Object stream and Cross reference stream

$

Hi,

 

I am creating a simple pdf which just displays letter 'A'. I created width array of Font object, as compressed object inside object stream.

I am also creating cross ref. stream which has 30 objects. One entry is of type 2 which is showing obj. id of objectstream with 0 as offset.

This pdf works fine , if i don't use object stream and cross ref. stream.

 

Here is how it looks:

 

Obj stream:

14 0 obj

<</Type/ObjStm/N 1/First 5/Filter/FlateDecode/Length 15 0 R>>stream

xœ34V0ˆ6463Sˆ

} ]

endstream

endobj

 

decoded stream is: 13 0[1366 ]

 

29 0 obj

<</Type /Catalog/Pages 28 0 R/PageMode /UseNone/PageLayout /SinglePage/OpenAction [27 0 R]>>endobj

 

Cross Ref. stream:

30 0 obj

<</Type/XRef/Size 31/W[1 4 1]/Info 21 0 R/Root 29 0 R/ID [<67e07d430c7a5c4cae26033cb3cc1e30> <67e07d430c7a5c4cae26033cb3cc1e30>]/Length 493>>stream

endstream

endobj

startxref

105159

%%EOF

 

When i open this .pdf, acrobat gives error saying root object is missing or invalid. Any help is appreciated.

 

Thanks
