#Wpf richtextbox flowdocument save how to

I know that I can wrap a FlowDocument up as text using the XamlReader, keeping the image elements but losing image data. I doubt this solution will win any awards, but it works. I quickly realized that I could just combine what I knew was working. I had to work on something else for a while, but this allowed me to come back with a fresh pair of eyes. MemoryStream stream = new MemoryStream(imageArr) īmpBitmapDecoder decoder = new BmpBitmapDecoder(stream, BitmapCreateOptions.None, BitmapCacheOption.Default) Private void LoadImagesIntoXML(string xml)īyte imageArr = Convert.FromBase64String(xml) MemoryStream stream = new MemoryStream() īmpBitmapEncoder encoder = new BmpBitmapEncoder() Į(BitmapFrame.Create((BitmapSource)src)) Private byte GetImageByteArray(BitmapImage src) XamlWriter.Save(flowDocument, writer ) //Throws error hereīi = (BitmapImage)replacementImage.Source String s = GetImagesXML(flowDocument) //temp I'll have to leave it alone for now though. This will take some further investigation. The only issue is that when I try and take the modified FlowDocument and use the XamlWriter.Save function, it errors on the newly created Image with 'Cannot serialize a non-public type '.BitmapFrameDecode'. For testing purposes I'm bypassing my database step and basically duplicating the image by creating binary, then taking the binary and turning it into a new image and adding it to the FlowDocument. This allows me to get binary from the bitmap image, store it to the database, and load it back up and display it right back into the FlowDocument. It uses BmpBitmapEncoder and BmpBitmapDecoder. I think I may have finally found a solution, which I will post below. Using (MemoryStream ms = new MemoryStream()) Private byte GetImageByteArray(BitmapImage bi) This function is where the problem is, i need a way to get the byte array Writer.WriteString(enc.GetString(bytes)) ReplacementImage = ()uic.Child īytes = GetImageByteArray((BitmapImage)replacementImage.Source) The inline has an object, likely an IMAGE!!! loop through replacing images in the flowdoc with the byte versionsįoreach (Inline i in ((Paragraph)b).Inlines)Įlse if (inlineType = typeof(InlineUIContainer))

Private string GetImagesXML(FlowDocument flowDocument) Using (StringWriter stringwriter = new StringWriter()) TextRange documentTextRange = new TextRange(, ) įlowDocument flowDocument = richTextBox.Document GetImageByteArray() is where the issue is.

#Wpf richtextbox flowdocument save how to

I tried using XamlWriter to get the text into XML, and then grab the images from the document separately and insert them as binary into the XML, but I can't seem to find a way to get the images to binary.ĭoes anyone have ideas on how to get the images into binary, separate from the text?

The images will be pasted in by the end user, not images included with the application. With DataFormats.Xaml, I've got the text of course, but no images. I've got it working so that I can save the flowdocument as DataFormats.XamlPackage, which saves the images, but the issue is that the text isn't searchable.

I've got a richtextbox, that I plan on saving to a database, which can be loaded back into the same richtextbox.
