这页类对象表示前景页面或背景页面的绘图区域。 Diagram 类公开的 Shapes 属性支持 Aspose.Diagram.Shape 对象的集合。此属性可用于从特定页面中提取所有图像。
以下代码从特定页面中提取所有图像。
//Call the diagram constructor to load diagram from a VSD file
Diagram diagram = new Diagram("ExtractImageFromShape.vsd");
//enter page index i.e. 0 for first one
foreach (Shape shape in diagram.Pages[0].Shapes)
{
//Filter shapes by type Foreign
if (shape.Type == Aspose.Diagram.TypeValue.Foreign)
{
using (System.IO.MemoryStream stream = new System.IO.MemoryStream(shape.ForeignData.Value))
{
//Load memory stream into bitmap object
System.Drawing.Bitmap bitmap = new System.Drawing.Bitmap(stream);
// save bmp here
bitmap.Save("ExtractedShape" + shape.ID + ".bmp");
}
}
}
