I now have another PDF with the same problem, but this time from another customer.

It seems there no development in the rendering part of QuickPDF, so I have to find another supplier.

Any suggestions ???

As I suspected... Loading and re-saving made no difference. Even working with an uncompressed version of the file did not help.]]> Tue, 04 Apr 2006 15:05:20 +0000 http://www.quickpdf.org/forum/printing-problem_topic380_post1641.html#1641 <![CDATA[Printing problem : I have my doubts -I don&#039;t...]]> http://www.quickpdf.org/forum/printing-problem_topic380_post1640.html#1640 Author: swb1

I have my doubts - I don't think that the encoding of the image stream will change. I will try that nonetheless.

Hi!

What about (as a first workaround) to unencrypt the pdf and resave it with the iSED-library and then to render?

Best regards,
Ingo

Thankx

Now we at least may post this as a bug in the correct forum and maybe it will be fixed in the future - this is more than I could hope for with ised

Jan,

 

There is something about the image in your document that is not handled properly by the QuickPDF Library.

 

Quick PDF uses GDIplus to render images. When Quick PDF attempts to load the image stream in your PDF, the function call returns “Invalid Parameters” . I do not have adequate documentation on GDIplus to understand how or what parameters are supposed to be passed to the GDIpLoadImageFromStream function.

 

I suspect that your PDF is created with a newer specification of JBIG2Decode than currently is supported by the QuickPDF library. I do not (at this time) possess the resources to solve this.

 

Perhaps another member of this forum who has better GDIplus knowledge would like to take a swing at this. Or maybe you could create your documents using and older specification.

 

As it stands now QuickPDF will not render your PDF correctly.

 

Regards,

Hi Guys

I have tried all your hints - but with no luck :-(

I have sent the PDF file to swb1 - lets see what he can do with it.

I also had a similar problem, with a PDF file that was encryped with a password. The first page was blank but the rest showed OK.

Using "SetPassword" and "UnEncypt" fixed the problem.]]> Sun, 02 Apr 2006 22:23:04 +0000 http://www.quickpdf.org/forum/printing-problem_topic380_post1627.html#1627 <![CDATA[Printing problem : Jan, I had a similar problem...]]> http://www.quickpdf.org/forum/printing-problem_topic380_post1626.html#1626 Author: Frank

Jan,

I had a similar problem now, when I was using the function RenderPageToStream.
The first page I rendered, always happened to be blank. All following pages then were rendered correctly.
Perhaps this issue depends on how the QuickPDF library is used. In my trials I used the source code.

I revealed that, when I called the function SelectPage before the first call of RenderPageToStream, the first page also was rendered correctly.
It seems, that it doesn't matter, what number I enter for the SelectPage function, but it only matters that SelectPage is called before RenderPageToStream.

When I have more time, I will analyze this behaviour more thoroughly.

Maybe your problem is not caused by the first page being a large Image, but by the same problem I had now.
Try something like qp.SelectPage(0) before you print your file. I wonder if the workaround for my problem is a remedy for your problem also.

Frank
