As long as we know where we’re heading and can help to speedup things it’s fine. Now working on removing it from PdfStream, I’ll post a diff before committing. One more thing, I used to write things like: #if defined(pdf_long) PoDoFo::pdf_long mlen = 0; #else long mlen = 0; #endif stream->GetCopy(&mbuffer, &mlen); that allowed me to build code against 0.7.0 distribution as trunk as well (pdf_long has been introduced without version increment afaik) and I’m now wondering if it wouldn’t be the occasion to denote trunk with such a version number you proposed some times back: 0.7.99. -- Pierre Marchand -- ___ Podofo-users mailing list Podofo-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/podofo-users

Going further I see there are rather more changes than I thought at first sight. It’s still not clear for me if podofo_config.h is intended to be public or just used at build time, I did notice it was missing when building apps relying on podofo that complained PDF_INT*_TYPENAME were not naming types. Regarding deprecation of pdf_long as a ptrdiff_t, the reasons for it are quite clear but I don’t see exactly what’s the new status of pdf_long. for exemple, when I see it in use in PdfMemStream::GetCopy, I wonder how it will behave when the uint64_t will be interpreted as a size_t in the memcpy call.

[Podofo-users] A couple of segfaults
Hi,
The attached PDF (D1.pdf) gave me hard time this morning when I tried to open
it in PoDoFoBrowser. At first I’ve tracked down an overwrite of the filename
passed to PdfMemDocument constructor by Fontconfig (which I’ll try to handle
later). I rebuilt without Fontconfig and still crashed PoDoFoBrowser, this
time in PdfInputDevice::Clear.
To be honest, I did not even try to understand why m_pStream was null and if
it was legitimate or not, just checked for its nulliness and now it works.

[Podofo-users] Universal build on Mac OSX
Hi, I had some issues with the universal variant of the PoDoFo version (0.7.0) provided by MacPorts when building both Fontmatrix and Scribus. I must say I can’t make up my mind concerning the best way to fix it. I’ve filed a bug report on their tracker <http://trac.macports.org/ticket/19418> It led to the observation that there was a mechanism to detect endianess at configure time --as opposed to compile time-- which prevents to build a true universal version of the library.

Here is a random fix. It’s based on a step by step run of the example code I
did send. It’s really weird that it works as it introduces a logical error
when fixing a wrong array access. I won’t commit it ant will continue to
investigate. But if you need to quickly work around the issue, which was my
case, give it a try!

[Podofo-users] crash when creating pages
Hi,
I ran into an issue for which i cannot find an answer. It’s about creating
pages through a PdfMemDocument. In that matter, few lines of source code are
better than a long explanation. I join sample code which simply crashes, same
kind of construction in podofoimpose throws an exception in
PdfVariant::DelayedLoadImpl(). Might be obvious, or late, but I don’t see it.
In the hope it’s related to my local setup.

I don’t know about this specific project, but since XPdf has been turned into libpoppler, and considering there’s a _binding_ for Qt4, it’s trivial to write a simple PDF viewer. It’s something i should still consider to do for podofobrowser (the same i did for fontmatrix, a freetype rendering and a native Qt one, the factory thing in fact).

[Podofo-users] podofobrowser experiences
Hi, I’ve played a bit with Podofobrowser. And here is an insomnia-patch^^concept which allow viewing of content streams (to be honest, just paths). The result is not really interesting but i would be happy to get your opinions about the way it’s done and eventually if you see obvious problems which would prevent to add support for some kind of objects.

Although i’ve began by reimplementing the actual code in a separate class first, what led me to deeply clean up pdftranslator class.

I guess you’re right. I’ve came in thinking it would be good to make a new document after having been frustrated when deleting source pages was throwing exceptions.

[Podofo-users] podofoimpose tool
Hi, I’ve regenerated my password and can now commit again. It happened that I used podofoimpose these days and found some unexpected tricks I want to share with you. *Add a stamp to a document* Shame on me, don’t even have a real stamp at my "office". So I tried something and it worked! Say you have that official one page A4 doc on which you want to add a nice stamp named official.pdf. You have your stamp in the file stamp.pdf. You first have to create two files : == pdf.list == official.pdf stamp.pdf = ==stamponator.plan== 597.6 842.4 1 1 0 0 0 2 1 0 350 100 === Now you can run: podofoimpose pdf.list stamped-official.pdf stamponator.plan 0 *Make a tiled poster* I composed a 640x380 mm document in Scribus, I was thinking I could use the built-in Kprinter poster option to print it on my A4 laser printer. But no poster available on my OpenSuse box, so I thought I could give podofo a try. Here is the plan file, it’s still not exact but since i get my poster printed I don’t bother too much :) ==poster.plan== 597.6 842.4 1 1 0 16.56 172.4 1 2 0 -547.92 172.4 1 3 0 -1112.4 172.4 1 4 0 -1676.88 172.4 1 5 0 16.56 -497.6 1 6 0 -547.92 -497.6 1 7 0 -1112.4 -497.6 1 8 0 -1676.88 -497.6 === I ran a regular: podofoimpose large.pdf poster.pdf poster.plan 0 *Multiple business cards on a sheet* Classical need ==carte.plan 520.722 765.22 1 1 0 0 0 1 1 0 265.548 0 1 1 0 0 255.174 1 1 0 265.548 255.174 1 1 0 0 510.348 1 1 0 265.548 510.348 2 2 0 0 0 2 2 0 265.548 0 2 2 0 0 255.174 2 2 0 265.548 255.174 2 2 0 0 510.348 2 2 0 265.548 510.348 podofoimpose carte.pdf carte_imposed.pdf carte.plan 38.439 Note the sheet margin adjustment which lets room for the cut marks (if there is a relevant trim box[1] in the file), I can’t decide if it’s a bug or a feature! If the plan was generated automatically by a GUI app or something similar it would be a feature but when you have to compute it "by hand", it’s a real pain. Although it gives good results. If it does not work for you, don’t hesitate to ask questions (hm, and write patches!). [1] i don’t know if it’s documented somewhere but : "Trim" & "Crop" have the same length as for "Media" & "Bleed" so you can sometimes just use sed to do something useful without invalidate the XRef table.

But I found it was required to merge different keys from different Resources dictionaries into one to attach to the XObject. My idea was it is possible to have a font entry in a Resource dict. at a page level whereas a colorspace or an XObject has to be inherited from an ancestor. It’s just an example but I think it indicates that at some point you could have to pack resources from different objects into one dictionnary, though I didn’t checked with PDFs from various apps if it ever happens. -- Pierre Marchand - This SF.net email is sponsored by: Microsoft Defy all challenges.

For what I’m concerned, I was rather curious to see how Andreas would manage to retrieve all resources! To be honest, the way I do this in podofoimpose is a bit rough, asking for Resources dictionary at each level and go up with "rparent = rparent->GetIndirectKey( "Parent" );". You can read this in PdfObject* PdfTranslator::getInheritedResources(PdfPage* page). Another problem, at least I found it problematistic, was to have all resources in an unique object. I wrote PdfTranslator::mergeResKey(PdfObject *base,PdfName key, PdfObject *tomerge) to adress this. All in all, I would have like to find these methods into PoDoFo itself because not being a developer, I’m pretty sure these methods are suboptimal and not enough tested, if at all. -- Pierre Marchand - This SF.net email is sponsored by: Microsoft Defy all challenges.

[Podofo-users] GetResources
Can I expect PdfPage::GetResources() to return inherited resources ? Case yes, it does not here and something like page->GetResources()->GetDictionary() segfaults with a PDF generated by Scribus 1.3.3.10 which put resources in "/Pages". Although page->GetResources() does not but indeed returns 0. Case no, is there a "best" way to inspect inheritance tree ? -- Pierre Marchand - This SF.net email is sponsored by: Microsoft Defy all challenges.

Is there any static method or even global function in podofo's public API that
check if a file is a PDF one ?

It seems that's time to me to learn programming! I have to admit that I think first (only?) about features. I'll do my best to not forget that's now publicly available and have to be a bit more serious and maybe readable. -- Pierre Marchand - This SF.net email is sponsored by: Microsoft Defy all challenges.

I tried some things in it :
- take more than one file as input;
- compute some basic & well known imposition plans

[Podofo-users] About DeletePages()
hi, Would it be possible to really remove a page (or at least its content) from the page tree. Maybe with an extra arg like : void PoDoFo::PdfMemDocument::DeletePages ( int inFirstPage, int inNumPages, bool remContent = fase) Or just set a flag that tell PdfWriter to not output some page, or something else you like much. Here, I get page content into XObject in order to reuse it for imposition. I wan't to do that in place to keep all resources easily available for these XObjects. At the end, I would like to remove xobjectised pages to avoid having each content stream twice. -- Pierre Marchand - This SF.net email is sponsored by: Microsoft Defy all challenges.
