This method is useful if you want to highlight a word on the page or if you want to cover some words with a colored rectangle.

You can check the following conditions to detect whether an extracted word is visible on the page:

• Layer should be absent or visible.
• RenderingMode should not be equal to NeitherFillNorStroke or AddToPath.
• Bounds should fit into the corresponding ClipRegion. You can use IsVisible(PdfRectangle) method for this check.
• If you know the background color of the page, then you may check that the word color is different. You can use Brush and/or Pen properties depending on the RenderingMode.
