Hi, I am new to PDFSharp Reading the FAQ I understand that there is no PDFSharp viewer,and I wonder how hard is to implement such viewer? maybe it is something that I can contribute to?. I am a season .NET \WPF developer currently working on an application which need to display PDF including interactive forms I plan to use PDFSharp for extracting some information about the pdf document Thanks in advance Tomer |

As far as I understand it, a PDF page for PDFsharp is just a large string with post-script instructions.For a PDF viewer, you have to parse this string and execute the post-script instructions (i.e. draw things). The first step would be parsing the post-script instructions. Useful for extracting text, too. And then draw things. I think it's pretty hard to write a useful viewer. |

Thanks...but I thought that PDFSharp take care of this...I mean turn the pdf document into a collection of objects My assumption was that I "just" need to go over the collection of object(annotation,text,table) etc... And draw them...what am I missing? Thanks in advance Tomer |

As I wrote: a page is a big string and you have to parse it.And draw them...what am I missing? Search for "Extracting text" or look at this "sample": http://stackoverflow.com/q/38408763/1015447 When you draw it, you have to take the transformations into account. |
