ditte, I cannot follow you
Please send a clear and complete description of your problem together with a PDF sample to support(at)quickpdf.org
 
In case this problem is caused by program logic please attach a small demo program as well. You can write your demo in Delphi, C++, VB or any .Net language you want.
 
Best regards, Marian

Hi Marian,

thanks for your detailed representation.
Before I found quickpdf/pdpicture I´ve tested, I think more as 10 other similar products. I´m pleased with the tool. I think not, that the linearized pdf is  the solution for my dilemma.
I get my pdf´s on many ways. (email from other, self generated by CrystalReportsXI, printengine and over the scanner ScanScnap S500 from Fujitsu Simens). The last seams the proble to be. All incomming post will be scanned and pdf documents will be created. This will archived over other program. An this document make the trouble.  (if I  load these documents all the effects will be, that I´m had described. I don´t know how can I test this files to know what is wrong.

Is there a program that can test pdf files?

Regards Dittmar

ditte, the QuickPDF does not support linearized PDF's.
 
The problem is caused by the current implementation of PDF parsing engine. The QuickPDF loads the whole pdf in memory, scans for trailer (end of PDF), read the xref section and then jumps to the page location.
 
From what I understand to support linearized document the reader should read sequentialy the document, detect stream sections and render asynchroneusly when enough information is available.
 
This means that someone must write:
1. a new PDF parser (not really a problem)
2. a ThreadSafe rendering engine which can render images while document is loading.
 
This is not really a big implementation problem. But this is in now way something that it can be done for free.
 
For more details feel free to contact me per email:
support(at)quickpdf.org or quickpdf(at)gmx.net.

So you're using QuickPDF, not Adobe Reader, to render and view the PDFs. Then linearizing won't help. QuickPDF is considerably slower than Adobe Reader at rendering. You may want to consider a faster alternative.

Hi Marian,
sorry at first, I don´t know it.
Now to the problem.
I´ve tested the APStripsFiles and converting my files to linearize (Fast Web View).
But it don´t helps further. There are no visible better performance.
It seems not to be the problem.
I´ve a black/white document (24kB) it needs ca. 4 sec to loading
(PFU ScanSnap Manager 4.0.11, Adope PDF Scan Library 2.1, PDF Version 1.3)
I see in the Process Explorer (sysinternals) following memory transactions.
Working set before: 167.096K
Click of lading ->263.565K and back to  218.556 ( very much).
A other pdf document (I get it as offering from a distributor) It is in color(14kB)
( PScript.dll Version5.2,Acrobat Distiller 6.0(Windows) PDF Version: 1.4)
Working set before: 167.396K
Click of lading ->168.208 K
(My environment 1000Mbit Network, Server PentiiumIV, 2 GB Memory, W2003, Workstation Core2Duo, 2,4 GHz, 2 GB Memory)
I´m using the isedquickpdf(5.22.0.119) inside the gdpicturepro (3.03.0001).

Regards Dittmar

And, of course, Ghostscript also allows you to linearize PDF files.

Dittmar,
I have investigated a little bit the theory of this feature. I understand now why it may be so important. I am so surprized that nobody mentioned it before.
 
Best regards, Marian

Appligent has a free tool (APStripFiles) that comes with a nice bonus, the ability to linearize (Fast Web View) PDFs:

Hi there, I know that I have long hair but I am still proud to be a man and not a women Smile
 
Dittmar, in case you want to get in contact with me you can reach me here or at support(at)quickpdf.org. Just because I don't answer it does not mean that I am not online, it just means that I am answering direct calls or some hard issues.
 
For your information: handling linearized PDF files is not on my dev list. Although I had no interest in this feature I am paying a lot of attention to performance problems. In case you have some performance issue fill free to write me about your problems.
 
best regards, Marian

Hi Ingo,

sorry now I´ve understand what you mean.
Marian was the correct for new fetures.
An what you´ve done is also intersting.
But what I like to do is only to show simple pdf documents. They aren´t very big. But if you scroll throught a table the pdf (100 kb) use in the memory for shortly time 20 MB and the most of the cpu capacity. The same document as web optimized only 2 MB.

Regards Dittmar
