How I can interpret ROP3 values?

For example, I have ROP3=67

This is SPDSanaxn (S = Source, P = Paint, D = Destination, a = AND, n = NOT, x = XOR)

How interpret this?


The ROP3 values in PCL6 are exactly the same as those defined in PCL5 (and, originally, apparently in some Microsoft documentation).

The only difference that I can think of is that 'Paint' is sometimes referred to as 'Texture' or 'Pattern'.

The values are shown in 'Reverse Polish Notation'.

So, for example, PDSoxn means:
NOT (paint XOR (source OR destination))

'destination' is what is already on the paper (and also what will be the result of the operation);
'source' is the shape of the object to be added;
'paint' is the pattern (texture) to be applied through the 'source'
I've never really been that familiar with RPN, so I'm not sure how your ROP3=67 value should be interpreted (although, as it is a stack-based mechanism, it should be fairly easy to work out).

Perhaps some-one else who is familiar with RPN, or has more time to think about it, can oblige?
