We are facing the very same problem:

Creating a protected PDF makes the information fields (Title, Author, Creator, Subject) unreadable when opening the PDF in Adobe Reader (or any other PDF viewer like Foxit Reader, even Google Chrome).

This used to work in past versions (can't tell which one; but I think this bug was introduced lately).

I've created an issue ticket on Github:
https://github.com/synopse/SynPDF/issues/32

Hopefully @ab will fix this as soon as possible.

Many thanks in advanve,
Achim

I use V1.18 with my enhanced clipping processing patch (EMR_EXTSELECTCLIPRGN; this patch was first accepted but later removed from SynPDF.pas). My local fork still contains this enhancements because some of the images I need to put into PDF include non-rectangular clipping areas -- but not the failed logo image. Besides of that I use the up-to-date code.

But I think it does not matter: The very same executable on my computer creates good-looking JPEG files, on the customers computer the JPEG is bad. Did you had a look at the example image?

There is no error message;

GdipTest('logo.jpg');

just completes.

Today I updated my local copy of SynPDF to the latest trunk version, mostly to get the PDF/A fix; but also to find out that my ExtSelectClipRgn() code was reverted in SVN revision 150.

My code was able to handle non-rectangular clipping areas by interpreting the Region arrays from Windows. Now the old code is active again, which can handle a single rectangle clipping area only. And I have the feeling that even this simple code is wrong, because Data.rcBounds is never used.

I've created a local branch and merged my code back into SynPDF.pas; with some small adjustments as mentioned where by MtwStark: Test for iMode == RGN_COPY. Now everything works fine, again.

AB, can you please dig into your version control software to find out if there was a specific bug, which lead to reverting my enhancements?!

TIA
Achim

BTW:
What would be needed to support PDF/A-3 with attachments (ZUGFeRD, an ugly german acronym for embedding invoice data as XML into PDF documents): http://www.ferd-net.de/front_content.php?idcat=231

Hello ab,

I've modified the function ENumFontsProcW as following:

"var TextMetric" changed from TTextMetric to TNewTextMetric as described in MSDN documentation:
http://msdn.microsoft.com/en-us/library … 85%29.aspx

Now I can test TextMetric.ntmFlags for OpenType fonts.
With that new modified code, the "Myriad Pro" font gets embedded into the PDF file.

However, the PDF file size increases from 5 KB (not embedded) to 180 KB (EmbeddedWholeTTF = False) and up to 510 KB (EmbeddedWholeTTF = True), but the OpenType font file is only 94 KB. I don't know why the PDF gets that large. And I don't have any tools to analyze the PDF files.

Here are my changes:

const
  NTM_PS_OPENTYPE = (1 shl 17);  // Bit 17: PostScript OpenType font
  NTM_TT_OPENTYPE = (1 shl 18);  // Bit 18: TrueType OpenType font

function EnumFontsProcW(var LogFont: TLogFontW; var TextMetric: TNewTextMetric;
  FontType: Integer; var List: TRawUTF8DynArray): Integer; stdcall;
// we enumerate all available fonts, whatever the charset is, because
// we may won't enumerate Arial or Times New Roman if current FCharSet is
// chinese e.g.
var Temp: RawUTF8;
begin
  with LogFont do
    if (   (FontType=TRUETYPE_FONTTYPE) 
        or ((TextMetric.ntmFlags and NTM_PS_OPENTYPE) <> 0) // <<< added
        or ((TextMetric.ntmFlags and NTM_TT_OPENTYPE) <> 0) // <<< added
    )
    and (lfFaceName[0]<>'@')
    then begin
      Temp := RawUnicodeToUtf8(lfFaceName,StrLenW(lfFaceName));
      if (pointer(List)=nil) or (List[high(List)]<>Temp) then
        AddRawUTF8(List,Temp,true,true);
    end;
  Result := 1;
end;

Nevertheless I will submit a feature request.

Regards,
Achim

Sorry, copy & paste error :-(
The new code is indeed using

NormalizeRect(result);

but that doesn't explain why the old code works fine, while the new code doesn't.

Any ideas how to solve that problem?

Hello AB,

I'll will provide some EMF files for testing soon.
