Text is fainter when it has watermark behind it
Posted: Wed Apr 25, 2012 3:19 pm
I've noticed that the text in a document that is 'on top of' a watermark appears lighter/fainter than neighbouring text in the same font which is not on the watermark.
The watermark is added using this Delphi code:
Is this the intended behaviour, or is there a setting that I can change to affect this?
Secondly, according to PDFX4DRV_API.pdf, page 49, for dwOpacity "Value must be in the range of 0 (fully transparent) to 100 (fully opaque)."
However, the code above and some examples on this forum seem to support a range of 0 to 255
Is this just another mistake in the documentation?
