Raster Operations
◄Up► ◄Next► ◄Previous►
────────────────────────────────────────────────────────────────────────────
This appendix provides a table of raster operation codes and their
definitions. The raster operation codes define the ways in which BitBlt
combines the bits in a source bitmap with the bits in a brush or pattern
bitmap and the bits in the destination bitmap.
The operands used in the operations are as follows:
S Source bitmap
P Paintbrush or Pattern currently selected
D Destination bitmap
The Boolean operators used in these operations are as follows:
o Bitwise OR
x Bitwise Exclusive OR
a Bitwise AND
n Bitwise NOT (invert)
The operations are presented here in reverse Polish notation. For example,
the operation DPSoo performs a logical "OR" on the source and pattern and,
then, performs another logical "OR" with the destination. The result is then
stored in the destination.
Notice that there are alternate spellings of the same function. Therefore,
although a particular spelling may not be in the list, an equivalent form
will be. For example, "DPoSo" is a form equivalent to "DPSoo."
In general, the functions are spelled in such a way that it is easiest to
read them outward from the place at which they change from upper to lower
case. For example, PSDPSanaxx may be read as follows:
PSD %PSa% naxx: `and' source with pattern.
PSDPSa %n% axx: complement result.
PS %D% PSan %a% xx: `and' with destination.
P %S% PDPSana %x% x: `xor' with source.
%P% SDPSanax %x%: `xor' with pattern.
The following is another, more complex example: (This expansion is of ROP
0017h from the table below.)
The ROP: %SSPxDSxaxn%
The expansion:
S %SPx% DSxaxn: `xor' source and pattern.
SSPx %DSx% axn: `xor' destination and source.
S [%SPx%][%DSx%]%a% xn: `and' the bracketed items.
%S% SPxDSxa %x% n: `xor' result of last step with source.
SSPxDSxax %n%: complement result, and put into destination.
The Operation Codes
Each raster operation code is a 32-bit integer value; the high-order WORD of
which is a Boolean operation index, and the low-order WORD of which is the
operation code. The 16-bit operation index is a zero-extended 8-bit value
that represents the result of the Boolean operation on predefined pattern
(P), source (S), and destination (D) values. For example, the operation
indices for the PSo, PSon, and DPSoo operations are as follows:
P S D PSo PSon DPSoo Arbitrary function
───────────────────────────────────────────────────────────────────────────
0 0 0 0 1 0 1
0 0 1 0 1 1 0
0 1 0 1 0 1 0
0 1 1 1 0 1 1
1 0 0 1 0 1 1
1 0 1 1 0 1 0
1 1 0 1 0 1 1
1 1 1 1 0 1 0
Hex FC 03 FE 59
Opcode:
Any Boolean function can be represented by the string of 1's and 0's on the
right side of such a table. In this case, PSon is the string 00000011 (read
from the bottom up), which is hexadecimal 03. (Recall that this is then
zero-extended to the left: 0x0003.) Notice the PSon function in line 4 of
the table.
In general, any arbitrary function such as the one on the far right above,
has a unique hexadecimal number associated with it (in this case, 0x59). By
looking in the table, one then finds the appropriate Rop (in this case,
0x00590609) and a function that evaluates it (DPSnox).
The first four digits of each opcode determine the location of the raster
operation in the table: the PSo operation is in line 252 (hex FC) of the
table, DPSoo is in line 254 (hex FE), and so on.
The most commonly used Rops have been given special names. Therefore, it is
recommended that programs define the common name to be the Rop number and,
then, use the common name throughout, to be consistent with the current "no
magic numbers" style.

The following is a list of the Boolean functions in hexadecimal and reverse
Polish notation, along with the Hex Rop and common name.
