| Post subject: | image.Elements.GetName("/Filter") -- Exception |
Hi! Sorry if this kind of issue is already solved. I couldn't find it in reasonable time... When I try to decode this pdf (in link provided) file I got exception: "Object reference not set to an instance of an object." I can't figure it out why this is happening. Any help would be appreciated. Thanks! Pdf: https://www.mediafire.com/file/xth0k0rz ... K.pdf/file Here are screenshots also:

Maybe "/Filter" is an array and not a single string. Maybe this post helps: viewtopic.php?p=5587#p5587 |

Thanks! It solved my problem! Before calling string filter = image.Elements.GetName("/Filter"), I iterate with foreach trough image.Elements.Values and if value.isArray() I used same function as /DCTDecode for extraction. |
