Broken documents: read/get problems info (IPXS_Document's BrokenFlags) SOLVED

[zarkogajic]

Hi Support,

When opening a broken document (things like "xref chunks not found" or "misaligned object" etc) the "Broken Document" info will get displayed in the info bar.

How to read/retrieve/get the "bad document" string details? (which get displayed when clicking on "Show Problem Details...").

More info:
For one document, the pxvControl states "xhref chunks not found", and yes, IPXS_Document's Get_BrokenFlags has the SVF_XRefChunkNotFound set - so that's ok.

For another, I'm receiving 0 for nFlags ("SVF_Valid") while the pxvControl displays "misaligned object", so an issue with it? I've done a few more testst and it seems if the only issue is "misaligned object" (SVF_MissalignedObj) the BrokenFlags would always return "0" (SVF_Valid).

Also, why is "SVF_Corrected" flag set in most such broken documents (what does it actually mean)?

Hello žarko,

To get the BrokenFlags for the document, this property should be used. I've also updated the description for the https://sdkhelp.pdf-xchange.com/vi ... ationFlags enumeration.
As for the strings that are used

Code: Select all

	{
		{ SVF_XRefChunkNotFound,				loc_msg_docInfo_broken_xrefChunkNotFound },
		{ SVF_ErrorsInXRef,						loc_msg_docInfo_broken_errorsInXRef },
		{ SVF_InvalidObjRef,					loc_msg_docInfo_broken_invalidObjRef },
		{ SVF_BrokenObj,						loc_msg_docInfo_broken_obj },
		{ SVF_MissalignedObj,					loc_msg_docInfo_broken_misalignedObj },
		{ SVF_BrokenObjStream,					loc_msg_docInfo_broken_objStream },
		{ SVF_ErrorsInTrailer,					loc_msg_docInfo_broken_errorsInTrailer },
		{ SVF_UnrecoveredErrorsInTrailer,		loc_msg_docInfo_broken_unrecoveredErrorsInTrailer },
		{ SVF_LargerFileNotTruncated,			loc_msg_docInfo_broken_largeFileNotTruncated },
		{ SVF_WarnFutureObjRef,					loc_msg_docInfo_broken_warnFutureObjRef },
	};

Cheers,
Alex

Hi Alex,

Thanks.

Btw, can you double check internally? As : for a document(s) having only "misaligned object" the pxvControl will display the warning - while the BrokenFlags would return 0 (SVF_Valid).

I have a few such documents but cannot send here publicly.

Hello žarko,

Please send one of those files to the support@pdf-xchange.com with the link to this topic - we'll look into it.

Cheers,

Hi Alex,

Done.

Hello žarko,

I've modified the FullDemo project a little, so that the Pages Count field would show the Broken Flags:

Everything looks OK - the 64 == SVF_MissalignedObj flag.

Cheers,
Alex

Hi Alex,

Yes, I see this.

I'm receiving the same when testing with ipxv_document (resulting in SVF_MissalignedObj).

Please try opening as IPXC_Document via op.openDoc (IAFS_Name as input) -> BrokenFlags returns 0.

Hello žarko,

Not all of the errors are detected when the document is being just opened. To initialize all of the procedures, you should do:

Code: Select all

uint nCnt = doc.Pages.Count;

This will trigger reading of the pages' dictionaries and checking the structure for integrity.

Cheers,
Alex
