Hi,

I am working on a project using Delphi and QuickPDF0911 and came across a problem wherein the rendered document contains square images instead of texts, numbers or parentheses.

Here is what it looks like:
Bad render

And this is what it's supposed to be:
Correct render

What causes this and how can I render it properly?

Any help is greatly appreciated. Thank you.

Hi Adz,

12.12 is the actual version and the renderer is always a main area for enhancements.

So i can only advice to check the new (test-)version regarding your issue.

You've posted the sample and so i can only say that the renderer from 9.11 won't render your sample in a proper way.

Try the extraction with all font data... will all text content be extracted? ...any specialities regarding the strange letter rendering?

If you can upload your sample anywhere online i can check version 12.11 to see if rendering is better.

Cheers and welcome here,

Ingo

Hi Ingo,

I haven't tried extracting data from it but I think it's ok as I can see the whole correct content of the pdf file using different viewers (Adobe, Foxit). As for any specialties with the letters, I see none of it. ~~Please have a look at this pdf sample:~~

Can you also check in your 9.11 if we have the same rendering problem? I may have overlooked something. Thank you for your help.

Hi Adz,

seems to me that 9.11 has probs but i don't want to proof it...

With my preview function i've taken your pdf and had a look on the relevant page 29 - it's absolutely okay.

My code is made with QuickPDF 10.14.

If you like the library you should buy the update...

Here's a code snippet from the routine (Delphi XE):

QP.LoadFromFile(Edit1.Text, ''); //fneu);

If ( QP.EncryptionStatus > 0 ) Then

QP.Decrypt;

pmax := QP.PageCount;

if gv_lang = 'E' then

Form4.Label1.Caption := '1 from ' + IntToStr(pmax)

else

Form4.Label1.Caption := '1 von ' + IntToStr(pmax);

QP.CombineContentStreams;

// QP.RenderDocumentToFile(72,1,1,1,tpath + ExtractFileName(Edit1.Text) + '.jpg',1,0);

test_stream := TMemoryStream.Create;

if ( zoom = 0 ) then

zoom := 72;

QP.RenderPageToStream(zoom,1,1,test_stream);
