| Post subject: | Parser mis-handles dictionary values in content stream |
I have several PDF files where the page contents look like this: Code: /Part <</MCID 0 >>BDC q 0 -4000 3000 0 0 4000 cm /Im0 Do Q EMC But when I enumerate through the content objects using ContentReader.ReadContent(page), it tells me there are 7 objects in the sequence: "Dictionary" with 2 operands ("/Part" and "<</MCID 0 >>") "BDC" with 0 operands "q" with 0 operands "cm" with 6 operands "Do" with 1 operands "Q" with 0 operands "EMC" with 0 operands "Dictionary" is not a valid PDF operator, it appears the code cannot parse the dictionary value "<</MCID 0 >>" as a parameter for the BDC operator. |

Hi! We'd like to investigate this. Please send us one of the PDF files with that structure. Thanks. |

It won't let me, I found a 21 KB PDF that shows the problem but when I try to upload the attachment it tells me it's an invalid image |

I click on "Choose File" and select the file. When I click on "Add the file" a new window pops up saying "The upload is currently in progress" and a progress bar that scrolls from left to right. The underlying window changes to "Information", "The image file you tried to attach is invalid" and the progress bar scrolls forever |

You can upload ZIP files. You cannot upload PDF files. Please zip the PDF and upload it. http://forum.pdfsharp.net/viewtopic.php?f=2&t=832 |

Here's the zip It would be cool if the "Upload attachment" section of this page would remind folks "it must be a ZIP file" but I'm guessing this forum software is so old that it can't be modified anymore?
