hi all
so i created some text in PDPageContentStream making it look like a
watermark.
However, i could not find any method that will make it somehow flatten to
the document so it will not be selectable.
Is this possible?
If so, which method or class should i be looking at?
The simplest would be to create an transparent ARGB image and draw your
watermark there and then draw this image into the PDF.
Another idea, which I haven't tested so it's a risk of time loss, would
be to draw the text in rendering mode 7 (RenderingMode.NEITHER_CLIP),
this will draw nothing but add the path of your glyphs to the clipping
region. Then draw a huge rectangle in some color on the whole page. This
will then draw the text as a shape. But I don't know if this will create
the watermark effect.
