@DiDiDiDiDi You can use ShapeRenderer to render smart art and chart shapes to image. And OfficeMathRenderer to render office math equations. For example see the following code:

Document doc = new Document("C:\\Temp\\in.docx");
Iterable<Shape> shapes = doc.getChildNodes(NodeType.SHAPE, true);

int smartArtIndex = 0;
int chartIndex = 0;
for (Shape s : shapes)
{
    if (s.hasSmartArt())
    {
        s.getShapeRenderer().save(String.format("C:\\Temp\\smartart_%d.png", smartArtIndex), new ImageSaveOptions(SaveFormat.PNG));
        smartArtIndex++;
    }

    if (s.hasChart())
    {
        s.getShapeRenderer().save(String.format("C:\\Temp\\chart_%d.png", chartIndex), new ImageSaveOptions(SaveFormat.PNG));
        chartIndex++;
    }
}

Iterable<OfficeMath> maths = doc.getChildNodes(NodeType.OFFICE_MATH, true);
int officeMathIndex = 0;
for (OfficeMath m : maths)
{
    if (m.getParentNode().getNodeType() != NodeType.OFFICE_MATH)
    {
        m.getMathRenderer().save(String.format("C:\\Temp\\math_%d.png", officeMathIndex), new ImageSaveOptions(SaveFormat.PNG));
        officeMathIndex++;
    }
}
