# DefaultOverlayStartTag

The default value to use for the StartTag parameter in the View or GetLink action when highlighting PDF2-rendered documents, where the View component renders the PDF as a transparent text layer overlaid on an image of the page.

NOTE: You can enable the PDF2 reader by editing the `formats_e.ini` file to set `200=pdf2sr`.

By default, View uses a translucent background color, so that the underlying text in the image is visible, and highlighted. Set `DefaultOverlayStartTag` and DefaultOverlayEndTag to modify this highlighting behavior.

To highlight the underlying image while keeping the text itself invisible, you can set `DefaultOverlayStartTag` to a translucent background color (by using eight-digit hex, or the rgba or hsla functions with partial opacity). To highlight with text effects, set a solid color without transparency for both the text and the background, to make the text layer visible while obscuring the underlying image.

You can override the value of `DefaultOverlayStartTag` by setting StartTag in the View or GetLink action.
