How do you set the size of an inline image added to Word docx document using RadDocument?
We need to add the image to a table and have the image scaled at 100%.  It scales the image at 156% when exporting to Word docx format
Images added outside of a table are sized at 100% and not scaled up.

When we use the following code to add an image outside of a table,.

//Setup RadDocument
RadDocument document = new RadDocument() { LayoutMode = DocumentLayoutMode.Paged };
document.SectionDefaultPageSize = PaperTypeConverter.ToSize(PaperTypes.Letter);
document.SectionDefaultPageOrientation = PageOrientation.Portrait;

const double pageMarginSizeInches = 0.5;
int marginSizeDip = (int) Unit.InchToDip(pageMarginSizeInches);
document.SectionDefaultPageMargin = new Padding(marginSizeDip);

//Add text and other document content

AddImageTable(document);

//add more text and document content//output to .docx file

//write to .docx file
using (Stream outStream = new FileStream("out.doc, FileMode.Create))
 {
  DocxFormatProvider provider = new DocxFormatProvider();
  provider.Export(document, outStream);
 }

//end of program

void AddImageTable(RadDocument document)
{
Section section = new Section();

System.Drawing.Bitmap testImage = ( a 500 pixel by 500 pixel bitmap image taken of an application window)

Table table = new Table();
table.StyleName = RadDocumentDefaultStyles.DefaultTableGridStyleName;
row = new TableRow();
TableCell cell = new TableCell() { PreferredWidth = new TableWidthUnit(TableWidthUnitType.Percent, 20.0f)  };

Paragraph par = new Paragraph();
par.Inlines.Add(new Span("Image test"))

cell.Blocks.Add(par);
row.Cells.Add(cell);

cell = new TableCell() { PreferredWidth = new TableWidthUnit(TableWidthUnitType.Percent, 80.0f) };
cell.Blocks.Add(AddImage(null, testImage, 0.0f));
row.Cells.Add(cell);

table.Rows.Add(row);

section.Blocks.Add(table);
document.Sections.Add(section);
}

static Paragraph AddImage(string imagePath, System.Drawing.Bitmap bitmapImage)
{   //add image from the assembly resource or from a Bitmap
 try
 {
  ImageInline imageTmp;
  Stream inStream;
  
  if (String.IsNullOrWhiteSpace(imagePath) == false)
  {
   inStream = Application.GetResourceStream(new Uri(imagePath, UriKind.RelativeOrAbsolute)).Stream;
   imageTmp = new ImageInline(inStream);
  }
  else
  {
   inStream = new MemoryStream();
   bitmapImage.Save(inStream, ImageFormat.Png);
   imageTmp = new ImageInline(inStream, new Size(bitmapImage.Width, bitmapImage.Height), "png");
  }  

Paragraph par = new Paragraph();
 par.Inlines.Add(imageTmp);  
inStream = null;
 return (par);
 }
 catch (Exception ex)
 {
  System.Diagnostics.Debug.WriteLine("AddInlinePicture() - exception - " + ex.ToString() + "\n\n");
  throw;
 }
}

Hello,

Please find attached a sample application that uses the code you sent us with some minor changes to make it run. As far as I tested this, both when showing the document in RadRichTextBox and exporting it the image is with its original dimensions. Please let me know if I am missing something in your scenario.

Looking forward to your reply.

Regards,

We ended up going with fixed width tables and table cells since the percentage scaling did not work out.
