For those creating PDF files directly from Access or from a PDF
creation tool (i.e., without using the A2K7 PDF Add-In), perhaps the
following solution for a vector ellipse will work until I come up with
something better.

Objective: Draw an ellipse centered at (X, Y) pts with eccentricity e
used to stretch a circle along the X-Axis using the existing brush
color, or (R,G,B) values if they are specified.

Although stretching out a circle is simpler than creating an ellipse
from scratch, it has a disadvantage that the width of the line also
stretches, making the boundary tenuous near the minor axis. That
might look O.K. for smaller ellipses or ones having only a slight
eccentricity (1 = perfectly round). I checked that the center of the
circle did not change when stretching by marking the center of the
original circle after the ellipse was created and the graphics
environment restored, but I didn't actually measure it on the printed
page, so it's possible that the origin moves when the circle is
stretched.

How I made the layout for importation into the PDFLayoutViewer
database:

'Begin code behind form
Private Sub cmdMakeFlatEllipse_Click()
Dim strOut As String
Dim strFileOut As String

strFileOut = "C:\FlatEllipseLayout.txt"
strOut = DrawFlatEllipse(0.5, 200, 350, 50, 1.35, 0.7, 0.3, 0.5)
Open strFileOut For Output As #1
Print #1, strOut
Close
MsgBox ("Done.")
End Sub
'End code behind form

A sample output PDF file (produced from A97) is available at:

https://files.oakland.edu/users/fort...latEllipse.pdf

I used the Landscape option that I recently added to my
PDFLayoutViewer database. The vector based curves look good even at a
6400% PDF zoom level. Perhaps I can come up with something better in
time. The fact that Bezier curves must be used to create ellipses
having constant line widths in PDF documents complicates their
creation. To create a circle using Bezier curves, I used a technique
found at:

Here is a sample of a PDF ellipse created from A97 using about 28
Bezier curves.

It should be possible to apply a coordinate transformation in order to
tilt the ellipse any amount and still have it be fairly smooth.

I worked some more on getting the PDF ellipses smoother, plus I'm
including the code I used to create the layout as input to the
PDFLayoutViewer (modified with a Landscape option):

https://files.oakland.edu/users/fort...ueEllipse2.pdf

Note that I specify the lengths of the major and minor axes instead of
using the eccentricity. It wouldn't be difficult to free the delta
angle from its current limitations.

Once a reasonable number of arcs is chosen, the main technique for
smoothing out the ellipse is to adjust the parameters L1 and L4, which
correspond to the distance of the Bezier control points from their
respective origin. Lengthening or shortening those distances seem to
tighten or loosen the control point's "draw" on the Bezier Curve. Too
much of either is not good. You can end up with "corners" along your
ellipse or "loops" if the lengths become too short or too long. I
stopped when I got the ellipse substantially smooth, but could have
gotten it smoother with more effort. Besides, at 0.2 line width it's
pretty easy to catch major flaws. It turns out I needed to be able to
create filled ellipses anyway in order to make a vector version of the
company's new logo to put on PDF reports.

Note: It turned out not to be necessary to get the "Alpha" Bezier
angles, so strAlphaBeta and it's code can be removed for the "Alpha"
case.
