Bounding rectangle of a page was created by alexander.gustke

Hello,

how do i get the bounding rectangle of a visible page. Below my visible page is blank space and i need to determine how much is it (parentHeigth - pageHeight). I need this information to crop my visible bounding boxes (of the annotations) if i am going to shift them to the borders.

Thanks

Which version are you using, and which view mode?

i managed it by myself - thank you:

Code:

private float[] getBoundingRectangle() {
        int[] l = new int[2];

        getLocationOnScreen(l);
        PDFVPage pdfvPage = pdfView.vGetPage(currentPageNo);

        PDFView.PDFPos upLeft = pdfView.vGetPos(0, 0);

        int x = (int) (pdfView.vGetScale() * upLeft.x);
        int y = (int) (pdfView.vGetScale() * upLeft.y);

        int w = pdfvPage.GetWidth();
        int h = pdfvPage.GetHeight();

        return new float[]{-x, -(h - y), w - x, y};
    }

to get bounding box on screen:
PDFVPage vpage = PDFView.vGetPage(pageno);
int left = vpage.GetVX(PDFView.vGetX());
int top = vpage.GetVY(PDFView.vGetY());
int width = vpage.GetWidth();
int height = vpage.GetHeight();
