Hi,

I get following exception if I try to load a big EMF file:

java.lang.NegativeArraySizeException
    at com.aspose.metafiles.cV.do(SourceFile:772)
    at com.aspose.metafiles.EmfMetafile.do(SourceFile:57)
    at com.aspose.metafiles.EmfMetafile.<init>(SourceFile:39)

IMHO, seems to be an overflow bug.

Here is an example file:

Thank you,
Stephan Michels.

Thanks for reporting, we will investigate and fix this problem.

Dear Stephan,

 

The attached file by you namely negative-size.emf is actually a WMF metafile and has been misnamed. WmfMetafile reads it correctly.

Thank you.

Is it possible to throw an exception if I try to load WMF files with EmfMetafile? Maybe it is possible to search and check for a signature. I see often also an OutOfMemoryException if I try to load something different than WMF/EMF with Metafiles(I must search to find reproducible test case).

ATM I can't really prevent incorrect files from being loaded with Metafiles. I can only check for exceptions and see if something goes wrong.

Do you mean Aspose.Metafiles should throw some exception say NotWMFFile if you try to load EMF file using WMFMetafile?

Yes, you can reuse the MetafilesException if you want. But a RuntimeException, especially a  NegativeArraySizeException shouldn't occur.

Thanks, Stephan.

Dear Stephan,

 

You can now download the latest version of Aspose.Metafiles 1.2.6.0 from this link.
