Major regression in Spire.pdf 3.6.135

Wed Feb 17, 2016 1:49 pm

Spire.pdf version 3.6.135 has a major issue in our system. 1 out of 15 documents fail to open correctly, Spire.pdf crashes.

Enclosed are 2 log files for a set of pdf files, on log file is of version 3.6.20, the other is 3.6.135.

Biggest problem:
in version 3.6.20:

Code: Select all: File C:\TestProd\c77e90a0-0f5b-4e5a-8cc7-6b42a7e1fe49.pdf processed OK File C:\TestProd\ff1ba28e-8532-4a3e-be4f-50c5fd8c891a.pdf processed OK

in version 3.6.135 (same files):

Code: Select all: File C:\TestProd\c77e90a0-0f5b-4e5a-8cc7-6b42a7e1fe49.pdf failed: System.ArgumentOutOfRangeException - Index and length must refer to a location within the string. Parameter name: length File C:\TestProd\ff1ba28e-8532-4a3e-be4f-50c5fd8c891a.pdf failed: System.ArgumentOutOfRangeException - Index and length must refer to a location within the string. Parameter name: length

This error happens very frequently in 3.6.135, one out of 15 files generate this error! Please fix a.s.a.p.!

Both versions have some other errors, see attached log files.

Due to privacy issues, the pdf files are sent to your e-mail address ([email protected])

Code used for testing is included as attachment.

Last weekend, I had the time to test the new version more in depth. Unfortunately, the error still occurs on some documents:

Code: Select all: System.ArgumentOutOfRangeException: Index and length must refer to a location within the string. Parameter name: length at System.String.InternalSubStringWithChecks(Int32 startIndex, Int32 length, Boolean fAlwaysCopy) at spr .ᜀ(spr᪠ A_0) at Spire.Pdf.PdfDocumentInformation.get_ModificationDate() at Spire.Pdf.Xmp.XmpMetadata.ᜀ(PdfDocumentInformation A_0) at Spire.Pdf.Xmp.XmpMetadata.ᜁ(PdfDocumentInformation A_0) at Spire.Pdf.PdfDocumentInformation.ᜁ() at sprᣴ.ᜍ()

I e-mailed a zip file with pdf files and errors to your support e-mail. Could you pick this issue up with priority?

Kind regards,

Sikke Kooistra

When will this hot fix be applied to the actual build for GA?
We already own the pro license but would like a solid build and not a test build.
Thanks

Dear Betsy,

I have done a very exstensive test on the lates version (3.6.260) . I testen 23000 pdf's from a big variety of sources and am happy to report that most files pass my test. However, I found 2 problems
a. Some pdf files give a Spire.Pdf.Exceptions.PdfDocumentException - Invalid contents array:

Code: Select all: Spire.Pdf.Exceptions.PdfDocumentException: Invalid contents array. at Spire.Pdf.PdfPageLayerCollection.?(PdfPageWidget A_0) at Spire.Pdf.PdfPageLayerCollection..ctor(PdfPageBase page) at Spire.Pdf.PdfPageBase.get_PageLayers() at Spire.Pdf.PdfPageBase.?() at Spire.Pdf.Widget.PdfPageCollection.?(PdfDocumentBase A_0, PdfPageBase A_1, List`1 A_2) at Spire.Pdf.PdfNewDocument.ClonePage(PdfDocumentBase ldDoc, PdfPageBase page, List`1 destinations) at Spire.Pdf.PdfDocumentBase.ImportPageRange(PdfDocumentBase ldDoc, Int32 startIndex, Int32 endIndex) at Spire.Pdf.PdfDocument.InsertPageRange(PdfDocument doc, Int32 startIndex, Int32 endIndex)

b. Some pdf files cause Spire.pdf to go into an infinite loop when saving a page to an image.

I sent a file with 2 expamples of error a (1.pdf and 2.pdf) and 1 example of error b to your support e-mail box. Testing was done with the same code as above. Can you provide a hotfix for these 2 issues?
