C＃richtextbox显示来自RTF的图像

Question

Why is it that my richtextbox only showed the RTF codes not the image? Here is the rtf codes:

{\\pict\\pngblip\\picw800\\pich600\\picwgoal6400\\pichgoal4800\\hex }

actually its to long, just deleted some.

but if the format starts with something like -> {rtf........, it showed the image

Thanks in advance

Answer 1

Assuming the WinForms RichTextBox, then yes, the contents of the RichTextBox has to be a valid RTF document, so it does need to start with an {\\rtf1 element and end with the closing bracket } .

Example:

{\\rtf1{\\pict\\pngblip\\picw800\\pich600......blah blah blah.....44AE426082}}

If your rtf glob is just a string variable, then you can do something like this:

richTextBox1.Rtf = @"{\rtf1" + picText + "}";

Answer 2

To display inline image in a rich textbox you have to do something like this:

//A RichTextBox with an image.
private void ImageRTB()
{
    //Create a new RichTextBox.
    RichTextBox MyRTB = new RichTextBox();

    // Create a Run of plain text and image.
    Run myRun = new Run();
    myRun.Text = "Displaying text with inline image";
    Image MyImage = new Image();
    MyImage.Source = new BitmapImage(new Uri("flower.jpg",    
    UriKind.RelativeOrAbsolute));
    MyImage.Height = 50;
    MyImage.Width = 50;
    InlineUIContainer MyUI = new InlineUIContainer();
    MyUI.Child = MyImage;

    // Create a paragraph and add the paragraph to the RichTextBox.
    Paragraph myParagraph = new Paragraph();
    MyRTB.Blocks.Add(myParagraph);

    // Add the Run and image to it.
    myParagraph.Inlines.Add(myRun);
    myParagraph.Inlines.Add(MyUI);

   //Add the RichTextBox to the StackPanel.
    MySP.Children.Add(MyRTB);
}
