Square images in render

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   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:

And this is what it's supposed to be:

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
	Cheers, 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. Edited by Adz - 02 May 16 at 9:12AM

	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);
	Cheers, Ingo

	Hi Ingo, Actually the problem persist on all of the pages in my sample pdf file. Thank you for your help.
