Appending pages to a pdf

1. offizieller Beitrag

    In order to append new pages to an existing pdf file, i use the property InputfileMode = pwAppendToInput but the size of the resulting file grows by two for each page that i append to the output file. Is this a bug or somebody can explain me the correct way of how to append a new page to an existing file.

    Thanks in advance

    Hi,

    From DLL version 2.5.3.3 there is the problem in the size of appended files.
    (used not to be there in 2.5.0.0 and before that version)

    Delphi 5 code I used to test:

    WPDF_Start('ID Data','**deleted for security reasons**');
    wppdfprinter1.filename:='c:\testsize.pdf';
    wppdfprinter1.inputfile:='c:\testsize.pdf';
    wppdfprinter1.InputfileMode:=pwAppendtoInput;

    wppdfprinter1.BeginDoc;
    wppdfprinter1.StartPage( Round( 21/2.54*res), Round(29.7/2.54*res), res,
    res, 0);
    wppdfprinter1.Canvas.TextOut(100,100,'AAAAAAAAAAAAAAAAAAA');
    wppdfprinter1.EndPage;
    wppdfprinter1.EndDoc;

    The size of the file approximately doubles every time you append one page.

    1 page 4kB,
    2 pages 7kB
    3 pages 17kB
    4 pages 33kB
    5 pages 67kB
    6 pages 133kB and so on.

    I also tried to have the filename and input file different, and then
    swap them every time I run the program but the same happens here.

    This was not the case with DLL version 2.5.0.0

    What has changed, or what am I doing wrong?

    Cheers,

    Hans
