Resolution 2nd try

I want to print a 300 dpi pdf file using wpdf 2.0.
so I tried this code:

with WPRichText1.Header do
               begin
                    // the page width and height are only internaly skipped when
                    // printing in landscape
                    if Landscape then
                    begin
                    end
                    else
                    begin
                         PDFPrinter.StartPage(MulDiv(PageWidth, 300, 1440),
                                              MulDiv(PageHeight, 300, 1440),
                                              300, 300, 0);
                         OutRect := Rect(0, 0, MulDiv(PageWidth, 300, 1440), MulDiv(PageHeight, 300, 1440));
                    end;


                    WPRichText1.PrintPageOnCanvas(PDFPrinter.Canvas, outRect, counter, [ppmUseBorders], 100);// MulDiv(100, 600, 96)); //MulDiv(100, 1440, 300));
                    PDFPrinter.EndPage;
               end;

The page size is correct (DinA4) but the printed page is somewhat shrinked (when referencing a 600 dpi Printer (used in Reference DC))

Also the Canvas to print does not have 300 dpi as promised in the description of StartPage, it has 600 or 96 dpi (depending on the referenced
printer property).

Do I miss something or is there something wrong with wpdf?

We work on Version 4.

So as far as I can see is that StartPage using these parameters should
create a 300dpi output (and pherhaps it does so). but my main problem
ist that the PrintPageOnCanvas produces a havily shrinked output
which must be zoomed using the zoom parameter (the right value is
the one commented out) and I don't think that this is correct. Also if
Zooming in such a way I get the same results as printing quality as with screen resolution.

so any idea?

Julian, pherhaps you can provide me some sample code which
creates a 300 dpi pdf.

By now I have the feeling that if I use the code I provided here I get a 300
dpi File but WPRichedit prints it with the screen resolution and I have to zoom
it to the 300 dpi (with the zoom parameter in PrintPageOnCanvas). So the
visible result is the same for 300 dpi documents as for 96 dpi documents

kind regards
