Gets an array of the locations of tagged visible items.

[C#]
virtual XRect[] GetTagRects(int id)

[Visual Basic]
Overridable Function GetTagRects(id As Integer) As XRect()

Use this method to retrieve the locations of tagged visible items. The locations are to be used with Doc.Transform being identity.

To use this method you need to enable the tagging functionality. See the AddTags property for details.

This function takes an ID obtained from a call to Doc.AddImageUrl, Doc.AddImageHtml or Doc.AddImageToChain and returns the locations of any items which are visible on the PDF page as a result of that call.

The locations match up directly on a one-to-one basis with the IDs returned by the GetTagIDs function.

The following example shows the effect that this parameter has on HTML rendering.

[C#]
Doc theDoc = new Doc();
theDoc.Rect.Inset(100, 100);
theDoc.Rect.Top = 700;
// Tag elements with style 'abcpdf-tag-visible' 'true'
theDoc.HtmlOptions.AddTags = true;
int id = theDoc.AddImageHtml("<FONT id=\"p1\" style=\"abcpdf-tag-visible: true; font-size: 72pt\">Gallia est omnis divisa in partes tres.</FONT>");
// Frame location of the tagged element
XRect[] tagRects = theDoc.HtmlOptions.GetTagRects(id);
foreach (XRect theRect in tagRects) {
  theDoc.Rect.String = theRect.ToString();
  theDoc.FrameRect();
}
// Output tag ID
string[] tagIds = theDoc.HtmlOptions.GetTagIDs(id);
theDoc.Rect.String = theDoc.MediaBox.String;
theDoc.Rect.Inset(20, 20);
theDoc.FontSize = 64;
theDoc.Color.String = "255 0 0";
theDoc.AddText("Tag ID \"" + tagIds[0] +"\":") ;
// Save the document
theDoc.Save(Server.MapPath("HtmlOptionsGetTagRects.pdf"));
theDoc.Clear();

Dim theDoc As Doc = New Doc()
theDoc.Rect.Inset(100, 100)
