Another,

 

I believe the sGrayPrimary is used to specify the base color for
monochrome printing where the base color is black.  The specification
states that the sGrayPrimary replaces the white value.   I believe the
sGrayPrimary replaces the Black value; that is monochrome printing goes
from a color-to-white versus a color-to-black.

 

What is your understanding?  Or have I misunderstood the meaning and use
of this value?

One more question.

 

There are two "box sizes"; the Bounding Box and the Image Box.  There is
section for the Image Box but not the Bounding Box.  Can you explain the
difference between the two boxes.

Second question:

 

For "CutMedia", the specification state to use the "WhenEnum".  All of
the WhenEnum are "after" events.  I remember a discussion of "cutting a
page before".  So, are there any other WhenEnum values that should be
added.

Michael,

 

I finally got back to updating my routines for PWG Raster and had a
question.

 

1.	For ColorSpaceEnum

	a.	Can you confirm that the value 1 == Device RGB was
removed for the new version. Can you remind me why?

 

 

Glen
