Hi,
did you try to debug what the GetPage() call does? I think it's much
easier than asking anyone else doing that for you.

I do not know, but I suppose (I think), that the first call reads the
page structure and caches it for later use. Kind of lazy reading. But
I neither debugged what the call does, nor read the sources. This is
just my idea.
Bye,
zyx

P.S.: Please pick one list alias and send only to that one. Your
message had been received twice here. Thanks.

[Podofo-users] PdfStream and PdfFilter documentation fixes

[Matthew Brincke]

Hi all,

I have attached a patch with clarifications, formatting
and typo fixes to PdfStream.h and PdfFilter.h (please
review them, if accepted, please apply). I only post this
late because I had problems with my Internet access, I'm sorry.

Best regards, mabriIndex: src/base/PdfStream.h

[Podofo-users] Reg: Support Required

[Sriram Gopalan -ERS, HCL Tech]

Hi,

We are using Podofo for inserting images into a PDF file.
It works as expected for most files but for some files we are facing issue:

The problem is when we use PdfDocument-getPage() after initializing an image, 
it takes huge time.
It takes time only for reading the first page after image initialization.

Please find the code snippet below:

PdfMemDocument *doc = new PdfMemDocument();
doc-Load(PDF_FILE);


PdfImage image(doc);
image.LoadFromJpeg(C:\\Users\\Public\\Pictures\\Sample Pictures\\desert.jpg);
page = doc-GetPage(1);
page = doc-GetPage(10);


Only the highlighted line take time. Whatever might be the page Number, the 
first use  of GetPage() takes time.

Request to share your support on the same.

Thanks  Rgds
Sriram K G
