space, so no transformation is needed.
iTargetPage   Specifies the page number of the destination page within the
document.
xtfvTarget   Specifies the x-coordinate of the target location on the destination
page. The unit of measure for this value is points.
ytfvTarget   Specifies the y-coordinate of the target location on the destination
page. The unit of measure for this value is points.
dytfTargetPage   The height of the destination page in points. The offset specified
by the ytfvTarget member is relative to the upper-left corner of the page.
However, some fixed-format types use a coordinate system that is relative to the
bottom-left corner of the page. For these types of documents, the page height is
required to convert the offset.
The DocExComment_ColorInfo structure specifies color-state information for the EMF.
For more information about this structure, see the section Extended Color Support.
C++
The members of the DocExComment_ColorInfo structure are as follows:
ident   Specifies the constant value, msodocexsignature, which identifies this EMF
comment as containing semantic information.
iComment   Specifies the MSODOCEXCOMMENT value,
msodocexcommentColorInfo.
clr   Specifies a color ID that represents a current color state in the EMF.
fForeColor   Specifies whether the color ID in the clr member represents a
foreground color or a background color. If this member has a value of true, the

struct DocExComment_ColorInfo
{
    DWORD ident {};
    DWORD iComment {};
    COLORREF clr { 0 };
    BOOL fForeColor {};
};
