xpsdocument

问题 I have a documentviewer which i used in my wpf project to show xps document reports of having around 600 pages which is working great. But from user point of view i like to show the current page number as a tooltip on my scrollviewer while dragging the scroll stating the current page number in view. Somewhat like in a PDF file like this - I was looking out for some ideas how to implement this. Just a current page number if not possible to show a thumbnail image would be good enough for me. Is

问题 UPDATE: We replaced the Image generation with an alternative that solves the issue (PDF to image) but I am going to leave this question open as I would like to understand if this is possible. On our website at http://www.cloudformatter.com, we were attempting to implement some code for processing our generated XPS files to image. Most all works well except for SVGs in the page which are included into the XPS document through VisualBrush resources. We took inspriation from the code here and

问题 I'm trying to implement a Paginator like this: public class MyPaginator : DocumentPaginator{ // ommitting details... public override DocumentPage GetPage(int pageNumber) { DocumentPage page = new DocumentPage(canvas); return page; } } It compiles, it runs, but the page is blank (white). the 'canvas' is an instance of System.Windows.Controls.Canvas. When I put it in a on-screen container like ScrollViewer it renders perfectly. XpsDocument _xpsDocument = CreateXpsDoc(myPaginatorInstance); The

问题 I am having some difficulties getting images contained in a FlowDocument to show when the FlowDocument is saved as an XPS document. Here is what I do: Create an image using the Image control of WPF. I set the image source bracketed by calls to BeginInit/EndInit. Add the image to the FlowDocument wrapping it in a BlockUIContainer. Save the FlowDocument object to an XPS file using a modified version of this code. If I then view the saved file in the XPS viewer, the image is not shown. The

问题 I keep running in to this code when researching, however copying this to my form gives me an error in the documentViewerElement part saying The name 'documentViewerElement' does not exist in the current context XpsDocument _xpsDocument=new XpsDocument("/path",System.IO.FileAccess.Read); IXpsFixedDocumentSequenceReader fixedDocSeqReader =_xpsDocument.FixedDocumentSequenceReader; IXpsFixedDocumentReader _document = fixedDocSeqReader.FixedDocuments[0]; IXpsFixedPageReader _page = _document

问题 When showing an XPS document in the DocumentViewer control of a WPF application it does not allow you to scroll its content on a touch enabled tablet just my moving your fingers over the screen. Instead it selects the text. The only way of scrolling on a touch enabled device is by using the vertical scrollbar. Is there a way to enable touch scrolling by moving your fingers on the content itself instead of on the vertical scrollbar? By overriding some styles I could prevent the text selection

问题 As I think, XPS files are like PDF files, but what is the structure od a XPS file? It's like PDF files? 回答1: XPS vs. PDF on CNET Excerpt: Behaving more like a ZIP archive file, XPS documents contain all the files necessary to re-create a document on any system. By changing the XPS extension to ZIP, you can view the files related to any XPS document. Specific files include embedded images and fonts so that, if someone doesn't have the same fonts installed on their machine, the XPS Viewer will

问题 I have many PowerPoint presentations that I need to be able to add to the res folder in my app. They will take up a lot of memory if I do not save them as XML, PDF, or XPS. PDF and android do not come together very easily at all so I choose the path of XML or XPS. I need these to be able to be viewed and/or then edited as a bitmap. I do not understand how a PowerPoint XML is able/implemented to be viewed or drawn onto the screen. I also do not understand how I would do the same with

问题 I was playing around with XPS in C# and used this example as a starting point: https://code.msdn.microsoft.com/windowsdesktop/How-to-Edit-XPS-file-in-WPF-724ef6fb I modified the example a bit and created a search and replace application for XPS documents. The output doesn't look very well: Copy and paste the question marks to an editor works well and gives me the correct characters. Now I've found out that when characters are not in the source XPS and new characters are in the target XPS,
