Ryan, some of my basic "un known facts " about the spec relating to
SPRM's.
A SPRM as represented by me will look like..
OpCode
length of Param (for var length Param)
Parameter(fixed or Var length)
Size in bytes
2
1 or 2(for a special SPRM )
1 or 2 or 3 or n, (n can be > 256)
Offset in bytes
0
2
2 or 3
In the Sprm bits eplanation table, I could not get where
1. ispmd is used (0-8)
2. fspec is used (9).
In the SPRM details table,
Name
sprm
Property Modified
Parameter
Parameter size
Are they checking for the full OpCode value for the field "sprm".
Why have you used, short operand = (short)(sprm & 0x1ff); to pass this to the
DoXXXOperation().
Cant we directly check the "sprm" for the respective Values like if(sprm
== 0x4600).
In the eplanation given for "sprmPlncLvl" it says The sprm is three bytes long and
consists of the sprm code and a one byte
two's complement value. Are they refering this to just the Parameter(3 byte case). Or
2 byte Opcopde + 1 byte Parameter.
If its latter, then as per spec we have to take the LSByte of the "param"
we r passing to the function & check its sign bit & so on..
If its Former then we hv to check the sign bit of "param" itself..
Am I right?????
NB: If MS could have given atleastt a better Documentation which is
Clear,Readable, Understandable and in a well arranged manner, it would
have been more easier for me!!. Now just for implementing a SPRM I have to
search its info scattered throughout the entire Document, still not sure
If I missed something.
Thanks & Regards

Praveen,
I changed StyleDescription so that the istd is now a part of _papx as well
as being stored in _istd for quick access.
