hi,

Delphi : I access a PDF file with "DAOpenFile" . I want to add an image to this PDF file then save it with another name with "DASaveAsFile". I wrote the following code but it creates a PDF file with an empty page with the image.

Here is my code:

var
QuickPDF: TDebenuPDFLibrary;
FileHandle : Integer;
begin
try
QuickPDF := TDebenuPDFLibrary.Create ;
QuickPDF.UnlockKey(edtLicenseKey.Text) ;
FileHandle := QuickPDF.DAOpenFile('D:\MyPDF_file.pdf', '');

QuickPDF.AddImageFromFile('D:\Myimage.png',2);

QuickPDF.DrawImage(380, 200, 120, 120);

QuickPDF.DASaveAsFile( FileHandle , 'D:\PDF_With_image.pdf' );

finally
QuickPDF.Free;
end;

//---------------------

how to do please?

thanks

Hi Amelie :)

Don't mix ... NEVER mix DA-functions with non-DA-functions - This won't work.

Take the normal open- and the normal save-function and it will work as expected.

Cheers,

Ingo

Hi Ingo,

thank you for help.

I have a big file of 600mb, when I open it with ''LoadFromFile'', my application consumes a lot of resources, but, if I open this file with 'DAOpenFile', there is no consumption of resources.

- if I use 'DAOpenFile' + 'SaveToFile', the application creates an empty page with the image.

- if I use 'LoadFromFile' + 'SaveToFile', it's ok, but a lot of memory consumption.

How to solve this problem please?

THANKS

There's nothing to solve ;-)

Don't mix DA- with non-DA-functions.

Try the "normal" functions and do a complete refresh after the call.

Provided that your program does not crash on 'out of memory', there should be no problem with using the 'non-DA' functions, other that it being slower to process your very large file. If the other parts of your program give it a very big memory requirement, and the process memory exceeds 2GB, then you can try increasing this by adding {$SETPEFLAGS IMAGE_FILE_LARGE_ADDRESS_AWARE} immediately above the 'begin' in your Delphi DPR file. Or of course you could also build it as a 64-bit process, which might also speed it up a little.
