Replacing an image in the document

[Kayani]

 

Hello,

I want to open a docx, find and replace an image in the header and replace another image in the body. How can I achieve that?

Thanks

Hi Waqar,

You can use the following approach for this:

DocxFormatProvider provider = new DocxFormatProvider();
RadFlowDocument document;

using (FileStream fs = new FileStream(@"..\..\test1.docx", FileMode.Open))
{
    document = provider.Import(fs);
}

var header = document.Sections.First().Headers.Default;
var headeImages = header.EnumerateChildrenOfType<ImageInline>();

var images = document.EnumerateChildrenOfType<ImageInline>();
foreach (var item in images)
{
    if (headeImages.Contains(item))
    {
        item.Image.ImageSource = new Telerik.Windows.Documents.Media.ImageSource(File.ReadAllBytes(@"../../green_tick.png"), "png");
    }
    else
    {
        item.Image.ImageSource = new Telerik.Windows.Documents.Media.ImageSource(File.ReadAllBytes(@"../../red_x.png"), "png");
    }
}

using (Stream output = new FileStream(@"..\..\output.docx", FileMode.OpenOrCreate))
{
   
    provider.Export(document, output);
} 

I hope this helps. Should you have any other questions do not hesitate to ask.
