Aspose.Words在指定位置插入图片、调整图片大小

在word模板中定义字符串，如“{图片1}”，用于定位图片插入的位置。原理：遍历所有段落，在指定位置插入图片，再将定位字符串替换为空

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22

NodeCollection paragraphs = doc.GetChildNodes(NodeType.Paragraph, true); foreach (Paragraph paragraph in paragraphs) {     int index = paragraph.GetText().IndexOf("{图片1}");     if (index >= 0)     {         string imgPath = "Tu1.png";         if (File.Exists(imgPath))         {             // 创建DocumentBuilder对象             DocumentBuilder builder = new DocumentBuilder((Document)paragraph.Document);             // 在段落中插入图片             builder.MoveTo(paragraph);             builder.Write(paragraph.GetText().Substring(0, index));             builder.InsertImage(imgPath);             builder.Write(paragraph.GetText().Substring(index + "{图片1}".Length));         }         paragraph.Range.Replace("{图片1}", "", false, false);     }     //插入其它图片     //... }

　　处理完所有图片后统一将所有图片宽度统一设为400px宽

foreach (Shape shape in doc.GetChildNodes(NodeType.Shape, true)) {     if (shape.HasImage)     {         // 计算图片原始宽高比例         double aspectRatio = (double)shape.ImageData.ImageSize.WidthPoints / shape.ImageData.ImageSize.HeightPoints;         // 计算高度         int height = (int)(400 / aspectRatio);         // 设置宽高         shape.Width = 400;         shape.Height = height;     } }
