Remarks

Image over text (or overlay) is used when creating a searchable PDF document that is required to look the same as the original. When overlay is used, the PDF creator uses a raster image of the original file and saves it over the entire PDF page as an overlay. When opening the resulting document in a PDF viewer, you can still search the text underneath the overlay image and still maintain the look of the original document.

When loading a page from a PDF document that was created with this feature, RasterCodecs will automatically render the overlay raster image on top of all other content of the page. If this is not desired, set the value of DropImageOverText to false.

DropImageOverText has no effect on pages that do not have an overlay.

Refer to PDFDocumentOptions.ImageOverText on how to create PDF documents with an overlay in LEADTOOLS, and to PDFDocument.GetContentType on how to detect if a page in a PDF file contains an overlay.
