];
            }
        }
    }

To change the thumbnail background color you have to set the backgroundColor of PDFThumbView in vOpen method.
