I need to rewrite some X stuff for ms-windows ( WIN3 ), know nothing
about ms-windows, and alas! there is no O'Reilly book for it --
just this "SDK Reference".

I would like to find a reasonably small win3 program that uses
ms-windows bitmaps as the subject of drawing routines and, later on,
uses the bitmaps for writing to a window; said program to serve me
as an example.

For a recent version of how this technique is done in the X Window
System, see comp.sources.misc,
v34i022:  xvertext - painting vertical text in an X Window, Part01/01

I have RTFMed, and believe all this is in TFM, but either the manual
is poorly organized or my brain is too feeble; in either case, I
feel the need for an example to make things clear.

There must be one in simtel20, but it isn't at all obvious to me
which one I want.

( I found and examined ntxlib.zip, but all such things are
unimplemented there, nor are there any clues as to how it would be
done. )

I have asked the Usenet Oracle, but He doesn't know, either :-)



The remainder of this message is merely a clarification of what I
need to do, and how much I've already figured out.

In stage one, drawing to the pixmaps, the X code I am working with
creates a pixmap of depth 1, and uses such calls as XDrawSegments,
XDrawRectangle, XFillPolygon to draw into the pixmap.

    In ms-windows, drawing calls do not take a "Drawable" as a
    parameter. This appears to be in some manner controlled by the
    DC. Exactly what I need to call to set this up, I do not know.

In stage 2, using the pixmaps, the X code calls XSetStipple()
XSetFillStyle( ... FillStippled : FillOpaqueStippled ),
XSetTSOrigin(), and XFillRectangle() in order to draw the desired
shape. By drawing the pixmap in this roundabout manner, two things
are accomplished: (a) whatever else is there is not disturbed; and
(b) the color is independent of what was done in stage 1.

    In ms-windows, this whole scheme is impossible. It seems that
    the msw call corresponding to XSetStipple() would be
    CreatePatternBrush(), but the size of the pattern
    must be 8 by 8!!

    I think that the correct msw way to do this is with bitBlt(),
    using just the right "rop2" code...
