In what way is the "quality poor" ?

I use a similar code with good quality faces but the origin of narrow
characters seems misplaced. I start with an existing font in AFont, and
a canvas ACanvas.

var
LogFont : TLogFont;

FontAngleD := FontAngleR * DegPerRad; // in deg
{make a font of this angle}
with LogFont do begin
FillChar(LogFont, sizeof(TLogFont), 0); {clear memory}
lfHeight := AFont.Height;
lfEscapement := trunc(FontAngleD * 10);
lfOrientation := lfEscapement; // should be same
lfWeight := FW_BOLD;
lfOutPrecision := OUT_TT_PRECIS;
lfFaceName := 'Arial';
ACanvas.Font.Handle := CreateFontIndirect(LogFont);
end; {with LogFont}

Yes, your code gives the same results. The quality depends on the typeface,
the weight and the size. Arial is better than Times Roman, bold is better
than normal, large letters come out better than small ones. When you have a
smallish font (say 10 pt) and place texts above each other with a rotation
interval of 5 degrees you see immediately that letter spacing and alignment
are poor.
But if this is the best there is, it will have to do.
