PDF Trailer is not recognized: trailer<< #80

Open vlasovsoft1979 opened 16 hours ago

Description If there is no space and no new line between "trailer" keyword and "<<" than the trailer is not recognized and we have "Malformed xref table section 'trailer<<......" error

Is there requirement that the "trailer" keyword should be separated with whitespace or new line?

How to reproduce We have the following PDF trailer:

trailer<</Size 46/Info 6 0 R/Root 20 0 R
/Encrypt 7 0 R
/ID[<5dd50a1b97f588ff90b175d49afe402f><5dd50a1b97f588ff90b175d49afe402f>]
>>

No new line after the "trailer" keyword. Foxit PDF reader opens this document successfully
