I have a PDF that was built with Adobe Acrobat (i think version 7.x).

I downloaded the trial version of Quick PDF version 7.17 and I am using the DCUs for Delphi 7.

I wrote a simple routine to load a pdf and then try to render as an EMF.

1. The text on the emf looks horrible.

2. There is an image at the top of the pdf that is not coming out right either, it has streaks running through it.

I have tried various DPIs and also rendered as bmp, jpg, png and tiff.

All of those formats the text looks great but the image is still messed up.

I really need to be able to export as EMF.

Here is my sample code but I dont know how to attach the original pdf or the output emf.

Any help will be greatly appriciated.

procedure TForm1.Button1Click(Sender: TObject);
var
PDF: TQuickPDF0717;
begin
PDF := TQuickPDF0717.Create;
try
    PDF.UnlockKey(PDF_Unlock_Key);
    PDF.LoadFromFile('C:\Temp\Test.pdf') ;
    PDF.RenderPageToFile(300, 0, 3, 'C:\Temp\Test.emf') ;
finally
    PDF.Free;
end;
end;

Hi Wayne!

If you tried already various syntax alternatives
with no success then this case looks like a bug
or a not well developed functionality - Post it on
the official support page.

Cheers, Ingo

I have another question about the RenderPageToFile command:

If I use QuickPDF in a little testprogram everything is fine. If I include the code into our application, I have to set the DPI values about ten times higher to get the same result, and after several calls, the program crashes.

Of what depends the bitmap's number of pixels ? (additional to DPI setting)
