This property determines whether certain tags in
HTML are noted so that their location can be determined at a later date.
After adding your web pages you can retrieve
information about the items on the PDF page using the GetTagIDs and
the GetTagRects
methods.
Note that only HTML elements which have an actual visual representation in
the final output will be tagged. For example, a simple
<form> element may not be
tagged because it does not have a visual representation.
All elements of style 'abcpdf-tag-visible: true' will be tagged. For example:
<p id="p1" style="abcpdf-tag-visible: true">Gallia est omnis divisa in
partes tres.<p>
For the Gecko engine, having a visual representation is not enough. The
element must be a display item, which means that there is something to display
for the element. Inner contents, such as text and inner elements, are children
of the element and are not the element itself. This is important for layout-only
elements such as <p>, <div>, and <span>; and style-only elements
such as <em>, <strong>, and <font>. Border, outline, etc. are some of
the things that make a layout/style-only element a display item:
<p id="p1" style="abcpdf-tag-visible: true; border: 1px solid
transparent">Gallia est omnis divisa in partes tres.<p>
For the Gecko engine, you can use the CSS class 'abcpdf-tag-visible'
instead of the CSS style 'abcpdf-tag-visible: true' (even if the CSS class is not defined),
but it is deprecated. See UseCSSClassToAddTags in
Registry Keys.
<p id="p1" class="abcpdf-tag-visible" style="border: 1px solid
transparent">Gallia est omnis divisa in partes tres.<p>
