//add picture data to this workbook. byte[] bytes = System.IO.File.ReadAllBytes(@"D:\MyProject\NPOIDemo\ShapeImage\image1.jpg"); int pictureIdx = hssfworkbook.AddPicture(bytes, HSSFWorkbook.PICTURE_TYPE_JPEG); //create sheet HSSFSheet sheet = hssfworkbook.CreateSheet("Sheet1"); // Create the drawing patriarch. This is the top level container for all shapes. HSSFPatriarch patriarch = sheet.CreateDrawingPatriarch(); //add a picture HSSFClientAnchor anchor = new HSSFClientAnchor(0, 0, 1023, 0, 0, 0, 1, 3); HSSFPicture pict = patriarch.CreatePicture(anchor, pictureIdx);
有時並不需要拉伸的效果
在結尾加上pict.Resize();即可使圖片自動伸縮到原始大小了
