Hii Radaee support.

I have been integrating the RadaeePDF in my project and i have some queries about ink annotations and thumbnail view.

1. How to clear the ink annotation from current page ?
2. How to clear annotations from entire PDF ?
3. Can we zoom in and out while using Pen ?
4. How to change the color of current page in thumbnailView?

Thanks

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.

Hii, thanks for the reply.

i applied your solution but it changed the background color of the thumbnail views.
I need to change the overlay color of the current thumbnail.

Please look at the attachment below.

Thanks.

Sorry, my fault. To change the selected thumb color you have to set the g_sel_color parameter in APP_Init method of PDFVGlobal.

If you enable ink mode, you cannot zoom or move because the scroll is blocked to allow the ink drawing.
