Identify chart shapes in a Word document

Aspose.Words Product Family

Is the Aspose Words API able to distinguish charts from other shapes in a Word document? Word interop provides a way to detect chart shapes via the InLineShape.HasChart property, but we are unable to find corresponding functionality in Aspose Words.
Please advise.

Is it possible to convert charts to images within the document?

Please advise.

Hi Lloyd,

Thanks for your inquiry. You can use the following code to convert Chart to Image:

Document doc = new Document(MyDir + @"in.docx");
DocumentBuilder builder = new DocumentBuilder(doc);
NodeCollection shapes = doc.GetChildNodes(NodeType.Shape, true);
foreach (Shape shape in shapes)
{
    if (shape.HasChart)
    {
        using (MemoryStream stream = new MemoryStream())
        {
            ShapeRenderer renderer = shape.GetShapeRenderer();
            renderer.Save(stream, new ImageSaveOptions(SaveFormat.Png));
            builder.MoveTo(shape);
            builder.InsertImage(stream);
        }
    }
}
int shapesCount = shapes.Count;
for (int i = 0; i < shapesCount; i++)
{
    Shape s = (Shape)shapes[i];
    if (s.HasChart)
    {
        s.Remove();
    }
}
doc.Save(MyDir + @"15.6.0.docx");

I hope, this helps.

Best regards,
