How to generate shape as image in FixedHTML

Hi team,

I’m working on converting a Word document to fixed HTML. However, when I convert documents that contain shapes, they are generated as SVG elements. I’d like to know how to generate these shapes as <img> elements instead. Are there any HtmlFixedSaveOptions available to help with this?

@AlpeshChaudhariDev I am afraid, there is no option to output shapes as img tag in HTML Fixed format.

Is there any other approach I can use to achieve this?

@AlpeshChaudhariDev You can try converting shapes in your document to images before converting document to HtmlFixed. Also, you can postprocess the generated HtmlFixed and replace SVG with the corresponding images.

Thanks @alexey.noskov for quick response.

Could you please provide a code snippet for how to accomplish this using Aspose.Words ? I would like to extract a shape from a Word document, convert it into an image, and then replace the original shape with the image in the document. How can I do this ?

@AlpeshChaudhariDev You can use ShapeRenderer to render shape to image. For example see the following code:

Document doc = new Document("C:\\Temp\\in.docx");

foreach (Shape s in doc.GetChildNodes(NodeType.Shape, true))
{
    // Process only top level shapes.
    if (s.GetAncestor(NodeType.Shape) != null)
        continue;

    // Render the chart to image and save the result into a stream.
    MemoryStream shapeImageStream = new MemoryStream();
    s.GetShapeRenderer().Save(shapeImageStream, new ImageSaveOptions(SaveFormat.Png));

    // Crete a shape with chart image and insert it after the chart shape.
    Shape imageShape = new Shape(doc, ShapeType.Image);
    imageShape.ImageData.ImageBytes = shapeImageStream.ToArray();
    imageShape.Width = s.Width;
    imageShape.Height = s.Height;
    // There might be other shape properties that you need to set, like wrapping or absolute position.
    // ...........

    s.ParentNode.InsertAfter(imageShape, s);
    // Remove chart shape.
    s.Remove();
}
doc.Save("C:\\Temp\\out.docx");

s.ParentNode.InsertAfter(imageShape, s);

this statement throwing the error : " Cannot insert a Shape into a GroupShape with a different markup language "

How can i resolve this issue.

@AlpeshChaudhariDev Please modify the code like this:

Document doc = new Document("C:\\Temp\\in.docx");

// Get all shapes and group shapes in the document.
List<ShapeBase> shapes = doc.GetChildNodes(NodeType.Any, true)
    .Where(n => n.NodeType == NodeType.Shape || n.NodeType == NodeType.GroupShape)
    .Cast<ShapeBase>().ToList();

foreach (ShapeBase s in shapes)
{
    // Process only top level shapes.
    if (s.GetAncestor(NodeType.Shape) != null || s.GetAncestor(NodeType.GroupShape) != null)
        continue;

    // Render the chart to image and save the result into a stream.
    MemoryStream shapeImageStream = new MemoryStream();
    s.GetShapeRenderer().Save(shapeImageStream, new ImageSaveOptions(SaveFormat.Png));

    // Crete a shape with chart image and insert it after the chart shape.
    Shape imageShape = new Shape(doc, ShapeType.Image);
    imageShape.ImageData.ImageBytes = shapeImageStream.ToArray();
    imageShape.Width = s.Width;
    imageShape.Height = s.Height;
    // There might be other shape properties that you need to set, like wrapping or absolute position.
    // ...........

    s.ParentNode.InsertAfter(imageShape, s);
    // Remove chart shape.
    s.Remove();
}
doc.Save("C:\\Temp\\out.docx");
